A by-election was held for the New South Wales Legislative Assembly electorate of Port Stephens on 5 November 1988 because the Court of Disputed Returns declared that the 1988 Port Stephens election was void because Bob Martin handed government cheques to community groups during the campaign and this amounted to electoral bribery.
