There was plenty going Australia's way on Thursday, in Brisbane, but it is Jhye Richardson's fine debut that will please them the most.
Australia ended the day at 72 for 2, trailing Sri Lanka by just 72. That was largely down to Richardson, who returned a fine 3 for 26 in 14 overs – he was by far the most economical bowler at 1.85.
With Pat Cummins returning 4 for 39, Australia bundled out the visitors for just 144 after they opted to bat in the pink-ball Test. Then, the young Marcus Harris impressed in the final session, ending the day unbeaten on 40.
Australia lost opener Joe Burns on 15 and Usman Khawaja 11.
