Timor Gap

The Timor Gap is an area of the Timor Sea between Australia and Timor-Leste. The area has been the subject of disputes over maritime boundaries, as well as the rights to extract and take revenue from its substantial petroleum reserves.

Australia and Portugal initially disputed the area when the latter governed East Timor. After the Indonesian occupation of East Timor, a joint development zone was created between Australia and Indonesia, which largely persisted after Timor-Leste achieved independence and took Indonesia's place in its administration. The maritime boundary between Australia and Timor-Leste was settled in 2018.

The Timor Gap is part of the Australia–Timor-Leste border, Australia–Indonesia border, and Indonesia–Timor-Leste border. It is 480 km (300 statute miles) wide.
