Brian Austin

In 1983, Austin switched to the National Party (along with Don Lane, who was the Transport Minister, after Premier Joh Bjelke-Petersen lobbied several Liberals to cross the floor, thus enabling the National Party to form government with a very slim majority.

In 1987, Austin was one of three ministers who told Governor Walter Campbell that Bjelke-Petersen no longer had enough support to govern.

That was a precursor to the caucus coup that saw Bjelke-Petersen deposed as premier later that year.

Austin was subsequently implicated in the corruption being investigated by Fitzgerald Inquiry and was forced to retire in 1989.
