Parks Australia Natural Values Ecosystems 2026: Marine Habitat Map for Australian EEZ

Parks Australia's 2026 draft map delineates marine ecosystems by habitat and depth across the Australian Exclusive Economic Zone. The dataset uses a 250m resolution grid from Geoscience Australia's AusBathyTopo 2024 and incorporates Seamap Australia's National Benthic Habitat Layer for seagrass and coral reef data. This broad-scale categorisation provides a functional, geo-physical perspective on marine ecosystems but is not a validated habitat map.

Use Cases

• Modeling marine ecosystem distribution based on habitat and depth classifications.
• Assessing national-scale conservation priorities based on mapped ecosystem complexes.
• Integrating seagrass and coral reef occurrence data from the Seamap Australia layer for regional studies.

Strengths

• National coverage of the Australian Exclusive Economic Zone.
• Based on a 250m resolution bathymetric/topographic grid (AusBathyTopo 2024).
• Incorporates revised input datasets and updated classification rules since the previous release.

Limitations

• Dataset is in draft format and may be updated at any time.
• Description metadata is limited; actual data quality requires manual inspection after download.
• Uses interpolation to fill data gaps, which may introduce uncertainty.
