England's day began with captain Eoin Morgan failing a fitness test, the result of a groin injury sustained on the eve of the match. Dropped down the order, Finch came in and hit 20 from just five balls, all of which came from boundaries.
A number of teams have opted to go with two wrist-spinners, see India's Yuzvendra Chahal and Kuldeep Yadav, in T20Is but Australia appear to lagging behind in that regard.
The win ensured Australia's flawless record against England in T20s at the Melbourne Cricket Ground (MCG).
Ashton Agar - 4/10 - The all-rounder has previously been a thorn in England's side, but could not make much of an impact with the ball, despite bowling fairly economically.
Kane Richardson - 8/10 - Australia's fast bowler led the charge in Melbourne, taking 3-33.
On a hard track to score on, England's stand-in skipper Jos Buttler was the lone ranger with the bat with a 49-ball 46.
Buttler top-scored for them as England could eventually muster 137 runs in their allotted 20 overs.
Once again, Roy and Hales started the innings for England.
Dawid Malan - 3/10 - Malan started okay with 10 from 10 balls, but can count himself slightly unlucky to be dismissed after Warner ran him out with an exceptional bit of fielding.
David Willey got rid of David Warner to jolt Australia early in their run-chase.
Buttler, stand-in skipper for the day, shared a stand of 43 with the lively Sam Billings (29) and remained in place until the final ball of the innings but never looked close to his fluent best. Jordan finished with figures of 2-26, with the two key wickets of Lynn and Maxwell. The blitz took Australia past the finishing line with seven wickets and 33 balls to spare. His run out of Malan who made just 10 runs was certainly far more impressive.
Adil Rashid - 2/10 - Rashid came away wicketless from the game after Australian batsmen put England to the sword.
It was Australia's third consecutive win in the tri-series, which now shifts to New Zealand and a match Tuesday in Wellington between England and New Zealand.
