Stand-in captain Steven Smith scored his 10,000th Test run before completing the momentous occasion with a majestic century, while Usman Khawaja reached his 16th ton as Australia were rewarded for an aggressive approach against a spin-heavy Sri Lanka attack on a slow Galle surface.

Khawaja and Smith have combined for an unbroken third-wicket 195-run partnership to capitalise on the batting-friendly conditions in the perfect start for an Australian side striving for a first series victory in
