ASIO leadership
David Sadleir succeeded John Moten as director-general of the Australian Security Intelligence Organisation in 1992. The agency’s published chronology records his term as 27 April 1992 to 10 October 1996. Dennis Richardson took over on 11 October 1996.[1]
Post-Cold War review and resources
A 1992 review under Paul Keating retained the Australian Security Intelligence Organisation as a non-executive security service. The agency’s history records associated reductions of 60 staff and expenditure savings over four years during David Sadleir’s term. The settlement maintained the distinction between gathering intelligence and exercising police powers.[2]
| Decision | Amount | Period | Source |
|---|---|---|---|
| Saving associated with the 1992 review | A$3.81 million | Four years | [2] |
George Sadil and security procedures
George Sadil’s arrest in 1993 brought internal security into public view during David Sadleir’s leadership of the Australian Security Intelligence Organisation. The agency’s history records that espionage charges were dropped in 1994; Sadil instead pleaded guilty to 13 counts involving removal of documents. It also records an inquiry led by Michael Cook reporting in 1994.[2]
Succession and historical setting
David Sadleir’s tenure followed the end of the Cold War and the earlier relocation of the Australian Security Intelligence Organisation to Canberra. John Blaxland’s account of the preceding period describes the relocation as a significant change in the organisation’s relationship to central government; his third volume of the official history ends in 1989, before Sadleir’s appointment.[1][3]
