A fighting half-century from Shaun Marsh has virtually ensured that Australia will do no worse than draw the third test against India at the MCG, and with it win the Border-Gavaskar trophy.
Marsh ended day four unbeaten on 62, while tail-end hero from the first innings, Ryan Harris, made a gritty, unbeaten eight as Australia finished the day on 261-7, a lead of 326.
The test, which has degenerated at times into an ugly sledge-fest, will almost certainly end in a draw unless India collapse in their second innings or pull off a miracle chase.
Chris Rogers made his fourth straight half century, but again was left frustrated in his elusive pursuit of three figures. Rogers clipped eight boundaries to bring up 69 before he was clean bowled by Ravichandran Ashwin (2-21).
David Warner slogged 40 runs off 42 balls before lunch, but Australia's charge was slowed by the loss of Shane Watson and Steven Smith in the second session, which was delayed more than an hour by rain.
