Report Summary
Biological surveys were undertaken as part of both the broad Australian Craysh Project (ACP)
and Australian Aquatic Biological Survey (AABS) and a targeted sub-project on the Gosford LGA
(Project #100056, Australian Aquatic Biological 2010). The main sponsors for this project were
Australian Aquatic Biological and Gosford City Council under their Ecological Research Grants
Program 2010 that was assisting with biological research projects for the whole Gosford LGA.
Surveys of the Gosford LGA are completed on a catchment/drainage basis and Brisbane Water
western shoreline from Point Clare to the Patonga and Mullet Creek region is the eighth catchment
area surveyed completely as part of the broader Gosford LGA project.
The area was surveyed between September 2011 and February 2012 when all the ephemeral creeks
and swamps had water in them. The ndings of that survey are presented in this report.
This area is a mixture of heavily urbanized catchments and pristine mountain streams. Generally,
streams start in the native forested coastal mountains, much of which is rugged and protected by
the Brisbane Water National Park. These streams ow down by a series of cascades and small
waterfalls, either directly into Brisbane Water or Broken Bay or ow down onto the at coastal
lowlands through the major urban areas. The majority of streams surveyed were surprisingly clean,
free of major exotic weed outbreaks with good numbers of native species. The catchment and
generally the creek systems were in excellent condition
Numerous freshwater craysh were found in the upper mountainous sections of the catchment.
None were found within the lowland catchments. No purely freshwater crabs were found within
the catchment, however, crabs were common in the brackish water sections. No freshwater mussels
were observed but freshwater snails were commonplace. Native sh species were abundant, mostly
gudgeons and Galaxiids.
Exotic species were present in small numbers. Specically, the plague minnow Gambusia holbrooki
was present in small numbers only. Of signicance was the discovery of the exotic White Cloud
Mountain minnow (Tanichthys albonubes) in numbers within Green Point Creek at Pearl Beach.
This was our rst record of this species in NSW waters.
Freshwater eels were recorded from numerous sites within the catchment and the largest eel
observed (over 5 kgs) dissuaded us from using traps in the catchment. All surveying was completed
by, hand, scoop net and visual observation.
Aquatic biodiversity and population densities across the catchment were very good and surveying
the area was a pleasure.
The full results of this aquatic biodiversity survey are presented in this report.

1 Background
The Gosford LGA is experiencing rapid growth and development. This high population coastal
area represents a signicant environmental asset that is fundamentally important to our lifestyle
and economy. Implementing the infrastructure needed to support the increased population,
agriculture and tourism must be undertaken so as to minimize or avoid ecological impacts on
coastal vegetation, wetlands and threatened species. It is essential that management agencies have
the information on hand to wisely plan the development and future of these fragile coastal regions.
Additionally, Gosford LGA will be increasingly affected by global warming and climate change.
Any decisions made today could have lasting effects on the biodiversity of this coastal area.
Currently, however, management agencies do not have access to all the appropriate information to
enable the protection of our coastal crustacean and sh species and their fragile aquatic habitats.
Over the last few years the Australian Craysh Project (ACP) and Australian Aquatic Biodiversity
Survey (AABS) has been surveying eastern Australia for freshwater craysh and aquatic fauna.
These surveys have made numerous important discoveries. In addition to recording new knowledge
and describing several new species of craysh in the region, the survey has also revealed that an
alarming proportion of the region’s endemic species appear to be facing serious threats.
With the support of Gosford City Council the whole of the Gosford LGA will be surveyed on a
catchment by catchment basis and the results collected will greatly increase the knowledge base
and allow better management of these fragile coastal ecosystems and help the conservation of our
aquatic species.
2 Introduction
This Central Coast Region is an area with a vast amount of variation from rocky sandstone
mountains to lowlying atland coastal communities.
Much of the upper catchment is protected by Reserves and Brisbane Water National Parks. These
upper catchments are generally sandstone mountainous/hilly areas with numerous creeks draining
the hills and owing down into the lower atter heavily populated suburban areas. The upper
catchments are mostly pristine with some suburban development encroaching up the hillsides. The
survey area includes heavily populated suburbs like Point Clair and Woy Woy to Ettalong Beach.
Freshwater biological surveys were conducted from Point Clare and followed the western shoreline
of Brisbane Water out into Broken Bay past Umina and Pearl Beach to Patonga. Then from Patonga
west along the Hawkesbury River including Mullet Creek. The results of our aquatic survey are
recorded in this report
Note: The Gosford LGA for the purpose of AABio biological surveying is divided into grids. This
survey represents grids: 86, 96, 106, 115 and 116.
3 Aim of this Study
The primary aim of Project 100056 is to determine what freshwater craysh occur where in the
Gosford LGA. Primarily freshwater craysh are the priority and the Gosford LGA represents a
signicant area for craysh distributions, yet little is known on the distributions of craysh in this
area. Prior to the start of this research project only two species have recorded distributions within
the LGA (Euastacus australasiensis and Euastacus spinifer) yet the extent of their distribution are

unknown. Additionally, the area includes a number of small coastal lagoons, lakes and streams all
with independent catchments draining directly to the Tasman Sea, that have been isolated from
each other for millions of years and many containing unrecorded craysh species.
The project also records information on all the other aquatic fauna found in the LGA as well as
information on landforms and vegetation. All this is in order to facilitate the better conservation
and management of the aquatic ecosystems of the Gosford LGA.
Note: For environmental and hygiene reasons (transfer of pests, diseases and weeds, etc.) each
of the catchments are treated as individual systems and are surveyed separately with equipment
and personnel being sterilized between catchments. A copy of our Hygiene Protocol and Code of
Practice is available online at www.aabio.com.au

4 Research Methods
A large number of sites within the catchment were surveyed (Maps 1-3) to identify potential habitat
areas and species present. The survey was relatively unobtrusive and consisted of various methods:
4.1 Methods
Site co-ordinates and altitude were recorded using a Magellan Explorist 600 handheld GPS.
Specimens were collected using a variety of methods to suit the conditions at each survey site.
Visual observation of craysh presence/activity. Generally burrowing activity is the most
common indication of craysh in the area, although visual observation is also often a useful
technique to record the presence of craysh that are active on the forest oor or stream bed
during sampling.
Visual search for shell fragments and remnants of craysh or molluscs. Craysh moult
their shells to grow a new larger shell discarding the old shell, they lose claws due to
ghting or claws are left from animal predation. Snail and mussel shells are often stranded
as water recedes or carried onshore by predators. Searching for shell remnants can give a
good indication of the species present, the numbers of animals in the population and an
indication of the predators in the area feeding on the craysh/molluscs as each predator has
its own signature re shell remains.
Active netting. Scoop nets were used to scoop the bottom sediments, under logs, through
leaf litter, under banks or through reedy sections, etc. This is a particularly important
method to detect species that do not respond to baits or traps and particularly effective in
muddy/turbid water. Three scoop nets were utilized: Small- 300 mm diameter hand held
scoop. Medium- rectangular rake with 600 mm x 200 mm opening. Large – 600 mm x 700
mm scoop net.
Structure removal and probing. Craysh and molluscs shelter under rocks and logs, etc.
and time was allocated to lifting such shelter objects and searching by hand for fauna. This
is another particularly important method to detect species that do not respond to traps or
nets.
Burrow excavation by hand. Most craysh species construct burrows, thus an integral part
of the survey involved careful excavation of burrows by hand to search for craysh. This is
a particularly important method to detect species that do not respond to traps or nets.
Most animals were examined at the collection site and released after identication. Some voucher
material was retained where appropriate, and all retained specimens were placed in transport
containers with a small amount of water and some vegetation from the site and returned to the
laboratory. Selected specimens were placed in glass aquaria and photographed. Crustacean
specimens were then euthanized by freezing for at least 24 hours and subsequently stored in clear,
labelled specimen jars containing 70% ethanol. Tissue samples were retained in cell lysis buffer
from selected specimens for subsequent DNA analysis, as part of the broader ACP.
These simple methods were used to nd and capture freshwater aquatic animals for identication
across the survey area. However, AABio employs a code of practice that is designed to limit the
transfer of any pests and diseases from one catchment to another. For each catchment, separate
traps and nets are utilized and boots, etc. of eld workers are sterilized between catchments.
All collections were authorized by the NSW Department of Industry and Investment under
Scientic Collection Permit P05/0077-4.1. All collections were authorized by the National Parks
and Wildlife Service, under Scientic Licence S13112.

5 Results and Discussion
Please note that results listed here are just a snapshot, they indicate the species at that site at that
time and may reect the species throughout the system. Over time during different conditions
different species or numbers may be present.
5.1 Crustaceans
5.1.1 Freshwater Craysh.
Prior to this research project only Euastacus australasiensis and Euastacus spinifer were recorded
from the Gosford LGA. Additionally, coastal habitats in NSW are known to contain two undescribed
species of freshwater craysh of genus Tenuibranchiurus and Gramastacus and these were also
targeted. Previously Euastacus australasiensis had been recorded from the Patonga region and this
survey conrms this record
Survey 100056-1 of Wamberal Lagoon identied two species of craysh in that catchment, an
endemic species Gramastacus sp. and an invasive introduced species Cherax destructor. Both
these species were specically searched for in the area but we were unable to nd any indication
of their presence.
Both Wyong LGA to the north and Gosford LGA to the south represent a signicant freshwater
craysh distribution area. Though the knowledge base is small there seems to be a cut off line
roughly running from Wamberal Lagoon, through Narara and then up through Central Mangrove
that represents a species distribution line with one species, Euastacus spinifer occurring on both
sides, two species Cherax setosus and Gramastacus sp. only north of the line and one species
Euastacus australasiensis only south of the line. This project will map that line and the distribution
of these craysh species along the line, and the surrounding region. A scientic manuscript on
those ndings is proposed.

5.1.2 Euastacus Craysh
We were able to conrm the presence of Euastacus australasiensis within the upper catchments of
the survey area. They were plentiful in many of the areas surveyed and were obviously thriving.

Figure 4. Euastacus australasiensis WPT016 Patonga
Euastacus spinifer was expected to be within the survey area, yet despite our efforts we were only
able to conrm its presence from one location. Much of the upper catchment where it was expected
to occur was difcult to access so we expect with further surveying it would be found in numerous
other streams. WPT024 Kariong Brook Falls, Kariong.
5.1.3 Gramastacus Craysh
No craysh have been collected within any of the catchment areas surveyed. Suitable habitat areas
were not recorded from the survey area.
5.1.4 Cherax Craysh
Yabbies Cherax destructor were not found within the catchment. This was a good sign and it is
hoped that better education will keep them out.

5.1.5 Freshwater Shrimp - Atyidae
Freshwater shrimp surprisingly were not recorded from the catchment. I expect this was just bad
luck rather than the area being unsuitable.
5.1.6 Freshwater Crabs
Freshwater crabs were targeted in this greater survey of the Gosford LGA. This is the eighth
survey of the region and to date we have not found freshwater crabs in any of the freshwater
environments. We have found Haswell’s Shore Crab Helograpsus haswellianus; these are marine
crabs that penetrate into freshwater environments.
Features: Pale honey-brown, varies to dark brown; body rounded; edge of carapace behind eyes
has single, small notch; legs smooth and slender without long bristles; to 30 mm across.
Notes: Burrows among grass, under rocks or debris, at or above high water, on river bank or well
back on mud-at in moist clay to coarse, dirty sand. Sheltered bays and estuaries; penetrates well
up river. Indigenous, from SA along east coast north to Mackay, Qld. Additionally, in the brackish
water sections of the feeder streams and Narara Creek, marine Mud Crabs (Scylla serrate) were
common.
5.2 Fish Species
5.2.1 Poeciliidae
Gambusia holbrooki are an introduced species that is a major pest and is having devastating
repercussions on our native species. They are live bearers protecting their eggs and young, they can
survive in both fresh and marine environments being an exceptionally robust species, surviving in
conditions that will kill most native species. They eat the same food as our native species and can
eat the eggs and larvae of our native species.
Figure 5. The mosquito fish or plague minnow Gambusia holbrooki
Mosquito sh Gambusia holbrooki were exceptionally rare in the catchment. Most of the creek
systems were in pristine condition with intact riparian zones. Mosquito sh prefer slow moving
water with open sky, they don’t like owing water with a heavy canopy. Most of the upper
catchments with good canopies had no mosquito sh just native species. In the few open drain

human altered habitats, mosquito sh were more common.
Other pest and exotic sh species like swordtails, guppies, mollies, carp and goldsh were all
absent from the catchment. Much of eastern NSW is impacted by these pest species and their
absence in the survey area was fantastic news and very encouraging for the future health of the
local environment and prosperity of the native aquatic fauna.

5.2.2 Characidae
The White Cloud Mountain minnow (Tanichthys albonubes) is an introduced freshwater sh
species usually restricted to home sh tanks. It is a robust species and a member of the carp family
being a native of China.
Their robust nature and bright colouration makes them popular as an aquarium species and they
are not normally found in natural waterways of NSW. Three specimens were found over a 6 metre
section of stream and indications are they are doing well in the stream. There is only two known
feral population of this exotic species in NSW, one here and one at Piles Creek near Somersby.

5.2.5 Galaxiidae
Common jollytails Galaxias maculatus were quite common within the catchment survey area.
Their presence was exceptionally good news and does reect the generally good water quality
conditions of this area. They are a common species that likes clear, clean owing water at lower
elevations. WPT005 Bluesh Crescent. WPT014 Green Point Creek crossing Diamond Road,

5.3 Anguillidae
Freshwater eels Anguilla reinhardtii were expected to be in most of the permanent creek systems
however they were not targeted in this survey. The largest eel sighted in this series of surveys
approximately 5 kgs in weight was seen at The Broadwaters, Tascott. WPT004 The Broadwaters,
Tascott. Smaller eels were seen at WPT014 Green Point Creek crossing Diamond Road, Pearl
Beach.
5.4 Mollusca
5.4.1 Sphaeriidae
Pea shell freshwater mussels (Pisidium sp.) were specically searched for after their discovery in
Erina Creek. However, despite our best efforts we were unable to identify any within the survey
area.
5.4.2 Planorbidae
Freshwater nnails Glyptophysa gibbosa were found in good numbers where suitable habitat was
available so this was an excellent sign. WPT002 Coorumbine Creek crossing Manooka Road,
Point Clare. WPT008 Railway Street, Woy Woy.
5.4.3 Lymnaeidae
The American ribbed uke snail Pseudosuccinea columella is native to North America and has
been introduced to Australia. It is common in NSW coastal drainages. WPT002 Coorumbine Creek

5.7 Site Results
Generally the survey area was in an excellent state without any large aquatic weed outbreaks, only
small numbers of exotic species and excellent native aquatic biodiversity.
5.7.1 Point Clare
A tributary of Coorumbine Creek WPT001was surveyed at the corner of Singleton Road and
Finch Place.
Figure 12. The end of the concrete drain discharged into a larger pool
Here the creek is a concrete drain
with rock retaining walls. Water
was owing down the drain and
discharging into the earthen creek
bed at the end of the drain. The
rst big pool was sampled and
plague minnows were the main
species in residence.

Coorumbine Creek crossing Manooka Road WPT002 was surveyed. The area here is a wetland
reserve consisting of small owing streams and shallow ephemeral swamps. Mostly a paperbark
swamp with scattered eucalypts and a ground cover of saw grass, ferns, vines, etc. This reserve
area was a haven for frogs and all the shallow ponds and pools were teeming with tadpoles. Two
or three different tadpole species were present as well as two species of freshwater snails and
numerous macroinvertebrates from mud-eyes to red wrigglers.

5.7.2 Tascott
Small stream owing directly into Brisbane
Water at the crossing on Glenrock Parade
WPT003 was surveyed. Here the creek was
clear owing down the side of the forested
mountain via a series of larger waterfalls and
smaller cascades. No craysh were captured
but the stream looked highly suitable for
Euastacus craysh.

Figure 16. WPT004 The Broadwaters
The northern branch of the creek was surveyed at WPT004 The Broadwaters. Here the creek was
more a sculptured drain through suburbia with grassy banks. The stream starts in Brisbane Water
National Park and ows down the mountain via a waterfall to the lower atter residential area. The
stream at the survey site was owing with clear water and plague minnows and macroinvertebrates
were common in the stream. Additionally, a very large 5 kg long nned eel was in residence in the
concrete pipe under The Broadwaters.

Figure 18. WPT005 Common jollytails
The southern branch of the stream was surveyed at WPT005 Bluesh Crescent. This branch also
ows down the mountain with a waterfall in the upper reaches. This branch had a stronger ow
than the northern branch and was deeper. Schools of common jollytails Galaxias maculatus could
be seen hunting and frolicking under overhanging branches. A few plague minnows were also
present. No other species were identied other than macroinvertebrates.

Further down WPT019 opposite Dolphin Street the creek was wider with cumbungi and some
parrot’s feather. Exotic parrot’s feather or Brazilian water milfoil Myriophyllum aquaticum is a
native of South America. It grows fast in sunny, nutrient rich waters and forms dense stands that
impede water ow. No native sh were visually present only mosquito sh Gambusia holbrooki.
I had a chat to some of the locals in the area and they reported that the Galaxiids were also in the
stream above the waterfalls and that there is also usually long neck turtles in the creek. Large
numbers of mullet were also present in the brackish water.

Figure 22. WPT006 Seabrook Reserve
The creek through Seabrook Reserve WPT006 beside
Melaleuca Crescent was surveyed. Here the creek
was well shaded with tree ferns and scattered trees.
The creek was clear owing with some exotic purple
cunjevois Colocasia esculenta.
5.7.3 Woy Woy
A small drain type creek was surveyed at WPT008
between Railway Street and the railway line. Here
the creek was clear owing with some iron bacteria.
Figure 23. WPT006 the creek is
well shaded with tree ferns
The creek bed was mostly cumbungi covered that had been attened with strong ows, banks
were grassy one side and scrubby with scattered paperbarks the other. The substrate was heavy
litter with some aquatic weeds
and some light iron bacteria.
Plague minnows and macro
invertebrates were present as
well as very large numbers
of two species of freshwater
snails.
Figure 24. WPT008 the creek was
full of freshwater snails
A native species of freshwater
snail Glyptophysa gibbosa
was in good numbers which
was an excellent sign. Another

was also present in large numbers. This snail species is known to transmit liver uke. In NSW,
about 20 million sheep and 2 million cattle graze pastures where liver uke Fasciola hepatica
commonly occurs. During its life cycle, liver uke must develop in a particular type of small
freshwater snail (NSW DPI Primefact).
Figure 25. WPT009 Veron Road
The creek crossing Vernon Road at WPT009 was surveyed. The creek here was owing without
any problematic weed outbreaks. Only Gambusia was present with eastern water dragon lizard
along the banks and dusky morhens wandering the stream edges.

5.7.4 Umina Beach
The creek crossing Australia Street at WPT010 was surveyed. Here the creek was an excavated
channel with grassy banks and banksia trees along the shoreline, it was owing with deep water.
Figure 28. Australia Street at WPT010. Note the pied cormorant feeding in the creek
Some ribbon weed was present and striped gudgeon Gobiomorphus australis were present in good
numbers as well as macroinvertebrates. A pied cormorant thought it was good shing and caught
a feed of gudgeons from the creek whilst I watched.

Kahibah Creek crossing Brisbane Avenue at WPT011 was surveyed. Here the creek had grassy
banks with scattered paperbarks and eucalypts. Pacic black ducks Anas supercilious were in
residence as were striped gudgeons and plague minnows. Some exotic parrot’s feather was also
present.
Figure 29. Kahibah Creek crossing Brisbane Avenue at WPT011
The creek at the end of Greenhaven Drive WPT012 was surveyed, it looked good with a small
owing creek off the forested mountain with some cabbage palms. We expect Euastacus craysh
to be further upstream.
Point Clare to Patonga and Mullet Creek Aquatic Survey Report 29

Australian Aquatic Biological P/L Report 100056-8
Iluka Creek at Homan Close WPT013 was surveyed. Here the creek was a concrete drain devoid
of aquatic life, however, there was a side stream entering the drain. The side stream had shallow
sandy substrates with deeper pools and was clear owing through a forested area with scattered
cabbage palms. The creek looked excellent with macroinvertebrates and we expect Euastacus
further upstream.
5.7.5 Pearl Beach
Green Point Creek was surveyed at several sites. At the crossing on Diamond Road WPT014. The
creek here was strongly owing over a sandy stream bed. There were shallow areas and deeper
holes. The banks had some rock retaining walls but were well shaded with ferns and palms, etc.
The creek was extremely healthy with abundant aquatic species present. Some plague minnows
were present, we observed a small long nned eel, several at headed gudgeon, many striped
gudgeons and common jollytails.

Figure 31. Green Point Creek
Further upstream at Tourmaline Avenue WPT015 the stream was again sandy based with deeper
holes and looked in excellent condition. We surveyed the stream nding only dozens of striped
gudgeons and surprisingly the White Cloud Mountain minnow Tanichthys albonubes. The White
Cloud Mountain minnow is an exotic freshwater sh from China. It is a species that would normally
be found in a sh tank so it is alarming that this exotic species is established in numbers within
the stream. I did some research on this species and found that, NSW DPI has known about this
feral population since late 2002 and continues to monitor the situation. Unfortunately, one of the
specimens collected was gravid so conditions were suitable for breeding which is a big worry.
Discussions with residents in the area report Australian Bass and eels in the deeper holes and
freshwater craysh further upstream.

5.7.6 Patonga
An unnamed watercourse crossing Patonga Drive at WPT016 was surveyed. This was a tiny stream
owing down the mountain through the coastal heath. The water was clear with scattered deeper
pools and Euastacus australasiensis was easily seen wandering the creek beds in large numbers.
Figure 33. Creek crossing Patonga Drive
Large numbers of juvenile
craysh were scattered
throughout the clear pools
with the odd larger craysh
amongst them.

5.7.7 Kariong
Small pond beside Tommos Loop Trail WPT021, Brisbane Water National Park. An unnamed
tributary of Mullet Creek was survey. This crystal clear pond had clay banks and large numbers of
Euastacus australasiensis in residence plus large couta dragon y larvae.
WPT027 and WPT023 a small stream owing through the heath country. Euastacus australasiensis
was in all the small pools in the stream.
Kariong Brook Falls (gure 2) was surveyed at WPT024 just below the waterfall. Here the brook
was deep, clear and owing strongly. Euastacus spinifer was in residence.
A small clear owing stream crossing Thommos Track was surveyed at WPT031. Here Euastacus
australasiensis was in residence.

6 Conclusion
Both Euastacus spinifer and Euastacus australasiensis were confirmed from the survey area which
was a key component of the greater research project. No other species of freshwater crayfish were
identified from the area which greatly increases our knowledge of the area.
The upper catchments were protected by the Brisbane Waters National Park which is the area in
which the crayfish resided, this was fantastic and provides a lasting security for their ongoing
health and prosperity. Aquatic biodiversity surveys of the streams in the lower urbanised areas was
excellent with native species predominating and only exotic Gambusia holbrooki in small numbers
and mostly restricted to the larger altered open sky areas.
Generally, the streams were in excellent condition with few exotic weed outbreaks or noticeably
polluted water. Large numbers of exotic or invasive species were absent and the only finding
of significance from the area was the discovery of White Cloud Mountain minnow Tanichthys
albonubes in Green Point Creek. This infestation must be considered a major concern. Seemingly,
this exotic species has now spread to Piles Creek, Somersby and we expect to other NSW public
waters.
7 Recommendations
This survey records the current disposition of species and the status of the ecological health of
streams in the Point Clare to Mullet Creek area. Currently the area is generally in excellent health
and this survey provides a baseline for any future comparisons. The following recommendations
are offered to Gosford City Council for the survey area.
• Serious consideration needs to be given to projects requiring the landscaping and replacing
of natural waterways with manmade structures. Greater effort needs to be given to retaining
or replanting riparian zones to limit sunlight onto natural waterbodies.
• Continued support and encouragement of local environmental community or landcare
groups to continue with riparian regeneration and weed control, etc.
• Biodiversity monitoring of the freshwater catchment streams on an ongoing basis would
also be recommended. To obtain significant information approximately 10 sites should be
monitored for aquatic biodiversity twice per year (winter/summer) on the same day and
then over time, trends can be seen, etc.
• Water quality monitoring of the freshwater catchment streams on an ongoing basis would
also be recommended. To obtain significant information approximately 10 sites should be
monitored for water quality twice per year (winter/summer) on the same day and then over
time, trends can be seen, etc.
• Continue to educate the residents and commercial entities on pollution reduction at source.
• Continue to educate the residents and commercial entities on the dangers of exotic flora
and fauna and the consequences of escape into the environment.
• Continue to educate the residents and commercial entities on aquatic weeds and how to
identify outbreaks, with monitoring of their local streams to identify outbreaks early.
• Control or elimination strategies should be developed to remove the White Cloud Mountain
minnow Tanichthys albonubes in Green Point Creek. This should be considered a priority
as this creek can act as an infection source for all other coastal creeks in NSW.
