Catch the score and updates from Day 1 of the India vs Australia 4th Test being played at the Melbourne Cricket Ground.

Jasprit Bumrah has struck with his first ball of a new spell. A loosener from the pacer as Usman Khawaja toe-ends the ball to KL Rahul at short mid-wicket to be dismissed for 57. Australia are 154 for 2 wickets as Steve Smith joins Marnus Labuschagne.

Australia's young debutant Sam Konstas has gotten under the skin of the Indian players with some audacious shots in the first 15 overs. Both Jasprit Bumrah and Mohammed Siraj have been thrown off their lines.

Ravindra Jadeja brought some relief in the Indian camp and brought an end to the explosive show by debutant Sam Konstas. The 19-year-old counterattacked the Indian attack and pushed the tourists on backfoot after Australia won the toss and opted to bat in the fourth Test.
