Australian hospitality operator The Star Entertainment Group has designed a masterplan for a multi-billion dollar “globally-competitive integrated resort” on the country’s Gold Coast.

The group is working with the City of Gold Coast Council and Queensland State Government to significantly expand an existing hotel and casino property, called Jupiters, located on Broadbeach.

At the heart of the proposal is a new 200m (656ft) tower, featuring luxury apartments and a 700-room 4.5 star hotel.

In addition, the company plans to create up to five new hotel buildings, entertainment facilities, tropical gardens, pools and spa, and a recreational deck.

These additions would follow another new tower, which has already been approved and is under construction. Featuring a six-star hotel, that building will be 17-storeys high when completed. A full refurbishment of Jupiters’ 600 existing hotel rooms is also taking place.

If the proposed tower is approved by planners, the whole redevelopment project will be worth up to AUS$850m (US$622.5m, €550m, £430m), in addition to the millions of dollars already spent on the resort.

The architects and engineers who would create the new tower have not been revealed.

“This proposed masterplan concept is about building on the exciting tourism forecasts we are seeing for the Gold Coast, with much-needed new infrastructure to deliver an international world-class integrated resort on the coast without the need for any additional poker machines,” said Star Entertainment Group managing director and CEO Matt Bekier.

The group’s MD for Queensland, Geoff Hogg, added: “The masterplan creates a seamless flow between phased developments to provide the ultimate dining, retail, recreation and gaming experiences.

“It would ensure our current projects complement and support our longer-term investment plans, with overall design that achieves the right mix of accommodation and leisure offerings, and also importantly improves connectivity throughout the local Broadbeach precinct.”

Public information sessions will be held from now until 9 June 2016 to inform the community about the masterplan. If the masterplan is approved, construction on the new tower could commence in 2017 on the ocean side of the existing property.
