ConocoPhillips holds a significant acreage position in the Timor Sea Joint Petroleum Development Area (JPDA) between Timor-Leste and Australia, the site of the company's major Bayu-Undan development. The Bayu-Undan Offshore facility located in the Timor Sea sends gas, via a 502 kilometre subsea pipeline, to the Darwin Liquefied Natural Gas (LNG) plant to be converted to LNG for export to Japan.

Other exploration and development projects are located offshore Northern Territory and Western Australia, and include Greater Sunrise, Athena, Browse Basin, Caldita and Barossa discoveries. Onshore, in Queensland, the company has significant holdings in coal seam gas assets.
