The Parliament of Australia member page for Hon Alexander Downer AC is the identity anchor. It records birth on 9 September 1951 in Adelaide; a B.A. (Hons) from the University of Newcastle upon Tyne; service in the Australian Diplomatic Service from 1976 to 1982; a political-adviser role to Prime Minister Malcolm Fraser in 1982–83; and a director role at the Australian Chamber of Commerce (A.C.T.) in 1983–84.
The same official page records election to the House of Representatives for Mayo, South Australia, on 1 December 1984; re-election in 1987, 1990, 1993, 1996, 1998, 2001, 2004, and 2007; Liberal Party service from 1 December 1984 to 14 July 2008; and resignation on 14 July 2008. Those are parliamentary facts. They are not a Crossfire Hurricane finding.
The page also lists him as Leader of the Opposition and Liberal leader from 23 May 1994 to 30 January 1995, and as Minister for Foreign Affairs from 11 March 1996 to 3 December 2007. King’s College London’s faculty line repeats the foreign-minister and opposition-leader dates. No second equally notable public Alexander Downer was located for this file.
