Brisbane: Australia beat Sri Lanka by an innings and 40 runs inside three days in the series opening day-night test in Brisbane on Saturday.
Pat Cummins (6-23) was the pick of the Australian bowlers, claiming his first 10-wicket match haul at the Gabba and setting up Australia's second test victory in over a year.
The teams move to Canberra for the second and final test from Friday.
Resuming at 17-1, Sri Lanka’s hopes of saving the match were dealt a heavy blow when Dinesh Chandimal and Kusal Mendis fell in consecutive overs from Cummins at the start of the day.
After taking a wicket with the final ball of day two, it took Cummins (6-23) just two balls on day three to get his next wicket, squaring-up the scoreless Chandimal and finding the edge which ballooned to Kurtis Patterson at gully.
In his next over, Cummins teased an attempted drive from Kusal Mendis (one), who edged to Joe Burns at second slip giving the Australian seamer the extraordinary early figures of three wickets for no runs.
Thirimanne (32) and Roshen Silva (three) briefly stemmed the flow of wickets, before Cummins got his fourth, having Silva caught by Burns in the slips to reduce the tourists to 35-4.
On Friday, a 166-run stand between Travis Head and Marnus Labuschagne powered Australia to 323 in reply to Sri Lanka’s first innings total of 144.
