The hearing into a proposed luxury resort at Cape Bridgewater will be held in May.
The Priority Projects Standing Advisory Committee hearing will begin on Wednesday, May 26.
The hearing into whether the $85 million eco resort should be approved is expected to last 12 days.
The proposed resort would include an 88-bedroom hotel spread over four lodges as well as 13 two-bedroom and five one-bedroom villas.
The hotel will be connected by a tunnel to a restaurant with sweeping views across the bay and will also include a spa, gallery and underground car park.

Glenelg Shire councillors voted 6-1 to give "in-principle support" to the project and referred it to the planning minister Richard Wynne to make the final decision.
A GoFundMe page by residents concerned about the large-scale development has raised more than $6000.
One of the residents, Mary Picard, grew up in the area and believes the proposed hotel would destroy the bay's unique beauty.
