India must have been thinking the worst at tea on day one after coming into this series on the back of an historic 3-0 home series defeat by New Zealand.
They rallied brilliantly, though, led by the excellent stand-in skipper Bumrah.
He was superb with the ball but also captained expertly, changing his bowlers effectively and knowing when to attack and when to soak up pressure.
Usual captain Rohit Sharma, who missed this game after the birth of his second child, is expected to return for the second Test. He batted in the nets on Monday.
Shubman Gill may also return at three after a knock to the thumb in the warm-up game, while seamer Mohammed Shami has started his return from a year-long absence and may now play a part in this series.
The tourists, who play a two-day game against a Prime Minister’s XI before Adelaide, will have to decide how to balance their squad and whether Rohit breaks up the opening pair of Yashasvi Jaiswal and KL Rahul, who shared a brilliant double century stand in the second innings in Perth.
All-rounders Ravichandran Ashwin, who has taken 11 wickets in his past two Tests in Adelaide, and Ravindra Jadeja may also come into the reckoning.
India came into the series with questions, but the ones they have now are far more welcome.
