Wallabies coach Dave Rennie made it plain that he believes Australia must remain involved in Super Rugby Pacific.
His comments come after the reported comments of Rugby Australia chairman Hamish McLennan that Australia would commit to the competition until the end of 2023 but would then look to what was best for Australia ahead of its staging of the 2027 Rugby World Cup.
Rennie, who coached the Chiefs to two Super Rugby titles in 2012 and 2013, urged Australia not to pull out of the competition.
He said Rugby Australia should continue in the competition and set up an Australian domestic competition as a lead-up to the World Cup.
"I've made it pretty clear in the past I think it's good for both countries that we play trans-Tasman footie," he said.
"I think the competition has been excellent this year, and our sides have certainly been more competitive. It's good for them, it's good for us, and I'd like to see that continue.
"They've got some of the best players in the world. You want to be playing the best players. That's how we will get better and be challenged, so it's important," he said.
At the same time, South African coach Alan Solomons told rugbypass.com, in a retirement interview, that he believed the Springboks should remain a southern hemisphere competitor.
"I'm a bit old-fashioned. I'm of the view we're a southern hemisphere power, and we need to be with New Zealand and Australia. And that's good for world rugby.
"I don't think it's good for world rugby to have that link broken. The northern hemisphere is very powerful on its own," he said.
Solomons, 72, ended his career with Worcester Warriors in England. He said he understood the commercial value and time benefits of playing in Europe for clubs but was a traditionalist about Tests.
"New Zealand are our opponents, like England v Scotland. I remember as a 10-year-old boy in 1960, after the third [sic - should be first] Test that we won 13-0, I went to get the paper for my dad.
"Virtually the entire Sunday paper was the rugby Test. The whole paper. Your whole life was around that. The All Blacks-Springboks games, those are massive for both teams," he said.
