After five years of planning, a proposal from Perth hospitality group The Prendiville Group to build a luxury resort on Rottnest Island has been approved by the Rottnest Island Authority.

Estimated to open in late 2020, the $30 million, 80-room resort – designed by Christou Design Group (City Beach Surf Club, Allendale Square, Scarborough Beach Pool) – will feature suites, and beachfront villas with private pools.

Other facilities in the resort will include two pools, a gym, a day spa and the island’s first outdoor rooftop bar.

Prendiville Group chairman Peter Prendiville says the project will have a strong focus on sustainable design; it will use renewable energy and minimise waste.

The as-yet-unnamed resort is being built adjacent to the existing Hotel Rottnest. Although Hotel Rottnest’s 18 rooms have been closed to the public, the hotel’s existing bar and restaurant will continue to trade during construction.

The development is the latest hotel project for the Prendiville Group following a recent reboot of East Fremantle’s historic Tradewinds Hotel. The group also owns the Cottesloe Beach Hotel, Broome’s Mangrove Hotel and Sandalford Winery in the Swan Valley.

The resort is the second major Rottnest Island development to be announced in as many months following news in April that the island is getting a new eco retreat.

The new Rottnest Island resort is expected to open in September 2020.
