Elections were held in the state of New South Wales, Australia, on Saturday 19 September 1981. The result was a second "Wranslide": a landslide victory for the Labor Party under Neville Wran. Labor increased its already sizeable majority, winning what is still its biggest-ever share of seats in the New South Wales Legislative Assembly–69 out of 99 seats, 69.7 percent of the chamber. Ted Mack, mayor of North Sydney Council, won the seat of North Shore from Opposition Leader McDonald. John Hatton was re-elected unopposed in the seat of South Coast.
