A resurgent Steve Smith crunched his second century in as many Tests as Australia built a daunting total on day two of the fourth Test against India in Melbourne on Friday.
The hosts resumed on 311-6 after a dominant opening day where all their top four blasted 50 or more to lay a solid platform, spearheaded by carefree debutant Sam Konstas.
That thrilling action in front of 87,000 fans was equally notable for Virat Kohli's shoulder barge on Konstas, with the Indian superstar fined 20 percent of his match fee.
There was no let up from Australia on Friday, stretching their innings to 454-7 by lunch, with the composed Smith not out 139 accompanied by Mitchell Starc on 15.
Just one wicket fell in the session -- skipper Pat Cummins for a fine 49.
Smith padded up again on 68, with Cummins alongside him on eight.
The veteran batsman showed his intent early with a four from Jasprit Bumrah, while Cummins also batted with freedom, not afraid to play his shots.
They took 15 off one Akash Deep over to bring up their 50-run partnership before Smith hooked Bumrah for six to rub salt in the wounds.
India's body language showed their frustration as the Test slipped away on a benign pitch offering them little.
Smith reached his 34th Test century with a boundary off Nitish Kumar Reddy, which came on the back of a return to form at the last Test in Brisbane where he made 101.
It was a patient innings from the 35-year-old and moved him alongside four other players on the all-list of century-makers, including Sunil Gavaskar and Brian Lara.
Only six players have scored more, led by Sachin Tendulkar's 51.
With the landmark out of the way both players began swinging the bat, with Cummins paying the price, caught by Reddy in the deep off Ravindra Jadeja to end a 112-run stand.
