Lyon, France –

Eddie Jones said he remained 100% committed to the task of turning Australian rugby around after his young side was demolished by Wales and pushed to the brink of elimination from the World Cup in the pool stage on Sunday.

Jones was hired on a five-year contract in January, but a report in the Sydney Morning Herald on Sunday cited sources as saying he was interviewed about returning to the Japan job when Brave Blossoms coach Jamie Joseph leaves after the World Cup.

"I don't know what you're talking about, mate," he said when questioned about the report after the 40-6 loss to Wales.

"I came back to Australia to try to help as much as I can. I'm a proud Australian. I hate to see Australian rugby do as poorly as we've been doing, particularly under my reign.

"There's not only the Wallabies we've got to try and improve, we've got to improve the whole system of Australian rugby.

"That's not an excuse. We've got to have a really good look at ourselves, and to continue improving and getting better."

Jones bristled after continued questioning over the report and threatened to walk out of the post-match news conference.

"I really take umbrage at people questioning my commitment as Australia coach," he said.

"I've been working nonstop since I've come in and apologize for the results. But to question my commitment to the job I think is a bit red hot."

Rugby Australia chief executive Phil Waugh told reporters in Lyon that Jones had assured his employers there was no foundation to the report.

"You just have to take people for their word," the former Wallabies flanker said.

"He said he hasn't, and if he has, that's something that we'll deal with at the time that becomes evident."

Jones previously coached Japan for three years from 2012 and led the Brave Blossoms to a stunning upset of South Africa at the 2015 World Cup.

The 63-year-old was sacked after seven years as England coach last December and returned to Australia for his second spell in January.

Jones proclaimed that Australia would win the World Cup for the third time with a "smash and grab" raid in France, but results have so far failed back up his hyperbole.

After losing all three matches in the Rugby Championship and the second Bledisloe Cup test against New Zealand, the Wallabies were trounced 41-17 by France in their final warmup for the World Cup.

Australia opened its campaign with a 35-15 win over Georgia but lost to Fiji for the first time in 69 years in its second match in Pool C last week, leading to a barrage of criticism of Jones' decision to trust in youth for the World Cup.

"We're disappointed, they're a young team and they're very disappointed, they tried their hearts out," he added on Sunday.

"And, of course, at the moment we just don't have the consistency in our favor to put pressure on teams like Wales.

"The only way you get experience is by playing these games and sometimes you know, games like this have the makings of a good team going forward."
