Half Tide Beach is a coastal suburb immediately south of Hay Point and 20 km south of central Mackay. It is unrecorded in the Queensland Place Names Register, but it existed at least as far back as the late 1950s: the 1961 census recorded Half Tide Beach as a holiday spot with 45 dwellings, all unoccupied on census night and no resident population.

Half Tide Beach is a dormitory suburb for the Hay Point coal terminal. In the last census that it was recorded (2006) 37% of employed persons living at Half Tide Beach were technicians and machinery operators, compared with 21% for Australia.
