The Wallabies have saved their best performance under coach Joe Schmidt for last, thumping Italy 57-10 in Perth.
It's the team's largest win since the 2015 Rugby World Cup (65-3 v Uruguay) and their biggest over Italy in over two decades.

Wallabies lock Josh Canham became the first second-rower to ever score a hat-trick in the gold jersey as the Australians ended their form slump with a bang.
It was a complete performance as they backed up a dominant start to score their most points in a match since 2017, a 63-30 win over Japan.
The win was built off one of the most dominant first halves in the history of the Wallabies.
Six tries rained in during the onslaught, with second-rower Canham starting his haul early.
Canham stretched out for the opener, with Tom Wright and Brandon Paenga-Amosa following him over for a 19-0 lead after 11 minutes.
Italian skipper Michele Lamaro stemmed the bleeding for the moment but it was only temporary.
The Wallabies were on fire as winger Harry Potter was giving the Italians headaches, keeping the hosts on the attack.
Canham crossed for his second, with Angus Bell getting in on the fun after another rolling maul.
Len Ikitau completed the remarkable half as the Aussies went into the break with a 38-5 lead.
Italy provided some nervous moments in the second half when Aussie-born winger Monty Ioane crossed to start the second half.
But Canham completed the hat-trick shortly afterwards, becoming the first Wallabies lock to achieve the honour.
Billy Pollard shortly brought up the half-century but the action was far from over, with Italian prop Marco Riccioni sensationally sent off in the 65th minute, ten minutes after he had been taken from the field.
The incident happened after a scuffle with Miles Amatosero, with the tight-head prop removed from the sidelines for his action.
Italy weren't forced to drop a player but it didn't stop the onslaught of points as Ben Donaldson capped off the victory on the siren with a swan dive.
It made it Australia's largest win over Italy in 21 years, surpassing the 48-point win in 2005 in Melbourne.
