The official at the centre of the controversy, Craig Joubert, has been accused of robbing Scotland of a semifinal appearance - and was hung out to dry by World Rugby, who said following a review he should not have awarded the decisive penalty, from which Bernard Foley kicked the match-winning goal.
The media interest has led to numbers doubling for Cheika's press conferences at their tranquil base in south London.
But assistant coach Stephen Larkham said it hadn't been difficult to help the players refocus ahead of Argentina.
"Its been dealt with by Cheik and we back Cheik's decision there," he said. "We've had a review on Scotland, not reviewing anything else outside the game.
"Just our performance against Scotland and we're moving on to Argentina.
"There's too much work to be done to worry about what happened on the weekend." Cheika admitted the Wallabies were guilty of hanging on to their impressive pool wins over England and Wales, rather than switching focus to the all-important quarter-final against Scotland.
After using up their get-out-of-jail card, he took responsibility for the lapse and said he wouldn't let it happen again.
