Beating a struggling Wallabies outfit, though, and halting New Zealand's relentless Grand Slam march through Great Britain and Ireland is on a poles-apart scale comparable with the relative scrummaging ability of England destroyer Andrew Sheridan and hapless Australian tighthead Al Baxter.
Australia have now lost seven successive Tests, while the All Blacks followed up their 41-3 mauling of Six Nations champions Wales by smashing Ireland 45-7 at Lansdowne Road, despite coach Graham Henry making wholesale changes.
Henry will surely parade his big guns next weekend, including Dan Carter, Tana Umaga, Richie McCaw and Chris Jack, as New Zealand, less than two years from the next World Cup, will want to scatter their calling card all over Twickenham.
All Blacks history is also stacked against England, with just four home wins from 16 attempts in the bag, confirming New Zealand's status as red-hot favourites to successfully complete the third - and undoubtedly toughest - leg of their Grand Slam mission.
England, though, can take heart from the way in which they demolished Australia up front, where Baxter was reduced to rubble by Sheridan and the line-out functioned effectively throughout.
Behind the scrum it was not so impressive, and Australia looked a far more dangerous unit with ball in hand, but England's first game for eight months proved a relatively straightforward experience.
"The win was the key thing, and we got that," said number eight Corry.
"We set out to dominate possession and territory, which we did, and it was very pleasing to come away with a victory.
"I think if we are being brutally honest, though, perhaps the score we registered didn't reflect the amount of territory and possession we had, so there are things to work on.
"It's going to be another step up next weekend. Just look at New Zealand's results - they are a great side.
"Are they beatable? Yes, but as yet we haven't formulated our game plan. We've played Australia and beaten Australia, so that is job done, so let's now focus on New Zealand," he added.
"This game is all about winning, and I thought we strangled Australia and kept hold of the ball. We didn't score as many points as we wanted, and perhaps what our possession and territory deserved, but you have to credit their defence.
"We want to start creating a great team spirit within this squad, and we want to be very ruthless when it comes to playing at Twickenham, and you can only do that by ticking games off as they come."
Substitute Olly Barkley's long-range penalty midway through the second-half set England up for a first victory over Australia since the 2003 World Cup final.
Wing Mark Cueto then completed the job by maintaining his remarkable record of a try per Test since he made his debut last season, while England also claimed a well-worked score from wing Ben Cohen and fly-half Charlie Hodgson kicked 11 points before going off with groin trouble.
Australia had Baxter sin-binned for repeated scrum infringements, and his front-row colleague Matt Dunning was carried off with his neck in a brace, meaning the final stages of an often scrappy encounter produced a disappointing scenario of uncontested scrums.
Sale Sharks powerhouse Sheridan deservedly took man-of-the-match honours for a brutal wrecking job on Baxter, and England head coach Andy Robinson rightly sang his praises following a colossal individual performance that mocked Sir Clive Woodward's decision not to start him during any of the British & Irish Lions Tests in New Zealand earlier this year.
"He had a top game," said Robinson.
"He has been waiting for this occasion. It is an opportunity he has earned from his performances in the last six months, and he really hit the ground running right from the start.
"He has really developed, working under Phil Keith-Roach (England scrummaging coach) and Kingsley Jones at Sale. This is the start, and it is not about one performance for Andy Sheridan, it's how he moves forward.
"He has a different challenge next week, a very tough challenge against the All Blacks, who are the best team in the world.
"But he destroyed what was put in front of him against Australia, and that is all you could ask of a player."
