Global construction company Multiplex has been chosen to deliver Western Australia's COVID-19 dedicated quarantine facility.
Following the finalisation of feasibility studies and negotiations, the centre will be built at a site on Commonwealth-owned land within the Bullsbrook training area.
It will be constructed and owned by the Commonwealth, but will be operated by the WA government during the pandemic.
Finance Minister Simon Birmingham said it would initially be used to safely return travellers into Australia but would later be available for use in natural disasters or future health crises.
It is expected the first 500 beds will be operational in the first quarter of 2022.
