Australian Open: Barty claims maiden Melbourne triumph after thrilling second-set fightback

Barty was made to work hard for her success by unlikely finalist Collins and had to come from 5-1 down in the second set to prevail 6-3 7-6 (7-2) on Rod Laver Arena.

It was to the delight of a partisan Melbourne crowd, who saw an Australian triumph in a singles event at the season's first major for the first time since Chris O'Neil in 1978.

Barty, who has now won 11 matches in a row in 2022, clinched her third grand slam title at the first opportunity, a sublime cross-court forehand sealing a sensational triumph.

Barty had offered the first sign of nerves and had to save the match's first break point with a brilliant forehand winner before recovering to hold.

Yet she turned the tables in the next game, Collins tensing up and conceding the first break when she sent two serves long.

With the crowd behind her, Barty got into her groove, holding with ease before two fantastic forehands paved the way for her to serve out the set.

Barty seemed primed to take the match away from Collins in the second set, yet the top seed was stunned as she slumped to a 3-0 deficit.

Having conceded serve for just the second time in the tournament, Barty squandered two immediate chances to break back, Collins coming out on top in a thrilling rally.

There were more fist pumps from Collins as she held to go 4-1 up. A brilliant passing shot gave Barty hope in the next game, but she rushed a volley and followed with a double fault to hand her opponent two break points.

Collins took the first to put herself on the brink of restoring parity, only for Barty to rally back with a break of her own and start a quite sensational comeback.

Having held for 6-3, Barty appeared to have left herself too much to do when she went 30-0 down on Collins' next serve but reeled off four straight points to send the crowd into raptures before levelling the set with a fine hold.

Collins needed to regain her composure and did so to reach the tie-break, but a foreland long put Barty in control, and the crowd were on their feet after a volleyed winner made it 4-0.

Collins struck the net and then missed the court to grand Barty four championship points, and the comeback was complete with her slick forehand.

The first Australian woman since 1980 to reach the final of this major, Barty became the first woman to win a grand slam title in her home country since Sloane Stephens triumphed at the 2017 US Open.

She is also the first woman ranked world number one to lift the trophy since Serena Williams in 2015, ending a run of top-ranked players losing the Australian Open final, after Simona Halep in 2018 and Serena Williams in 2016.
