Australia-Timor-Leste Maritime Boundary Treaty 2019

Geoscience Australia's 2019 database update incorporates the ratified maritime boundary treaty with Timor-Leste. The digital representation covers a geographical extent from 9.5°S to 11.5°S latitude and 126°E to 128.5°E longitude. This product is part of the Australian Maritime Boundaries database, published in consultation with Commonwealth agencies.

Use Cases

• Analyze the treaty-defined maritime boundary geometry within the specified latitude and longitude limits for jurisdictional mapping.
• Integrate the treaty boundary data with other maritime datasets using the GDA94 coordinate datum for spatial analysis.
• Validate digital boundary representations against official treaty text for legal and diplomatic applications.

Strengths

• Official data product from Geoscience Australia, developed in consultation with the Attorney-General's Department and Department of Foreign Affairs and Trade.
• Includes the specific 2019 treaty ratification with Timor-Leste, providing current legal delineation.
• Coordinates are supplied in the GDA94 datum, operationally equivalent to WGS84 for broad compatibility.

Limitations

• The dataset is a digital representation only; the official treaty text prevails in case of inconsistency.
• Spatial coverage is limited to the specific region of the Australia-Timor-Leste boundary (approx. 9.5°S-11.5°S, 126°E-128.5°E).
• Data format is ESRI Geodatabase and Shapefile, requiring GIS software for full utilization.
