Aaron Finch has revealed the thought of fielding for 50 overs doesn't excite him anymore, and that he isn't regretting his decision to retire from the format.

Still captaining Australia's T20 team, Finch will lead the nation into a T20 World Cup defence which starts in the coming weeks on home soil.

Prior to that, Australia play their final lead in series against the West Indies and England over the next week and a half.

Finch said he had no regrets over retiring from the 50-over format, while also hoping the decision will extend his T20 career.

"It is something that I am in no way regretting," Finch said on Tuesday.

"The thought of fielding for 50 overs doesn't excite me anymore. Twenty overs is certainly exciting. I am comfortable with the decision I have made and hopefully that will allow me to play a little more T20 for longer."

Finch's retirement came at the end of back-to-back series against Zimbabwe and New Zealand, where more poor form with the bat capped a miserable two years for the former captain.

While Australia now scramble to name their replacement with an ODI World Cup just 12 months away in India, Finch said he will continue to be overly aggressive in the T20 format as he attempts to get out of his form rut.

"If in doubt, be overly aggressive. That is how we want to play," he said.

"At times that is going to come with high risk and high reward. At times it comes with no reward. That is just a part of T20 and you respect that, but I feel like I am hitting them really well and my game is in good order."
