We recognise Aboriginal and Torres Strait Islanders as the sovereign Traditional Owners of Australia and thank them for their stewardship of this Country, its lands, waters and skies. We respectfully acknowledge their culture and customary practices, and pay respect to their Ancestors, Elders and future leaders.
For the first time, the State of the Environment report includes a strong Indigenous narrative across all 12 thematic chapters, a narrative crafted through recognising the leadership, collaboration and authorship of Indigenous Australians who continue their connection as Traditional Owners to their lands, waters and skies.

On 28 March 2025 the government assumed a Caretaker role. Information on websites maintained by the Department of Climate Change, Energy, the Environment and Water will be published in accordance with the Guidance on Caretaker Conventions until after the conclusion of the caretaker period.
Due to technical issues, graphs, maps and tables are currently not displaying within the main content, however, are available via the chapter resources navigation bar. We are working on a solution to resolve the issue.
Graphs, maps and tables
m = metre
C = carbon; mg/m3 = milligram per cubic metre
Note: Black dots represent data points, and the lines (and shading) represent the linear regression (and confidence intervals) of the data after the seasonal cycle has been removed. Colours show the direction and statistical significance of the trend (blue = decreasing; red = increasing; black = no statistically significant trend).
Source: Data from the Integrated Marine Observing System
DHW = degree heating weeks; m =metre; SE =standard error
Notes:
- For Cocos (Keeling) Islands and Ningaloo Reef, open and closed circles represent 2 separate monitoring programs.
- SE bars give an indication of the variability of the underlying measurements.
- See Figure 5 for a national summary.

GBR = Great Barrier Reef
Note: Percentages of coral and kelp represent the sum of all live hard corals and canopy-forming seaweeds (including laminarian kelps and fucoid seaweeds), respectively. Differences between the 2011–15 average and the 2016–20 average (periods represented by the 2 grey-shaded blocks in the panels) are expressed as change per year on the map. (See Stuart-Smith et al. (2021a) for additional detail and description of methods.)

GBR = Great Barrier Reef; RFTI = Reef Fish Thermal Index
Note: Increases in this index reflect changing community composition with increasing local abundance of reef fish that prefer warmer temperatures, whereas decreases reflect increasing species that prefer cooler temperatures. The values can be interpreted as the typical temperature preference for fish surveyed (measured in °C). Differences between the 2011–15 average and the 2016–20 average (the periods represented by the 2 grey-shaded blocks in the individual trend plots) are expressed as change per year on the map. (See Stuart-Smith et al. (2021c) for additional detail and description of methods.)

cm = centimetre; GBR = Great Barrier Reef; kg/m2 = kilogram per square metre
Note: Values are log-transformed kilograms per 50 m × 10 m patch of reef. Separate trends are shown for sites monitored inside marine protected areas with no-take regulations (red lines) versus areas with some or all fishing allowed (orange lines). Differences between the 2011–15 average and the 2016–20 average (the periods represented by the 2 grey-shaded blocks in the individual trend plots) are expressed as change per year on the map. (See Stuart-Smith et al. (2021c) for additional detail and description of methods.)
LPI = Living Planet Index
Note: Coloured lines show the average trend; shading around the trend lines show 95% confidence intervals. Methods for calculating trends are provided in McRae et al. (2017); see Stuart-Smith et al. (2021c) for additional detail.
CAPAD = Collaborative Australian Protected Areas Database; m = metre
