Australia head coach Eddie Jones on Sunday apologised for the Wallabies' record defeat to Wales but insisted he was "committed" to the job.
"I would like to apologise to all Australia supporters," said Jones after the 40-6 Rugby World Cup thrashing.
Australian media reports claimed Jones has been interviewed by the Japanese federation about taking over their team after the tournament.
"I don't know what you're talking about, mate," said Jones, when probed about the alleged interview, before later adding he took "umbrage" with those questioning his commitment.
"One hundred percent," he said when asked if he was committed.
"I came back to Australia to try to help. At the moment I'm not getting much help, am I.
"But that doesn't mean my commitment to help has changed. I'm a proud Australian and I hate to see Australian rugby doing as poorly as we're doing, particularly under my reign."
Australia have lost seven out of their eight matches since the 63-year-old returned to the helm for a second stint as national team boss.
They reached the 2003 World Cup final in his first one.
But Jones said there was more to fix in Australian rugby than just coaching issues or underperforming players.
"It's not only the Wallabies we've got to improve, we've got to improve the whole system of Australian rugby," he said.
"That's not an excuse but we've just got to have a really good look at ourselves to see what we're doing and the way we're going about our rugby."
As for Sunday's debacle in Lyon, it was Australia's largest ever World Cup defeat as well as their biggest against Wales, surpassing a 28-3 reverse in 1975.
"First, I'd like to apologise to all Australian supporters," said a contrite Jones.
"A lot of people travelled here and I'm sure a lot of people were staying up late at night (in Australia).
"Our performance wasn't up to the standard that is required. I apologise and I take full responsibility for it.
"The are a young team, we're very disappointed. They tried their hearts out but at the moment we don't have the consistency in our play to put pressure on teams like Wales."
