 Considered a maverick, he was an ardent supporter of the mining industry, and crossed the floor on gold tax in 1988, and was also a vocal critic of the Mabo decision and sanctions on the apartheid regime in South Africa, and a proponent of uranium mining.In October 1993, and again in May 1995, he delivered a speech at the national seminar of the Australian League of Rights, a far-right group for which he was believed to hold sympathies, and in by-elections in Mackellar and Warringah (safe Liberal seats on the Northern Beaches of Sydney) in 1994, he urged electors to vote for Australians Against Further Immigration (AAFI).After numerous run-ins with the Labor leadership and considerable media attention to his exploits, he was finally expelled from the party on 30 November 1995 after addressing an AAFI meeting where he criticised Labor's immigration policies.
