David Warner slammed his maiden century in T20I cricket to power Australia to a huge victory in the opening game of the three-match series in Adelaide on Sunday.
Returning to international cricket following an abysmal Ashes campaign where he averaged just 9.5, Warner smashed an unbeaten 100, guiding Australia to an imposing total of 233 for two in 20 overs.
The tourists were shellshocked right from the start by Australia's blistering charge with the bat as openers Aaron Finch and Warner were at their belligerent best.
Sri Lanka, captained by veteran paceman Lasith Malinga, were taken aback by the pristine striking unleashed by the duo upfront.
The two batsmen raced to 55 without loss in the Powerplay before skipper Finch cut loose with a couple of maximums off Wanindu Hasaranga's bowling.
Finch's dismissal for an authoritative 64 from 36 deliveries prompted the promotion of Glenn Maxwell, who did not take time to continue Australia's dominance.
The flamboyant batsman brought forth an array of unorthodox strokes including a reverse flick off Nuwan Pradeep and a helicopter-shot towards the end of the innings.
Maxwell's blazing cameo saw him bludgeon 62 runs in 28 balls before perishing in the final over after putting on 117 for the second wicket with Warner.
Meanwhile, Warner tore apart Sri Lanka's bowling with his lusty blows, taking a liking to Kasun Rajitha in particular.
Rajitha bore the brunt of his clean hitting, leaking 75 runs in 4 overs - a record for the most expensive bowling figures in a T20I.
Reacting to the fantastic ton on his 33rd birthday, Warner admitted it was a pleasant change to play in batting-friendly conditions.
"It's great to come out and play on nice true wickets," man-of-the-match Warner said.
"The tone was set by Finchy. I tried to go on and be there at the end. I'd like to think we have enough runs."
In reply, Sri Lanka never looked like challenging the hosts as they lost three wickets inside the Powerplay.
Failing to launch any semblance of a counterattack, Sri Lanka's young team faltered under the feisty pace battery comprising Pat Cummins and Mitchell Starc.
Following a sedate repair job from Oshada Fernando and Kusal Perera, leg-spinner Adam Zampa scythed through the middle order as the visitors fell far behind the asking rate.
Sri Lanka stuttered along to make just 99-9 in their 20 overs, falling to a debilitating 134-run loss - Australia's largest margin of victory in the format in terms of runs.
The two sides will renew their T20 rivalry three days later in Brisbane as Malinga's men try to search for solutions to their batting and bowling woes.
