Their predictability contributed to their downfall, with Henry noting their reliance on using short-ball runners or telegraphing their intentions when spreading it wide, made it all too easy for the Wallabies' defence.
Australia's up-tempo style saw them play more on the advantage line, and with forward momentum they were able to recycle possession without any real pressure from England, which Henry added "was a major reason why they won."
He went on to question why England coach Stuart Lancaster allowed Morgan to talk up their prospects, and was shocked at Danny Cipriani's comments that not one of the Wallabies would make the England team.
"Why did the England management allow their players to talk such drivel to the media, stoking Australia's fire?" asked Henry.
"I couldn't believe Danny Cipriani saying not one of the Wallabies would make the England team and wondered if he had been misquoted.
"One of the golden rules in sport at this level is you never give the opposition a team talk. It's also one of the reasons teams love to beat England - they talk a good game!"
Henry noted that Australia's impressive display has put rival teams on notice, while England are left to dissect where there campaign faltered and conduct their post-mortem.
Ahead of the quarter-finals, Henry lists Australia as the team to watch, but notes South Africa are "distinctly beatable". The Springboks, he added, seem to be relying on "more brawn than skill", and he described Samoa as "one of the big disappointments of the tournament."
simply not good enough
