The Wallabies have moved up a spot to sixth in the latest World Rugby rankings.
Wales' win over Scotland pushed the Scots down to seventh, with the Wallabies moving up to sixth ahead of their Spring Tests.
Australia has been seventh in the rankings since the middle of September, after a loss to Argentina on the Gold Coast.
The Welsh have been ranked third in the world since June, after a strong Six Nations - their highest ranking since a no. 2 spot in the Rugby World Cup.
Despite their current rankings gap, Australia has been historically dominant over Wales, winning their past 13 Tests dating back to 2009.
Wallabies centre Kurtley Beale said that record didn't affect Australia coming into the clash.
