Stumps on Day 2. A day of toil for India. The morning started well enough with Bumrah removing both openers quickly and then Nitish Reddy getting rid of Labuschagne soon after. Post lunch though, India were just hunting leather as Travis Head got going once more. He arrived at the crease when Australia were 75/3 and by the time he was finally dismissed for 152, he'd taken Australia to a position of strength at 327/6. He scored freely from the moment he came to the crease and initially, almost helped Smith along at the other end. Once the partnership started to blossom, Smith started to find his groove too and they piled on the runs.

Australia puts 400 runs on the board in the 99th over with Alex Carrey and Mitchell Starc on the crease

Starc would like to contribute with bat as well

Length delivery on off-stump by Siraj, Cummins hangs back and just eases it through point for a couple of runs

Banged in short outside off, Carey was running down the pitch and made a late adjustment, got his bat high and just swatted it over mid-on

Nitish Reddy to Cummins, 1 run, pitched up full and outside off, Cummins throws his hands at it and slices it away to deep backward point

2 runs, length delivery outside off, Carey skips down the track looking to loft it over extra cover but he doesn't get it out of the middle, sweeper cover keeps it down to two

1 run, good length delivery on off-stump, Cummins just blocks it towards mid-off and they get a single

Bumrah strikes again. Caught by Kohli!! Edged and caught! Bumrah continues to produce for India, but he's been the only one doing so. On a good length and holding its line outside off - Marsh is tentatively forward in defence, the ball holds its line and finds the edge, goes at a good height to second slip where Kohli clutches it reverse cupped.

It took time, but Smith has his 33rd Test hundred, raucous celebrations in the crowd, but it's more muted from the batter - removes his helmet, lifts his bat towards all corners of Gabba and then leaps in delight. Has there been a more popularrt hundred in recent times? He certainly looks very relieved - was a full ball that was nudged down to long leg and he immediately called for a single

Head doesn't seem to care about the ball and welcomes Bumrah with a Four on a lenght ball

Head slams a Four to long-off. He leans forward and bludgeons the drive, straight of mid-off and the ball races away

Closing on a century, Smith seems dangerous

Rohit runs across from slip, has a chat with his bowler and then runs back to his position - a wide slip, gully and a third man in place

Fuller length delivery and well wide of off stump by NKR, Smith reaches out and caresses the drive wide of cover, and gets 4 runs

Jadeja drops the ball short and wide of off, Head backs away and cracks it in front of square on the off-side, sends it racing away to the ropes

FOUR, drilled, the runs keep flowing for Head - overpitched by Nitish, Head leans forward, presents the full face of the bat and drives it back past the non-striker for a boundary

Australia's session through and through, they get through unscathed and the runs came at a healthy pace courtesy Travis Head. He's taken a real liking to India over the past year or so and continued to torment them today. He scored at will, rotated the strike nicely when he wasn't crunching them to the boundary and notched up his 9th Test century. He came in when Australia were 75/3 and the game was certainly in the balance but his century has completely turned things in Australia's favour. Meanwhile, Steve Smith has been settling into his groove as well, he looked a lot easier at the crease as the session progressed and started to bring out some of the shots he plays when in top touch. India looked bereft of ideas and deflated. The field followed the ball and they've completely lost control of proceedings. We'll be back after tea.

1 run and strikes comes back to Head. Head at 98

Head hits Bumrah to a Four. Head just drives it on the up and through mid-on and moves to 97 runs

Length delivery outside off delivery by Nitish Reddy, fraction short short and wide, Head absolutely hammered it towards point, was in the air and not far to Kohli's left, he just flinched and looked to take evasive action, might not have spotted it off the bat

Length delivery on off-stump by Jadeja, Head presses back and across before slapping it firmly through cover

With 1 more run, loud cheers as Smith gets to fifty, tossed up full on middle, Smith knocks it towards a deep-ish mid-on and gets across, measured celebration from Smith, just a raise of the bat to acknowledge the applause

FOUR, to backward square leg, the partnership between Head Smith reached to 100+ runs. Banged in short on middle-leg, got about shoulder-high, Head latched on to it very quickly and pulled it right into the gap at backward square leg
