Observations were made across a wide range of species and aresummarised in Table 2. Samples provided to Biosecurity Queensland for further testing havebeen summarised in Tables 3 and 4. Biosecurity numbers include some samples provided bysourcesother than Fisheries Queensland during Phase 1 (Table 3).21
