A by-election was held for the New South Wales Legislative Assembly seat of Davidson on 2 May 1992. It was triggered by the resignation of former Liberal Party-turned Independent MP, Terry Metherell, after the scandal known as the 'Metherell Crisis'. The seat was subsequently won by Andrew Humpherson of the Liberal Party. However the Liberals suffered a 16% drop in their primary vote, and a 14% drop in their two party preferred vote.
