Treaty on Certain Maritime Arrangements in the Timor Sea

Officially called the Treaty between Australia and the Democratic Republic of Timor-Leste on Certain Maritime Arrangements in the Timor Sea (CMATS), the treaty provides for the equal distribution of revenue derived from the disputed Greater Sunrise oil and gas field between Australia and East Timor. The field is located in the Timor Gap where Australia and East Timor have overlapping claims over the continental shelf or seabed.
