Malcolm Fraser was a conservative prime minister of Australia from 1975 to 1983. Although he is from the same political party as the current Prime Minister John Howard, he has become a strong critic of Howard's and an activist for refugees through organisations such as A Just Australia (http://www.ajustaustralia.com/whoweare_whatwedo.php)
He started an on-line petition against the government's current policy of locking refugee children in detention, and of separating families from each other (http://www.petitiononline.com/dtention/petition.html) and has also shown support for reconciliation between Aboriginal and non-Aboriginal Australians. http://www.racismnoway.com.au/classroom/Factsheet/46.html
He has also criticised George Bush for interfering in Australian politics, and has described this as an abuse of Bush's power. (http://www.theage.com.au/articles/2004/06/06/1086460170824.html )
