Wales coach Warren Gatland said that mistakes had cost them in their 33-12 defeat to Australia on Saturday.
"That was the most disappointing performance since I've been in charge of Wales," Gatland said
"They thoroughly deserved to win, they were really up for it today the Australians, really hungry and they dominated us in most facets.
"The four tries they scored have all been form our mistakes and our turnovers, that's Test match rugby."
Centre Digby Ioane, lock James Horwill, flanker David Pocock and substitute hooker Tatafu Polota-Nau all touched down for the Wallabies, while fly-half Matt Giteau booted 13 points.
Wales were also not helped by losing their record Test try scorer Shane Williams to injury early on, while his fellow wing Leigh Halfpenny and a third British and Irish Lions cap, hooker Matthew Rees, were also soon forced off.
"We spoke at half-time that we were still in the game [at 23-12 down]... I was questioning, it looked like we had a little bit of a lack of energy and a lack of urgency in that first half," Gatland added.
