The Wallabies have called up Brumbies captain Ben Mowen as cover for Western Force No. 8 Ben McCalman who has been struggling with a shoulder injury ahead of Australia's rugby test against Scotland on Tuesday.
Australia will name its team on Sunday for the Scotland match at Newcastle north of Sydney.
Six Nations champions Wales will play Australia on the following three weekends.
Mowen has previously represented Australia in under-21s and Sevens, but is uncapped in test play.
He led the Australia Conference-leading Brumbies to a 27-19 win over the Melbourne Rebels in a Super 15 Rugby match on Friday.
