The Wallabies' worst ever defeat to Scotland has seen them slide in the world rankings, as Ireland leapfrogged the Australians into third.
Ireland took care of business at the weekend with a 28-19 win over Argentina and that kept their rankings point firm at 86.39.
But the Wallabies' 53-24 loss ripped 1.8 points from their total and that was enough to see them slide back down to fourth.
New Zealand's entertaining 33-18 win over Wales preserved their 3.12 point advantage ahead of England atop the rankings, who were unable to accrue any points due to the difference between their ranking and Samoa's.
Scotland's record win closed the gap between their sixth place slot and the Springboks, in fifth, the South Africans rewarded for their 35-6 win over Italy.
Wales held firm in seventh but France's ranking continues to plummet, their draw against Japan causing them to drop below Argentina into ninth, despite the Los Pumas' falling short against Ireland.
Japan cost themselves a famous win against the French by missing a simple conversion and that has kept them in 11th, one spot behind Fiji, who round out the top 10 after a 57-17 win against Canada.
