Ballymore Stadium has been reserved for the possible launch of an annual rugby union State of Origin clash between Queensland and NSW.

Rugby union's key stakeholders are behind the idea driven by Queensland Rugby Union chief executive Richard Barker and NSW counterpart Andrew Hore.

It is designed to give the sport some quality domestic content during Super Rugby's mid-season international break.

The Australian Rugby Union, Rugby Union Players' Associaton and all five Super League franchises have endorsed it while Wallabies skipper Stephen Moore believes it is a concept "worth exploring".

There is even the ideal gap at the end of next year's June Test window that would make Australia's stars available.

The match has been tentatively pencilled for Friday, June 30 - a week after Australia meets Italy at Suncorp Stadium in Brisbane.

Negotiations are ongoing, but the QRU have taken the additional step of booking Ballymore for that week to ensure the venue is ready to host the match - dubbed 'State of Union' - if it comes off.

"We think given the unique history of Ballymore that hosting the inaugural game here would add to the spectacle," Barker told AAP.

"We envisage a festival of rugby that day which would include curtain-raisers that speak to the breadth of our code across all forms of rugby.

"The response in the rugby community to the concept of State of Union games has been encouraging ... (but) these are early days.

"I note Stephen Moore's supportive comments overnight and previous comments from Bill Pulver and other CEOs and we will continue to discuss this concept with all of rugby's stakeholders."

Ballymore may require a minor upgrade to be ready, which would fill the stadium to its 18,000-seat capacity.

But it's understood the QRU is working feverishly behind the scenes on the future of the precinct, which has long needed a full redevelopment and is under increasing demand from local sporting bodies.

A-League side Brisbane Roar trains out of Ballymore while two overseas teams will hold a pre-season warm-up matches there in the lead-up to the Brisbane Global Tens tournament.
