We discuss with the South Australian environment and water minister why the government intends to proceed with a desalination plant in Boston Bay despite an independent site selection committee commissioned by the former Marshall Liberal government preferring Sleaford Bay on the southern Eyre Peninsula. We cover SARDI's research on the environmental impacts in Boston Bay, how a future desalination solution at Whyalla could interface with the Eyre Peninsula's water security needs, and what prospects there are in future for more desalination for instance for West Coast communities.
