Mitchell Johnson capped his recall to the test side with a four-wicket haul, including his 200th victim, as Australia skittled Sri Lanka for 156 before tea on day one of the Boxing Day test at the MCG.
Pugnacious opener David Warner then set the tone in the final session, smashing 62 off 46 balls before Australia wobbled slightly, losing three quick wickets including an embarrassing run out of Phil Hughes (10).
Still, at stumps, it was the home side well on top, with skipper Michael Clarke and Shane Watson unbeaten at the crease and the total 150-3.
Left-armer Johnson, who claimed six wickets in his comeback test against South Africa in Perth last month, then was overlooked for last week's first test in Hobart, claimed 4-63 from 14 overs and bowled with tremendous pace.
