Timor in the place of Indonesia in the Timor Gap Treaty, except that the ratio of revenue distribution in the Joint Petroleum Development Area, known as the Zone of Cooperation under the 1989 treaty, was changed to 90:10 in favour of East Timor. The 2002 treaty provided for the future "unitisation" - treating a gas or oil field which straddles one or several borders as one unit - of the Greater Sunrise gas field, of which only 20% was located within the JPDA while the rest was deemed to be in Australian territory. In East Timor's view, this distribution could be disputed as it did not recognise the borders, drawn between Australia and Indonesia, which placed the bulk of Greater Sunrise in Australian territory. On 20 February 2007, East Timor's parliament agreed to ratify the agreement with Australia over the management of oil and gas resources in the Greater Sunrise field in the Timor Sea. The Australian and East Timor governments formally exchanged notes in Dili on 23 February 2007 to bring into force the two treaties that provided the legal and fiscal framework for the development of the Greater Sunrise gas field in the Timor Sea. The notes covered the Sunrise International Unitization Agreement (Sunrise IUA) and the Treaty on Certain Maritime Arrangements in the Timor Sea (CMATS). Foreign Minister Alexander Downer, using a power invoked only six times in its history, invoked a "national interest" exemption clause to fast-track ratification of the CMATS treaty through the Parliament without scrutiny by its Joint Standing Committee on Treaties. 2018 Maritime Boundaries Treaty On March 7, 2018, Australia and East Timor announced that a treaty had been signed regarding the border and the exploitation of the Greater Sunrise gas field. The agreed boundary would follow the median line between the two countries. The 2018 Maritime Boundaries Treaty formalized the agreement reached by Australia and Timor Leste on their maritime boundaries. The two countries had failed to reach agreement on a preferred option for development of the Sunrise/Troubadour field, and annexes to the Treaty set out procedures for achieving this. Article 3 of the 2018 treaty on maritime boundaries between Australia and Timor-Leste provides for adjustment of the continental shelf boundary between the two countries following settlement of that boundary between Indonesia and Timor-Leste. If those countries agree to an endpoint to their continental shelf boundary west of point A18 on the
