The Wallabies have hammered a woeful Wales team 52-20 in a lopsided thrashing in Cardiff, despite being down a man after Samu Kerevi was sent off for a high tackle.
Hat-tricks for Matt Faessler and Tom Wright condemned Wales to a record 11th straight defeat, with the Cardiff crowd booing their inexperienced team off the field.
It is the Wallabies highest ever score against Wales in Cardiff.
Leading 19-0 after 23 minutes, Wales fought back to trail just 19-13 at half-time thanks to an Aaron Wainwright score and two penalties from Gareth Ainscombe.
But from the second half onwards, the Welsh were truly awful — and a composed, mature Wallabies side that are beginning to show all the hallmarks of a Joe Schmidt-coached team, with patient build up play and flowing backline moves, made them pay dearly.
Despite losing Kerevi, the Wallabies still scored 21 unanswered points while down a man for the 20-minute red card period as Wales completely capitulated in front of their home support.
[SUMMARY]The Wallabies have now won two consecutive victories on their grand slam tour, but this was a very different performance to that at Twickenham last week.
Wales coach Warren Gatland was under pressure to salvage his job but nobody watching would have seen anything that suggested Wales are about to break their slump.
After all, just 13 months ago the Wallabies were humbled by the Welsh in Lyon, losing 40-6 in an embarrassing display that stamped out any vestiges of support for Eddie Jones' second coming.
Now, the tables have well and truly turned, with Wales embarrassed and their coach questioning his future.
This is now officially the worst Welsh team in history — and the Wallabies made them look it, too.
The Wallabies were in control right from the off, managing the expectations of coming into a match as favourites perfectly.
Tom Wright was on the end of a patient move to score 13 minutes into the contest, before Nick Frost's incredible 50-metre score added to Welsh issues.
Matt Faessler then scored off the back of a rolling maul as a silent Principality stadium looked on aghast at what they were seeing.
Wales had their best moments soon after, and must have expected to push on when Kerevi received his marching orders soon after half time.
But it was the Wallabies who ended up scoring twice through rolling mauls — Faessler completing his hat-trick — before a Wright intercept added further insult,
Len Ikitau scored soon after the Wallabies were restored to 15 men having been reunited with his new centre partner Joseph-Aukuso Suaalii, who made a late cameo.
Ikitau, who turned poor Cameron Winnett inside out with a variety of delightful steps, looked to have completed the scoring.
But there was still time for Wright to complete his hat-trick after some neat work from Tate McDermott.
As Wright strolled to the line, the Wales fans, who had already started to head for the exits, booed their side, facing the prospect of a period that promises significant pain, with no end in sight.
The Wallabies, now two-for-two on tour, head to Murrayfield to take on Scotland, but coach Joe Schmidt acknowledged that match will provide a much sterner test of his side's credentials.
