The Portuguese colonial administration granted concessions to the Australia-bound Oceanic Exploration Corporation to develop petroleum and natural gas deposits in the waters southeast of Timor. However, this was curtailed by the Indonesian invasion in 1976. The resources were divided between Indonesia and Australia with the Timor Gap Treaty in 1989. East Timor inherited no permanent maritime boundaries when it attained independence. A provisional agreement (the Timor Sea Treaty, signed when East Timor became independent on 20 May 2002) defined a Joint Petroleum Development Area (JPDA) and awarded 90% of revenues from existing projects in that area to East Timor and 10% to Australia. An agreement in 2005 between the governments of East Timor and Australia mandated that both countries put aside their dispute over maritime boundaries and that East Timor would receive 50% of the revenues from the resource exploitation in the area (estimated at A$26 billion, or about US$20 billion over the lifetime of the project) from the Greater Sunrise development. In 2013, East Timor launched a case at the Permanent Court of Arbitration in The Hague to pull out of a gas treaty that it had signed with Australia, accusing the Australian Secret Intelligence Service (ASIS) of bugging the East Timorese cabinet room in Dili in 2004. East Timor is part of the Timor Leste–Indonesia–Australia Growth Triangle (TIA-GT).
