ASIO and the Department of Foreign Affairs and Trade. The Favaro Affair During the lead up to Indonesia's invasion of East Timor in 1975, the Australian Secret Intelligence Service (ASIS) paid a Dili-based Australian businessman Frank Favaro for information on local political developments. The leaking of his identity in late 1975 was another factor in the confrontation between Whitlam and Robertson. Bill Robertson disputed the reason for his dismissal in documents lodged with the National Archives in 2009. The Sheraton Hotel incident On 30 November 1983, ASIS garnered unwanted negative attention when a training operation held at the Sheraton Hotel, now the Mercure (Spring Street), in Melbourne went wrong. The exercise was to be a mock surveillance and hostage rescue of foreign intelligence officers. In March 1983, ASIS had begun training a covert team of civilians, including a female, at Swan Island in Victoria whose role was to protect or release Australians who may be threatened or captured by terrorists overseas.

When ASIS operators were refused entry into a hotel room, they broke down the door with sledgehammers. The hotel manager, Nick Rice, was notified of a disturbance on the 10th floor by a hotel guest. When he went to investigate, he was forced back into the lift by an ASIS operator who rode the lift down to the ground floor and forcibly ejected Rice into the lobby. Believing a robbery was in progress, Rice called the police. When the lift started returning to the ground floor, ASIS operators emerged wearing masks and openly brandishing 9mm Browning pistols and Heckler & Koch MP5 submachine guns, two of them with silencers. They forced their way through the lobby to the kitchen, where two getaway cars were waiting outside the kitchen door. Police stopped one of the cars and arrested the
