The Wallabies, who have lost to Wales and Fiji, look to be heading out of the tournament after Fiji came from behind to claim a narrow win over Georgia on Saturday.
There are major questions around the state of Australian rugby and there is little doubt Jones is fighting for his job.
While minnows compared to Australia, Portugal have won plenty of admirers for their attacking style in France and must be licking their lips at the prospect of playing them in this kind of form, having given Wales a tough clash and drawn with Georgia.

Australia vs Portugal is scheduled for a 4.45pm BST kick-off time on Sunday October 1, 2023.
