The Liberals were originally a broad church, with its most salient feature being that its members were more likely to own property. The more socially moderate members (sometimes referred to as “wets”, a term borrowed from the British Tories) started dwindling in the long Howard era (1997-2007 and 2011-2022 or so) when the party pivoted to Murdochian culture-war conservatism, and eventually lost almost all their historic seats in wealthy suburbs, while outer-suburban party branches were taken over by religious groups (pentecostals and Mormons, IIRC)
