Playmaker George Ford says the Wallabies will come even harder at England in the second Test in Melbourne, but he made it clear the visitors are "desperate" to clinch a maiden series victory in Australia. 
Ford was a surprise omission from Eddie Jones' starting side in the first Test in Brisbane, selected on the bench as second fiddle to Owen Farrell at five-eighth and Luther Burrell at No.12.
The 23-year-old, however, had a positive impact when Jones injected him into the game and hauled Burrell off in the 29th minute - far earlier than Michael Cheika and the Wallabies would have anticipated.
He and Farrell were crucial to England's attack, with their experience playing together, even in a Junior World Cup final in 2011, helping England to an upset victory in Brisbane, a venue they had not tasted success at in 41 years.
Ford said there was no time to get swept up in their history-making win and was adamant complacency would not creep into the England camp, particularly under the Jones regime.
"They'll want to get one back up on us; we're desperate as well," Ford said. "We want to make sure we improve. It was great to start the series with a win, but the attention has quickly turned to this week. We've got a huge challenge. We've got to improve our performance, especially if we are to get a good result."
England will name their team for the second Test on Thursday evening, with mounting speculation Ford may be given back his starting No.10 spot after a stellar performance alongside Farrell, who moved to inside centre when Burrell left the field.
It was a welcome return to form for Ford who copped a barrage of boos from the English crowd after missing six from seven kicks in last month's 27-13 win over Wales at Twickenham.
Wallabies hooker Tatafu Polota-Nau said on Tuesday England may have woken the beast that is Australia's forward pack and Ford agreed, saying it would be foolish to underestimate the hosts.
"They'll probably be disappointed with the first result and they played some really good stuff, especially in the first 20 minutes ... they'll be aiming to do that for the full 80 minutes," Ford said.
"All we're focused on is this game this week against probably a more determined Australian team after that first game. It's a great challenge for us at AAMI Park and we're just focused on this game. We still think there's areas of our game that we can improve on."
Asked whether a series win in Australia would help to heal the wounds of England's World Cup defeat to the Wallabies, Ford said: "We've moved on from the World Cup. We had a good start in the Six Nations; we thought we played some decent stuff in a few of those games.
"[We're] still coming together as a team. It's only our fifth, sixth, seventh game together, so in the grand scheme of things we haven't been together that long, but we've been looking to improve every training session."
