Australia coach Eddie Jones bemoaned his side's mentality after the 24-22 loss to Wales, an eighth loss in nine.
"We've fallen into a hole after four good wins early in the year," he said.
"We're creating opportunities but not finishing them, it's becoming a habit. Wales had one turnover chance second half and they got the decisive try.
"Our stats are poor and I take full responsibility, but I'm not concerned about my job, I don't decide my future. I've done things to develop the side."
Jones' position has come under heavy criticism and many feel he is about to be shown the door my Australia.
Also under threat is captain George Gregan, who skippered the side for the 50th time in the game in his 118th cap - but was hauled off for Chris Whitaker early in the second half.
"Don't ask me whether I'm going to the 2007 World Cup, I don't think that far ahead of myself," Gregan told BBC Sport Wales after the game.
"That's a long way away, I'm concentrating on my time off and the next Super 14 season right now.
"The key thing about rugby is that you're enjoying it and contributing to the team you're in.
"The team's very disappointed, we wanted to end the season well to reflect all the hard work we've done.
"We had the perfect start to the second half and had plenty of chances to win, but we weren't good enough to take them.
"The scrum was under pressure and we have to work on that, but the penalty try was a big call from referee Tony Spreadbury.
"There were chances after that we should have taken, though, our performance and the result was disappointing.
"I do feel that we have brought on young players this tour and that we will learn and grow as a group from the experience."
