Australia's Maritime Jurisdiction Map with 2018 Treaty Update

A wall map from Geoscience Australia updated in March 2020 depicts Australia's maritime jurisdiction, including its extended continental shelf approved in April 2008. The map uses a blue Etopo2 seabed background and NASA Blue Marble land imagery and reflects the 2018 Australia-Timor-Leste Maritime Boundaries Treaty. The map is indicative and should not be used as a definitive source, as some limits may be subject to change.

Use Cases

• Visualizing maritime zone boundaries based on the described continental shelf and territorial sea baselines.
• Referencing historical treaty changes based on the inclusion of the 2018 Australia-Timor-Leste Maritime Boundaries Treaty.
• Creating educational or reference materials based on the combined seabed and land imagery from Etopo2 and NASA.

Strengths

• Updated in March 2020 to incorporate a major 2018 international treaty.
• Combines authoritative data sources: seabed imagery from Etopo2 and land imagery from NASA Blue Marble.
• Explicitly notes the April 2008 approval date for the extended continental shelf by the Commission on the Limits of the Continental Shelf.

Limitations

• The description metadata is limited; actual data quality and detail require manual inspection after download.
• The map is described as indicative only and not a definitive source, with limits subject to change.
• Column-level documentation is absent; field semantics must be inferred after download.
