Central Coast Mariners will be the first A-League club to have a full complex at their disposal. In association with the Wyong RSL and Mariners Trust, a $40million complex will be built in Tuggerah including seven full-sized fields, a boutique stadium, five smaller fields and a 120-room accommodation block.

The complex will also have a six-storey administration building, sports science block, indoor aquatic centre, world class gymnasium and a 400-capacity function centre.

Trust chairman Peter Turnbull says the development presents endless possibilities.

"It will be ... where rival A-League clubs, plus international teams, can stay and train,'' he said.

"Our national youth league team and Westfield women's team will play competition games at the boutique stadium.

"It is a great union of two community-minded organisations that will now create a magnificent community asset,'' Turnbull concluded.
