Cairns Aquarium in Australia has been put up for sale, as the visitor attraction's directors seek fresh investment.

Commercial real estate agents, Colliers, have been appointed to manage the sale process, which the directors hope will attract "global interest".

The three-storey, 10,000sq m (107,600sq ft) aquarium is home to more than 5,000 animals.

First opened in 2017 by co-developers Daniel Leipnik and Andrew Preston at an estimated cost of AU$50m, the aquarium received substantial government funding and support throughout its development.

Designed by Peddle Thorp Architects, in association with Ellick & Partners, the building's exterior is made up of a series of 'tectonic plates' symbolising the movement of the earth and subsequent creation of the Great Barrier Reef and Northern Queensland's rain forest covered mountains.

Colliers said: "After six years in operation, with increasing profitable revenues and vigorous growth, the founding partners of Cairns Aquarium are seeking expressions of interest to become invested in this proven and successful business opportunity.

"It provides visitors with an educational and entertainment experience across more than 70 displays, showing casing the species, habitats, and ecosystems of tropical north Queensland."
