Portugal Colonial - Root's superb first ton in Australia guides England to 325-9

Mitchell Starc became the most successful left-arm fast bowler in history as he claimed 6-71, but the opening sessions of the day-night contest were dominated by Root, who scored a masterful 135 not out.

Number 11 Jofra Archer thrilled the travelling army of fans as he smashed a career-best unbeaten 32 off 26 balls with two sixes to provide some late fireworks.

His unbroken 10th-wicket partnership of 61 with Root was a record for England at the Gabba.

The world's top-ranked batsman, Root had failed to reach triple figures on three previous Ashes tours.

But the man who is second on the all-time run-scoring list behind only Sachin Tendulkar silenced the critics who said he couldn't be considered a true batting great until he had made a century in Australia.

Coming to the crease in the third over at 5-2 with Starc swinging the new pink ball, he embarked on an epic knock, bringing up his century with a leg glance to the fine leg boundary off Scott Boland.

Starc's six wickets moved him to 418 in Tests, surpassing Pakistan great Wasim Akram's 414 as the most prolific left-arm paceman in Test history.

"Wasim's still the pinnacle, I think he's still better than me," said Starc.

Starc again was the destroyer at the top of the order, removing Ben Duckett in his first over and Ollie Pope in his second to reduce a shell-shocked England to 5-2.

But unlike in the first Test defeat in Perth, England showed some grit with a 117-run partnership between Root and Zak Crawley, who made 76.

- Lyon left out -

Both teams wore black armbands in memory of former England batsman Robin Smith, who died unexpectedly this week.

Australia, who won the opening Test inside two days, went into this match without regular skipper Pat Cummins.

He had been rumoured to be making an early return from a back injury, but instead the hosts sprung a major surprise by leaving out off-spinner Nathan Lyon for seamer Michael Neser.

It was the first time in almost 14 years that Australia played a Test at home without a frontline spinner.

Duckett was first to go on the last ball of Starc's first over, nicking a full ball to Marnus Labuschagne at first slip for a golden duck.

Pope then chopped on a wide delivery he could have left alone to leave England wobbling.

Crawley and Root survived an examination from the Australian attack and began to take advantage as the wicket flattened.

Root shared important partnerships with Harry Brook (31), Ben Stokes (19) and Will Jacks (19) as England played more conservatively than they had in the first Test.

Root brought up his half-century off 83 balls, shortly after England had reached 150.

Starc was the only Australian bowler who looked threatening, but Boland did produce the ball of the day -- bowling Jamie Smith for a duck with a beautiful delivery which cut back from outside off stump.

England had slipped from 210-4 to 211-6 before off-spinner Jacks justified his inclusion to bolster the batting with some positive stroke play before an expansive drive to Starc brought his downfall

England were 251-7 which quickly became 264-9 as Gus Atkinson and Brydon Carse came and went to a rampant Starc under the lights.

Just when it looked like England would fold, Archer and Root went on the attack.

Pace bowler Archer hit two towering sixes and Root joined the fun with a reverse scoop off Boland that cleared the ropes at third man.
