India won the toss and opted to bowl in the third and final T20 international against Australia at the Sydney Cricket Ground on Tuesday.
Unchanged India are chasing a 3-0 series sweep in Australia for the second time in five years after losing the preceding one-day international series 2-1.
"We are going to bowl," skipper Virat Kohli said.
"There are shorter boundaries here and we had a good game last time. For the bowling line-up as well we wanted to be more professional and test ourselves."
Aaron Finch has recovered from injury and will return to lead Australia, with Marcus Stoinis out with a side strain in the only team change.
"We would have bowled first as well," Finch said. "It's a used wicket and hopefully we'll bat well tonight.
"We did see a bit of turn in the last game and expect the spinners to play key role in the middle overs."
It will be the first time a cricket stadium will be allowed to host a 100 percent capacity crowd since the new Covid-19 protocols were announced recently by the NSW government.
