The Australia–East Timor spying scandal began in 2012 when the Australian Secret Intelligence Service (ASIS) was revealed to have planted covert listening devices in the cabinet office of East Timor in 2004, with the purpose of gathering top secret information related to bilateral negotiations over the Greater Sunrise oil and gas fields in the oil rich Timor Gap.
 "Witness K", a former senior ASIS intelligence officer who was in charge of the bugging, provided information in 2012 which publicly revealed that the Australian Government had gained the top secret knowledge and used it during negotiations over the Treaty on Certain Maritime Arrangements in the Timor Sea (CMats).
 This treaty put a 50-year hold on East Timor's pursuit of expanded underwater territory, an area that has an estimated $US40 billion in oil and gas reserves.
 East Timor now disputes the validity of the treaty.
