Australia will be without Michael Hooper to take on Wales in the Pool of Death decider after the openside was handed a one-week ban.
Hooper was found guilty of an illegal cleanout on Mike Brown in their 33-13 win over England at Twickenham last weekend.
Hooper was penalised by referee Romain Poite but he was cited by citing commissioner Steve Hind.
A guilty plea and clean record reduced the ban from two to one week meaning the Waratahs captain will be available for the quarter-finals.
