Australia's Benthic Marine Bioregions for Seafloor Habitat Management

A technical report from Geoscience Australia, last updated in May 2026, describes the benthic bioregionalisation for Australia's Exclusive Economic Zone. It covers the sea floor in the 80% of the zone that lies beyond the continental shelf break. The report details the datasets used, describes each bioregion, and provides an evaluation of the methodology.

Use Cases

• Marine spatial planning based on described patterns of biological distributions and physical habitats.
• Subdividing marine bioregions for management based on the included physical data examples.
• Evaluating seafloor conservation strategies based on the bioregion descriptions and methodology evaluation.

Strengths

• Covers 80% of Australia's Exclusive Economic Zone beyond the continental shelf break.
• Includes a detailed evaluation of the methodology's strengths, weaknesses, and future work.
• Provides examples of how physical data can be used for management subdivision.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented as an HTML report; the underlying raw datasets are not directly accessible.
