Justin Langer and Matthew Hayden will lead the run chase
Australia have promised a positive approach on the final day of their series-deciding Test against India at the Sydney Cricket Ground.
They need to score another 433 runs in 90 overs to give skipper Steve Waugh a winning finish to his Test career.
"It's going to be a tough assignment," batsman Simon Katich admitted.
"Funny things can happen in this game. If we get off to a really fast start again, you never know what can happen. It's a quick outfield."
No side has scored more than 276 in the fourth innings to win a Test in Sydney.
And if Australia reach their target, it would beat the record 418 made by West Indies against them in Antigua last year.
"I think the guys still believe (we can win). If you don't have that belief, you don't have a chance," said Katich, who made his maiden Test hundred in Australia's first innings.

"The way we play, we try to be positive. That showed in our first innings, the fact that we could score so quickly despite being so far behind in the game.
"It would be a phenomenal effort but we'll just to have to
see how we go in the first session."
Anil Kumble will be India's main threat, having taken 8-141 in the first innings, the best figures in a Test at the ground since 1898.
It also enabled him to equal Kapil Dev's Indian record of 23 five-wickets or better hauls in a Test match innings.
With 1,400 runs already scored in the game, India were making no bold predictions at the end of the fourth day's play.
They have a chance to win a series in Australia for the first time, but vice-captain Rahul Dravid said the pitch was still a good one for batting.
"Their chances of batting through the day are pretty good, but the first session tomorrow is going to be critical.
"The key to their batting in this series has been their top three batsmen and if we can get them early, then we can put pressure on them," he said.
"We'll need a big effort, we'll need somebody to bowl well. Hopefully the last day wicket might play a few tricks.
"We just believe we've got a lot of hard work ahead."
