The Marshall Liberal Government is committing $33 million to building a desalination plant at Kangaroo Island which will provide a new secure drinking water supply, unlock economic activity and improve bushfire resilience.

The 2 megalitre per day seawater desalination plant will improve drinking water security and provide better water infrastructure to support the local tourism and agriculture industries.

Premier Steven Marshall said this investment will create an estimated 500 jobs and add over $200 million of economic value to Kangaroo Island in the next 15 years.
