  • Marine Monitoring Program: 2024-25 Summary Results Booklet
    (Great Barrier Reef Marine Park Authority, 2026) Great Barrier Reef Marine Park Authority
    The Marine Monitoring Program 2024-25 Summary Results Booklet contains information on the condition of inshore water quality including pesticides and health of corals and seagrass at regional level. It also provides an overview of key environmental pressures to the inshore region and case studies on major flood event sampling that occurred in the 2024-25 monitoring year.

    October 2024 to 30 September 2025) with reference to 20 years of monitoring data. The program design includes the collection of samples along transects in the Cape York, Wet Tropics, Burdekin, Mackay-Whitsundays and Fitzroy regions year-round, with higher frequency sampling during the wet season to better characterise this period of episodic river discharge. Satellite imagery and remote sensing are linked with in situ monitoring data to estimate the exposure of inshore areas to end-of-catchment loads from rivers for all Reef catchment regions.
  • Marine Monitoring Program: Annual Report for Inshore Seagrass Monitoring 2024–25
    (Great Barrier Reef Marine Park Authority, 2026) McKenzie, L.J; Collier, C.J; Langlois, L.A; Brien, H; Wilson, N; Yoshida, R.L; Great Barrier Reef Marine Park Authority
    This document reports on the long-term health of inshore seagrass meadows in the Great Barrier Reef. Results are presented in the context of the pressures faced by the ecosystem. Long-term health of inshore seagrass meadows is measured through seagrass abundance and resilience, which are summarised as the Seagrass Index, and supported by information on the proportion of colonising species, reproductive status, meadow extent, epiphytes on seagrass leaves and macroalgal presence.
  • Marine Monitoring Program: Annual Report for Inshore Coral Reef Monitoring 2024–25
    (2026) Thompson, A; Davidson, J; Logan, M; Thompson, C; Great Barrier Reef Marine Park Authority
    This report details the condition of 30 inshore coral reefs monitored under the Great Barrier Reef Marine Monitoring Program and 6 inshore coral reefs monitored by the Australian Institute of Marine Science’s Long-Term Monitoring Program. Results are presented in the context of the pressures faced by the ecosystem and their ramifications for the long-term health of inshore coral reefs.
