Welcome to the coverage of Day 2 of the fourth and final Test between Australia and India in Brisbane on Saturday.

India will be aiming to pick up a few early wickets and keep Australia's total in check after the hosts had taken the upperhand on the opening day.

Marnus Labuschagne hit a century as Australia exploited India's injury woes and punished their poor fielding to reach 274 for five at the close of a steamy day one.

Captain Tim Paine was 38 not out and all-rounder Cameron Green on 28 at stumps, with Australia holding sway after winning the toss and batting on a Gabba pitch that flattened obligingly for the batsmen under a blazing sun.

It was a bad toss to lose for Ajinkya Rahane's decimated side, shorn of pace spearhead Jasprit Bumrah and spinner Ravichandran Ashwin, and stitched together with four injury-forced changes.

Selectors spread the load with a rookie four-prong pace attack, but it was soon a man down when seamer Navdeep Saini went off the field with a groin injury after lunch.

He exited straight after inducing a nick from Labuschagne that was dropped in the gully by Rahane when the batsman was on 37.

Labuschagne was then dropped on 48 before tea and duly made India pay in a 113-run partnership with Matthew Wade (45) before getting out slogging for 108.

India blew a third chance late in the day, with Green reprieved on 19 by paceman Shardur Thakur, who grassed a waist-high caught-and-bowled chance.
