Some superb fielding helped the Sri Lankan cause, with a couple of fine catches, highlighted by Nuwan Kulasekara's brilliantly athletic caught and bowled to remove the dangerous Michael Hussey for 23.


However, last year's beaten World Cup finalists were not as effective with the bat and looked headed for certain defeat at 180 for nine, still needing 51 to win.


But Angelo Mathews and Dhammika Prasad put on 46 for the last wicket to threaten to snatch an incredible win.


The pair needed 18 to win from the final over and Mathews hit the first two Mitchell Starc deliveries for four and six to narrow the equation to just eight from four balls.


Two singles left them chasing six from the last two balls, but Mathews (64) holed out to Daniel Christian on the long-on boundary from the penultimate ball to hand the relieved Australians a thrilling victory.
