Chris Jordan takes 3 for 17 and Jos Buttler powers an unbeaten 71 to secure an emphatic eight-wicket win
Dubai: Australia 125, England 126-2 - England won by eight wickets
England flexed their men's T20 World Cup credentials with an emphatic dismantling of Australia in Dubai.
Eoin Morgan's side first restricted their Ashes rivals to 125 before polishing off the target inside 12 overs with eight wickets remaining.
It is Australia's biggest defeats in terms of balls (50) in T20Is and their heaviest by wickets in a World Cup.
Victory puts England top of Group 1 in the Super 12s and on course for the semi-finals while Australia have dropped to third behind South Africa after seeing their net run-rate take a battering.
This defeat as much about England's excellence as the Aussie's ineptitude.
Chris Woakes collected two wickets in the powerplay and pulled off a stunning catch to dismiss Steve Smith (1) to give Chris Jordan the first of his three scalps.
Australia were 21 for 3 by the time the fielding restrictions were lifted, the lowest score by any nation during the second round.
Captain Aaron Finch (44) and Pat Cummins (12) attempted to give them something respectable to defend, but both were removed by Jordan who finished with 3 for 17.
There was never any feeling that 125 was going to prove anything but a walk in the park for Morgan's men.
Jason Roy (22) and Jos Buttler (71*) put on an opening stand of 66 before Adam Zampa finally got the breakthrough.
But Buttler was merciless, hitting five sixes - four of which landed in the top tier of the Dubai International Cricket Stadium - as he put on the joint-fastest half-century of the tournament.
Jonny Bairstow (16*) arrived to put the cherry on top of a routine chase, completed inside a dozen overs which leaves England with a 100 per cent record and Australia with much to improve on in pursuit of a top-two place.
