A proposal by Queensland to host rugby union's first state of origin game in next year's mid-season Super Rugby break is reportedly being considered by NSW.
Waratahs flanker Michael Hooper and Reds hooker James Hanson dont see eye to eye.
But the clash would likely be minus Australia's best players, who would be on international duties during the June Test window.
Administrators are concerned the code is losing momentum at a crucial time during the crowded winter sports schedule, when the provincial competition comes to a month-long halt.
NSW fullback Jarryd Hayne scores over Maroons centre Greg Inglis.
"All of a sudden we come to a dead stop at a time when rival codes are building to the high point of their seasons," Queensland Rugby Union boss Richard Barker told News Corp Australia.
"Let's play a state of origin match at Ballymore. It's a rugby-owned ground, so rugby would get all the proceeds."
The Waratahs are open to the concept, but chief executive Andrew Hore expressed a need to liaise with the Australian Rugby Union and Sydney's Shute Shield clubs.
"We applaud the initiative and we're certainly open for discussion," Hore told News Corp.
"An origin game does highlight the fact that the vast majority of professional rugby players in this country come from NSW and Queensland and sometimes it doesn't hurt to mention that.
"There is no question, too, that we are looking at the June window very carefully."
Waratahs coach Daryl Gibson said the concept could have significant benefits for Australian rugby.
"The problem we need to solve in Australia is getting enough rugby," the New Zealander told Sky Sports Radio on Friday.
"That's what the administrators are talking about - in that period where Super Rugby takes a break and the international games take over - is finding some really relevant that people will want to watch.
"I'd be definitely one who would look at it."
