Ospreys forward James King will train with the Wales squad at the start of this week ahead of the final November Test.
The 23-year-old made his international debut on the tour to Japan and was part of the 2013 Six Nations Championship squad.
King linked up with the squad on Monday as they gathered to prepare for Saturday's match against Australia.
The Australian-born lock will join a deep pool of locks currently in the Wales squad, including Alun Wyn Jones, Luke Charteris, Bradley Davies, Ian Evans and Andrew Coombs.
Wales are looking for a third consecutive win after defeating Argentina and Tonga earlier this month.
