2025 Marine Results Summary
The 2024 Report Card has revealed a range of waterway health scores from ‘A’ to ‘C’ across the region’s 18 key graded areas, reflecting results for five freshwater basins, eight estuary areas and five marine zones.
For only the second time in 10 years, there is no overarching ‘D’ grade to be seen in the region, with the ‘D’ grade in the Whitsunday Inshore marine zone lifting to a ‘C’ in 2024. Key updates in the 2024 Report Card include the inclusion of pesticide data in the Whitsunday Inshore marine zone for the first time. Fish barrier results, which are updated on a four-yearly cycle, have been updated in the 2024 Report Card for both freshwater and estuary sites.
- Freshwater: Overall freshwater basin grades remained the same as the previous reporting period (no change from the 2022 Report Card).
- Estuary: Vines Creek and Carmila Creek estuaries both received grade improvements. Vines Creek improved from ‘C’ to ‘B’ and Camila Creek improved from ‘B’ to ‘A’.
- Marine: Whitsunday Inshore marine zone grade improved from ‘D’ to ‘C’ influenced by decreased concentrations of nutrients, chlorophyll-a and the incorporation of pesticide data.
