McCaffrey is open to an Australian domestic competition including the Western Force should officials go down that path with Super Rugby halted by COVID-19.

The 30-year-old would have "no issue" starting from scratch despite the Brumbies' superb start to the Super Rugby season, adamant his side is only worried about lifting a trophy - whatever it may look like.

A domestic or trans-Tasman competition looms as the most likely option for 2020, with McCaffrey confident Australia has the depth of talent to sustain its own tournament.

It could be the key to drawing disillusioned fans back to the code.

"I think it's a great opportunity for Australian rugby to try something interesting, something new," McCaffrey said on The Rugby Nation Show.

"There has been a lot of negativity about the games against South African teams or Argentinian teams. As players, I've always loved touring over there and playing in some of the great stadiums you get to play in.

"I think the priority should be putting together a competition that the viewers really want to watch and get behind.

"If that's an Australian-only competition bringing the Western Force back in, then so be it. Let's have a crack.

"All we're worried about is winning whatever competition we're put back into. That was our goal since day one of pre-season."

Calls for Australia and New Zealand to break away and form their own competition may soon come to fruition if only for a season, with a trans-Tasman model likely should rugby be cleared to resume.

McCaffrey believes the majority of rugby fans "want to watch Australian derbies" so the chance to host more of them could put more bums on seats and eyes on televisions.

"You've got that affiliation, you've got that connection to the players you are actually watching on television. That's what I think is quite special in terms of Australian derbies," McCaffrey said.

"I think a lot of people get scared of having Australian derbies because they think 'it won't be as good quality as South African derbies or New Zealand derbies'. But I think it's rubbish, I wouldn't be worried having an Australian conference at all.

"At the end of the day the viewers and the supporters are the most important thing in our game. If they want to watch more Australian derbies, if they want to get behind an Aussie conference system, I would love to be playing in one.

"Winning a trophy to be the best in Australia, you would get just as much joy out of it as winning a different style by beating the Jaguares or beating a South African or New Zealand team too."
