The visitors then raced to 60 without loss at stumps on Thursday.
Shane Watson (36 not out) and Phil Hughes (23 not out) were batting virtually unthreatened when bad light stopped play.
Earlier Harris claimed three wickets and seamers Trent Copeland, Mitchell Johnson and spinner Nathen Lyon picked up two each to dismiss Sri Lanka cheaply.
Angelo Mathews top scored for the hosts with 58 but only three other players made double figures.
Sri Lanka won the toss and elected to bat first but soon fell into trouble on a pitch that offered early help for seam bowling.
Harris removed opener Tharanga Paranavitana (0) caught behind in the third over. The left-hander played at a delivery moving away from him and the ball took a slight edge through to wicketkeeper Brad Haddin.
Tillakaratne Dilshan (4) left a delivery from Copeland alone but the ball nipped back sharply to hit off stump. Copeland then had Mahela Jayawardene (4) caught by Hussey diving at gully to leave the hosts at 14-3.
Sangakkara and Thilan Samaraweera shared 43 runs to raise hopes of a revival by the hosts, but Harris returned to have Samaraweera (17) caught by Haddin, and Prasanna Jayawardene (18) joined the procession back to the pavilion, caught by Harris off the bowling of spinner Nathan Lyon.
Sangakkara was dismissed by part-time seamer Mike Hussey for 48 including seven boundaries.
Mathews brought up his fourth Test fifty lofting Harris over long-on for a six. Later he was out caught by wicketkeeper Brad Haddin off Johnson. He faced 111 balls hitting three sixes and six boundaries.
Sri Lanka must win the match to have a chance of claiming the three-Test series. Australia won the first Test by 125 runs.
Shaun Marsh received his first Test cap for Australia from his father, former Test opener Geoff Marsh. He replaced Ricky Ponting who returned home for the birth of his second child after playing the first Test.
Sri Lanka spinner Rangana Herath was left out after he suffered a finger injury and leg spinner Seekkuge Prasanna was included for his debut, as the second spinner alongside Randiv.
Australia lead the three-Test series 1-0.
