destroyed all records. It appears, however, the last ASIS agent did not leave Chile until October 1973, one month after the CIA-backed 1973 Chilean coup d'état had brought down the Allende Government. There were also two officers of ASIO based in Santiago, working as migration officers during this period. It is one of two incidents that caused a confrontation between Whitlam and Bill Robertson, the director-general of ASIS, resulting in Robertson's sacking on 21 October 1975, with effect on 7 November, just four days before Whitlam's own dismissal in the 1975 Australian constitutional crisis. Whitlam said Robertson had disobeyed instructions by delaying the closure of the ASIS station in Chile in 1973 and not informing Whitlam that ASIS had an active agent in East Timor in 1975. Robertson disputes the details in a personal statement lodged with the National Archives in 2009. ASIS' involvement in Chile was revealed in 1974 when Whitlam set up the First Hope Commission to investigate Australia's security services. Whitlam told parliament that 'when my government took office, Australian intelligence personnel were working as proxies of the CIA in destabilising the government of Chile'. After the coup by Augusto Pinochet, Whitlam's government created a special program for Chilean refugees to come to Australia. Under the program, about 6,000 Chileans came to Australia between 1974 and 1981 and hundreds more joined them as part of a family reunion program. The National Archives of Australia holds documents related to ASIS operations to help the CIA undermine the government of Allende in the years 1971-1974. In 2021, the archives refused a request from Clinton Fernandes, professor of International and Political Studies at the University of New South Wales, to access records relating to ASIS operations in Chile. Heavily redacted versions of some documents were released to Fernandes in June 2021. The documents show that the ASIS base in Chile assisted the CIA's destabilisation of Allende's government by handling CIA-recruited Chilean assets and filing intelligence reports to CIA headquarters in Langley, Virginia. In November 2021, the Administrative Appeals Tribunal (AAT) upheld the archives' decision to reject Fernandes' request for access to the documents. The AAT said the release of documents would 'cause damage to the security, defence or international relations of the Commonwealth'. Most of the AAT hearing was held behind closed doors, because Attorney-General Michaelia Cash issued a public interest certificate, suppressing the disclosure of evidence provided by ASIS,
