The Government of South Australia has announced the official opening of a new AU$100m (£65.1m, EUR72.7m, US$108.5m) aquatic centre and leisure complex in Marion.

YMCA has been appointed to operate the South Australia Aquatic and Leisure Centre, which was unveiled on 9 April by state premier Mike Rann. Candetti Construction started work on the 26,400sq m (284,167sq ft) venue in October 2009, with a GP Plus Health Care facility also part of the complex.

The 10,000sq m (107,639sq ft) Aquatic and Leisure Centre features a 52m swimming pool; a 55m water polo and diving pool; and fixed and springboard diving platforms. Facilities also include two thermal hydro spas; a polar-chilled hydro spa; a sauna; a steamroom; two waterslides; and a group fitness studio, as well as a health club due to open in July.

More than 40 pieces of cardiovascular machines and 24 pieces of resistance equipment will be on offer in the health club, along with group fitness pieces and the TRX suspension system. The complex also boasts environmentally-sustainable measures, such as rainwater harvesting for re-use in toilet amenities and solar panels for the heating of hot water.

Rann said: "It will provide the facilities to nurture our stars of the future as well as a place for the community to learn to swim, get fit and enjoy a fabulous centre."
