Steve Smith continued his revival with a brilliant century as he and the Australian bowlers put the hosts firmly ahead against India after the second day of the fourth Test in Melbourne.
After ending a run of 26 Test innings without a ton in the third Test in Brisbane, Smith followed up with a galloping 140 to help Australia post 474 in their first innings.
It was the 34-year-old's 34th Test century and it lifts him to seventh on the all-time list, in a strong five that includes Brian Lara and Sunil Gavaskar.
Smith's knock included a crucial 112-run partnership for the seventh wicket with captain Pat Cummins, who reached 49.
Smith was eventually dismissed in bizarre fashion when Akash charged Deb and the ball hit the pads from the inside edge before rolling into his leg stump.
India skipper Rohit Sharma's poor form with the bat continued when he fell for just three off Cummins' bowling at the start of India's reply.
The Australian skipper then bowled KL Rahul beautifully just before tea to leave India reeling at 51-2.
Yashasvi Jaiswal and Virat Kohli stabilized the innings with a partnership of 102 before a desperate mix-up saw Jaiswal run out for 82.
Scott Boland then removed Kohli for 36 and Deep for a duck as India slumped to 164-5 at the close, still trailing by 310 runs. Before Jaiswal's dismissal, they were comfortably on 153-2.
The five-match series is level at 1-1, with both sides looking to win it 3-1 to secure a place in the World Test Championship final.
