Shikhar Dhawan was 73 not out from 72 balls, and captain Virat Kohli was 3 not out.

India chose to bat first, and Dhawan and Rohit Sharma bided their time before opening up once Australia fast bowlers Mitchell Starc and Pat Cummins were changed.

India's openers Rohit Sharma and Dhawan reached 41-0 after 10 overs, but let loose against the change bowlers and were untroubled in achieving their 16th century partnership, tied for second in one-day internationals history with Adam Gilchrist and Matthew Hayden. Sourav Ganguly and Sachin Tendulkar lead with 21.

The partnership was broken at 127 in the 23rd over when Sharma edged behind a Nathan Coulter-Nile riser.

Sharma, who scored an unbeaten century in India's opening win against South Africa, fell for 57 from 70 balls.

India opener Rohit Sharma became the fourth batsman to score 2,000 runs against Australia in one-day internationals, during their Cricket World Cup match at the Oval.

He joined Sachin Tendulkar (3,077 runs), Desmond Haynes (2,262), and Viv Richards (2,187).

Sharma is also the fastest to 2,000 ODI runs against any side, in 37 innings.

He and Shikhar Dhawan were 41-0 after 10 overs, but opening up to be 81-0 after 16 overs.
