Sri Lanka is staring down the barrel at 44-3 after Australia achieved its largest ever total in Asia — 654-6 declared — on day two of the first test in Galle.

Australia's Usman Khawaja struck a maiden double hundred and Josh Inglis got a century on his test debut against Sri Lanka to power the tourists to a mammoth 654 for six before they declared their first innings on day two of the opening test on Thursday.

Usman Khawaja's double hundred and twin centuries from Steve Smith and Josh Inglis helped Australia take complete control over Australia on Day 2 of the Test match.
