Steve Smith believes Australia were "near flawless" thrashing Sri Lanka by an innings and 242 runs for their biggest Test win on the subcontinent.
Australia took a staggering 15 wickets either side of enforcing the follow-on on day four and wrapped up the series opener in picturesque Galle by tea.
Across the first two days, player-of-the-match Usman Khawaja (232 runs), Smith (141) and debutant Josh Inglis (102) laid the platform for a mammoth 6d-654 that Sri Lanka (165, 247) never looked like reaching.
Veteran Nathan Lyon (3-57, 4-78) and left-arm off-spinner Matthew Kuhnemann (5-63, 4-86) inflicted the bulk of the damage with the ball, the latter barely two weeks after dislocating his thumb playing Big Bash League.
The win overtook a 2002 defeat of Pakistan in the UAE - by an innings and 198 runs - as Australia's biggest in Asia, and is the team's fourth-largest of all time.
"It was almost a near flawless performance," said stand-in captain Smith.
"The way we started was great and we had plenty of partnerships throughout to get to 650.
"Then the spinners bowled beautifully in tandem."
The loss is also Sri Lanka's largest in Test history, eclipsing the defeat by an innings and 239 runs that India inflicted in 2017.
In at No.9, Surprise top-scorer Jeffrey Vandersay (53) appeared to have been aware that Sri Lanka had come up just short of avoiding a new low.
The game was over when Mitch Starc caught Vandersay at backward point from Kuhnemann on the delivery after he made his half-century, and he kicked the dirt in frustration.
The wicket had begun to deteriorate by the time Sri Lanka were batting, but the hosts nevertheless came up with some embarrassing batting on home soil.
"The shot selections were not the best," said Sri Lanka coach Sanath Jayasuriya.
"We have experienced players so they'll have to adjust themselves. We're playing against the No.1 team and the world. We know they're tough."
Most notably, veteran Dimuth Karunaratne (0) completely left Todd Murphy (0-28, 1-57) to career into his off-stump in the second innings.
Fellow opener Oshada Fernando (6) came up with one of the all-time bad lbw reviews by sending a Starc (2-13, 1-4) in-swinger upstairs.
Balltracker showed it was hitting his middle stump, with the pair of brain-snaps leaving Sri Lanka in trouble at 2-6 in the second innings.
Kuhnemann took breakthrough wickets throughout Saturday, opening the floodgates in the first innings when he had Kusal Mendis (21) caught at square leg.
The scalp triggered a collapse of 5-9 that left Sri Lanka all out for 165 in 26 balls, after they'd begun the day at 5-136.
Mild-mannered Kuhnemann ripped through the tail en route to his second five-wicket haul from four Test matches.
"Left-arm spinners, (bowling) in particularly to right-hand batters, it just works in the subcontinent," Smith said.
In the second innings, Kuhnemann enticed strike weapon Kamindu Mendis (32) into hitting into the wind to midwicket and then took captain Dhananjaya de Silva's wicket for the second time in the game.
Just as he looked to have his eye in, De Silva (39) edged Kuhnemann to Beau Webster at cover.
Lyon dispatched the only batter providing resistance in the first innings, Dinesh Chandimal (72), by bowling around the wicket to strike him on the back pad.
In the second innings, he helped Australia cut into the tail, with Alex Carey stumping Sri Lanka's last recognised batter Kusal Mendis (34).
Lyon bowled off-spinner Prabath Jayasuriya (1) attempting a slog sweep on the next delivery but Nishan Peiris (0) hit him to cover before he could snare a first Test cricket hat-trick.
The tail hung around more than in the first innings - with Smith throwing the ball to Travis Head (0-8) for two overs - before Kuhnemann landed the final blow.
