A treetop walk, zip-lining, a hang-gliding simulator and cable-car network would be added to Cleland Wildlife Park under a new proposal by the state government.

The plans, which were developed by Hong Kong-based consultants Lan Kwai Fong Group, also include a hotel, “Australiana shopping village”, Kaurna cultural experiences and scenic restaurant and bar options.

The redevelopment aims to recast the Adelaide Hills nature park as a world-class tourism destination. But it’s not a done deal yet. The government will soon begin looking for a private investor and viable design scenarios to bring the vision to life.

“Cleland will always be a wildlife park, but has huge potential to be taken to the next level with some amazing new features to add a real wow factor,” Premier Jay Weatherill said in a press release.

“There are exciting opportunities here for private investors to be part of a sensational project that will take Cleland into the future as a must-visit destination.”

The redevelopment is likely to cost $150 million, the ABC reports.

Sustainability, Environment and Conservation Minister Ian Hunter said Cleland’s “unique animal interactions” – bringing visitors up close to local wildlife such as koalas, kangaroos and wallabies – would always be a key feature of the park.

“Adding exciting new offerings – like a cable car, a soaring simulator, world-class dining and nature play spaces … will take the park to the next level and make it a magnet for visitors from all over the world.”

Premier Jay Weatherill unveiled the plans yesterday, four months out from the state election.
