Winger Sean Maitland and hooker Fraser Brown have been brought into Scotland camp ahead of their Wallabies clash.
Maitland and Brown have both been recovering from injuries, but will be in the mix to face the Wallabies when the sides meet at Murrayfield on Sunday morning (AEDT).
Brown was influential in Scotland's win over Scotland in June, and will return from an ankle injury to train with Scotland.
Maitland was struck down with a rib injury during the Six Nations and then injured his knee during his club season with UK team Saracens.
Scotland pushed New Zealand all the way at Murrayfield last weekend, falling just short of the world number one side.
Australia takes on Scotland on Saturday November 25, kicking off at 2:30pm local, Sunday 1:30am AEDT, LIVE on beIN Sports and SBS Viceland.
