The Victorian Desalination Plant (also referred to as the Victorian Desalination Project or Wonthaggi desalination plant) is a water desalination plant in Dalyston, on the Bass Coast in southern Victoria, Australia, completed in December 2012. The plant is an integral part of Victoria's water system, supplying water via a series of existing and proposed pipelines. As a rainfall-independent source of water it complements Victoria's existing drainage basins. It is a useful resource in times of drought. Booked tours are run and plans are underway for Aquasure to open to the public. The gates open daily for public access to the 225 hectare park and 8 kilometres of walking, horse riding and cycling tracks. The plant is located next to Williamsons Beach and the Wonthaggi Wind Farm, Wonthaggi.
