Australia-Timor-Leste Maritime Boundary Treaty Data 2019

Geoscience Australia provides a digital representation of the maritime boundary treaty ratified between Australia and Timor-Leste on 30 August 2019. The data covers a geographical extent between approximately 9.5°S to 11.5°S latitude and 126°E to 128.5°E longitude and uses the GDA94 datum. It is published as part of the 2019 epoch of the Australian Maritime Boundaries database.

Use Cases

• Visualizing the agreed maritime boundary between Australia and Timor-Leste based on the treaty coordinates.
• Integrating treaty boundaries into maritime spatial information systems (e.g., AMSIS) for jurisdictional analysis.
• Supporting legal and diplomatic discussions by providing a digital reference for the treaty limits.
• Conducting maritime zone calculations for resource management or environmental regulation based on the defined boundary.

Strengths

• Data represents a formally ratified international treaty, providing an authoritative legal reference.
• Geographical extent is precisely defined with latitude and longitude limits.
• Data is published by Geoscience Australia in consultation with other key Commonwealth agencies.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset includes a disclaimer that the treaty text prevails over the digital representation in case of inconsistency.
