Australia currently lead the series 1-0 after three matches and although Tredwell conceded a lot of runs in the first ODI, he feels that there is an opportunity for wickets.
"We're approaching this as a semi-final/final scenario," he told Sky Sports News. "It's a massive game, and we want to go into that last one at 1-1 with a chance to win the series.
"They came pretty hard in that game at Old Trafford. It was a plan by the looks of it, and on another day it could have been 3-20 after four overs. If they come pretty hard it gives me a chance to get a few wickets, hopefully.
"You just try and make it as hard for them as possible - batten down the hatches and challenge them to hit you in places they don't want to."
England must win the fourth ODI if they are to stand a chance of winning the series.
