Australian bowlers took the advantage from India on Day 3's afternoon session as they bowled out the tourists for a paltry 36.
India didn't start well on their overnight score of 9/1 as the night watchman Jasprit Bumrah was dismissed in the second over of the day.
Bumrah drove a short of length straight to Pat Cummins and the speedster didn't make any mistake as he grabbed on to a simple chance. However, what followed was an outstanding fast bowling display and Indian batsmen just knicking everything into the hands of Australian fielders.
First casualty was India's solid No 3 Cheteshwar Pujara. Pujara was dismissed for duck by Cummins' relentlessness of pitching into the off-middle channel on a full-to-good length. The ball shaped away just a touch, which was enough to induce an edge into the hands of keeper Tim Paine.
Now, it was time for Josh Hazlewood to feast on the same lines and lengths and let the ball do its trick. Almost, a replica of Pujara's dismissal took place with Mayank as he too edged the similar length delivery into the hands of Paine.
In the same over, Hazlewood got his second as he drew Ajinkya Rahane to make the same mistake on a little full delivery and India was now on 15/5.
If anybody thought the horror was over, the worse was yet to come.
In the very next over, after hitting a boundary skipper Virat Kohli too fell chasing a wider delivery. He played it towards gully area, where the debutant Cameron Green took the catch in the end, after juggling.
Hanuma Vihari and Wriddhiman Saha put the lid on the wickets' tap for a while, 5 overs to be exact and Hazlewood's beast mode was on yet again.
He first dismissed Saha, who played a full delivery into the hands of the mid-wicket fielder and on the next ball a faint tickle on the ball in the same channel by Ashwin got India reduced to 26/8 and gave Hazlewood his fourth.
Vihari kept the Hazlewood-Cummins duo at bay for some time before he too fell in the same trap and nicked it to the keeper to give Paine his fifth catch and Hazlewood his fifth wicket.
Umesh Yadav hit a boundary but India's innings ended at 36/9 as Mohammed Shami had to retire hurt after he took a blow on his hand and was in serious pain. None of the Indian batsmen could reach double figures as a telephone number starting with 4 could be read as the scores of the batsmen.
This is India's lowest score in a Test match innings, 6 less than their previous lowest of 42, 46 years ago in 1974.
This is also the 5th joint-lowest Test innings total in the history of the longest format of the game.
Australia now needs just 90 runs to win the first match and gain a lead in the four-match series.
