Australia have called up scrum-half Jake Gordon as injury cover for Will Genia for the third Test against Ireland.
Genia was forced off with a broken arm in the 27th minute of Saturday's 26-21 defeat to the Irish in Melbourne that tied the series at 1-1.
The 30-year-old playmaker had surgery on the injury on Sunday and will be sidelined for six weeks.
Nick Phipps is likely to come into the starting line-up for the series decider in Sydney.
