Wallabies coach Michael Cheika says he knew he would leave his role after quarterfinal defeat to England.

Wallabies great Nick Farr-Jones believes voluntary administration is the likely next step for the embattled Rugby Australia.

While backing former teammate Phil Kearns to take over as RA boss and eventually help the game return to its former glory, Farr-Jones could only see short-term pain for the cash-strapped code.

"I wouldn't be surprised if an administrator was appointed in the next fortnight," Farr-Jones told ABC radio program The Ticket on Sunday.

STUFF Former Wallabies captain Nick Farr-Jones says the money has nearly run dry at head office in Sydney.

"I understand that reserves are minimal ... that would only be funds that have come from world rugby from the participation rights of the World Cup last year.

"Otherwise I just don't think we've put any acorns away for a winter like we're expecting at the moment where there's no income projected."

GETTY IMAGES Phil Kearns, pictured at last year's Australian Open, has backing to take over at the helm of Rugby Australia.

RA said on Sunday night it had made good progress in negotiating an emergency interim pay deal with the Rugby Union Players' Association (RUPA), as it sought to reach an agreement on salary cuts, forced by the coronavirus pandemic and preventing games being played.

Backing up his comments from an interview on Saturday, Farr-Jones said while he wasn't privy to all of RA's financials he would be concerned about the going concern issues, with the business still facing a large wage bill for players.

"If you have going concern issues and you don't want to breach the corporations act, well then you go into voluntary administration."

SYDNEY MORNING HERALD Rugby Australia chief executive Raelene Castle is under increasing fire from former Wallabies.

Farr-Jones, who earned 63 caps over 10 years, said incumbent CEO Raelene Castle had inherited problems when she was appointed to the position in 2017.

But he felt she also lacked experience and criticised her handling of the costly Israel Folau case and current broadcasting negotiations.

That was where he felt Kearns, currently a Fox Sports commentator, could do better.

"You have to have a deep knowledge of the game to take on the role; you have to understand intricately who the people are in world rugby, intricately about the community game and you can't be learning on the job.

"Phil Kearns has got three and a half decades of being intricately involved in the game.

"He knows people, he's trusted by people and he'd been in broadcasting for a long time and that's the most important thing RA has to lock away.

"He would be great with securing sponsors and with fans - we need the rusted on rugby people we've lost to come back to the game."

Working in mining finance, Farr-Jones said he would consider a seat on the board: "I'd like to come back on board passionately for the game."

Among other changes Farr-Jones felt were needed was a cut of at least 50 per cent in staff numbers at RA and also incentive-based contracts for players.

"I would put them on contracts with a good base salary but a minimal one with incentivisation - you guys win and we'll pay you well.

"I understand there's a lot of money in Europe and Japan but my strong view is if you want to take that money and give up the opportunity to pull on the gold jersey then do it.

"They are the tough decisions that are needed to get the culture of the game back."

RUPA CEO and former Wallabies lock Justin Harrison said on Saturday it might take a week or longer to reach a pay agreement, given what had transpired in other codes on the same issue.

Last week, RUPA had complained it had not been given access to financial information before previous meetings with RA.

"Rugby Australia remains focused on securing a fair and reasonable deal with the players that will help protect the long-term future of our game," Castle and RA chairman Paul McLean said on Sunday in a statement.

"We also welcome recent comments by World Rugby as it assists all national unions navigate through this very difficult time."

"The players understand that the burden must be shared by everyone in our game and we will look to reach an agreement which is fair and reasonable given the extraordinary circumstances we are in."
