OITA, Japan (Reuters) - Twice champions Australia overcame a sloppy start to crush Uruguay 45-10 on Saturday, forging towards the World Cup quarter-finals with some exhilarating running rugby despite their problems with high tackles resurfacing at Oita Stadium.
Wrecking ball centre Tevita Kuridrani and Dane Haylett-Petty each crossed twice each, with teenage winger Jordan Petaia sparkling with a try on debut under the domed roof.
Scrumhalf Will Genia and prop James Slipper also grabbed five-pointers for the Wallabies, who shrugged off the heartbreak of their Wales defeat with flair and determination.
Australia had trouble getting low enough in their tackling, with both lock Adam Coleman and loose forward Lukhan Salakaia-Loto yellow-carded in an eventful opening half.
But the Wallabies, wearing their indigenous strip for the first time at a World Cup, were able to mitigate the damage to lead 19-3 at the break before throwing down the hammer in a dominant second half.
The result put Australia top of Pool D ahead of second-placed Wales, putting pressure on the Welsh to beat Fiji at the same venue on Wednesday.
Australia coach Michael Cheika was disappointed with his team's third slow start for the tournament.
"That's three games now, a little bit off the pace at the start. I'll have to work on my pre-match speeches.
"(Uruguay) are big-hearted and they take it to you and they've obviously improved since the last World Cup."
It was a tough day for Uruguay, desperate to impress the powers of global rugby, but they were rewarded with a late try to Manuel Diana in the final minutes.
"I think in the first half we did a really good job but Australia are a really big and fast team. We have to get better for our next match against Wales," said Andres Vilaseca, who stood in for benched regular skipper Juan Gaminara.
The South Americans will take heart from not conceding as many points as they did in the 2015 tournament, when they lost 65-3 to the Wallabies.
Australia had 12 changes to the starting side that lost 29-25 to Wales, with James O'Connor a late withdrawal for a cork injury.
They came out firing but it was a stroke of fortune that created the first try, with a ricochet off the boot of Kurtley Beale taking the ball to the try-line.
With the defence scrambling, Australia whipped the ball cross-field where unmarked winger Haylett-Petty jogged over at the right corner for an easy score in the sixth minute.
Uruguay battled back, with Felipe Berchesi slotting a penalty when Wallabies captain Michael Hooper put a high tackle on Nicolas Freitas as the winger darted toward the line.
A minute later, Australia were down a man, when Coleman was given a yellow card for also going high on fullback Rodrigo Silva.
The action bypassed Petaia in the opening quarter, but he made an impact with his first touch, rumbling the ball toward the line, then linking up with Beale a moment later to sidestep two defenders and pirouette over the line for a 24th minute try.
Beale escaped a yellow for a high tackle but Salakaia-Loto was not so lucky, being sent off for what seemed a less egregious offence a few minutes after Coleman had returned to the field.
Again, Australia brushed off the setback, with the powerfully built Petaia bursting through on the left wing and offloading to Kuridrani for a try on the half-hour mark.
Uruguay would not lie down, though, and a huge roar echoed under the domed roof when centre Tomas Inciarte charged down the right wing for a turnover try a minute before halftime.
It was to a fleeting moment of triumph for the South Americans, however, with the try cancelled by a video review which showed Diana was off-side when he plucked the ball from the ruck.
Australia came out with renewed intent and needed only six minutes to claim the bonus point, with Kuridrani waltzing through a huge hole at midfield to cross near the right corner.
The game then descended into a training run for the Wallabies as green and gold jerseys began punching holes through the Uruguayan line at will.
