Rugby League fans in New South Wales will secure the world-class facilities they deserve under the new stadium program unveiled by the NSW Government today.

NRL CEO Todd Greenberg said the decision to build new stadia at Sydney Olympic Park and Moore Park – in addition to the new Western Sydney stadium at Parramatta – is the breakthrough the game needs to draw more people to matches.

"Our fans will now have access to three world-class stadia where they can watch anything from Telstra Premiership games through to State of Origin and Grand Finals," he said.

"Those games will be held in rectangular venues, purpose-built for rugby league with fans able to sit closer to the action than ever before.

"It's a great result for our clubs, for our fans and for the game."

Mr Greenberg said the NRL would now commit to keeping the Grand Final in Sydney for the next 25 years.

One Grand Final is likely to be staged at the Sydney Cricket Ground while ANZ and Allianz Stadiums are under construction.

Mr Greenberg said at least one State of Origin match will also be held in Sydney each year for the length of the agreement.

"We have always said that if the NSW Government is going to spend billions of dollars on new venues, then we will commit to using those facilities for our biggest events," he said.

The NRL has signed a new Memorandum of Understanding with the NSW Government pledging to keep the Grand Final in Sydney as long as the timeline for construction of the new stadia is met.
