Ash Barty will plot a path to victory over Danielle Collins in the Australian Open final with the coach she describes as "a magician" and "a massive part of my life".

Australian home hero Barty has been a hot favourite for the title since before the first ball was struck in Melbourne, and to date she has justified all the hype and expectation.

Barty has dropped only 21 games across six matches to reach the final. Since 2000, only Serena Williams (16 games at the 2013 US Open and 19 at the 2012 US Open) and Venus Williams (20 games at Wimbledon in 2009) have lost fewer games to reach a grand slam final.

The last player to lose fewer games en route to the final in Australia was Monica Seles in 1993 (20 games), and she went on to beat Steffi Graf in a title match that went to three sets.

This is the level Barty is at now, as an established world number one and reigning Wimbledon champion, and a Collins victory on Saturday would be a major upset.

Yet Barty sees the 28-year-old American as a major threat, and the evidence of Collins' destructive performance against seventh seed Iga Swiatek in Thursday's second semi-final attests to that.

Collins won 6-4 6-1 and hit 27 winners and only 13 unforced errors, securing a place in her first slam final.

"She's an exceptional ball striker," said Barty. "She's someone who stands on the baseline and can hit all spots of the court from any position. I think the challenge is going to be trying to get her off balance.

"We'll do our homework and try to figure out a plan, and come Saturday try and execute. Danielle's done incredibly well here in Australia before. The way she's able to control the baseline and really take the game on, she's one of the most fierce competitors out here.

"She loves to get in your face and loves to take it on. It's going to be a challenge for me to try to neutralise as best as I can, but it's certainly nice to see her out here playing her best stuff."

Working out a strategy for the match, alongside Barty, will be veteran coach Craig Tyzzer. Barty trusts him implicitly to get the plan right.

"'Tyzze' is a magician; he's able to look at a lot of different matches, look at key matches, some recent and some old, and work our plan out in looking at different conditions and things like that," Barty said in a news conference after her thumping 6-1 6-3 semi-final win against Madison Keys.

"He's the man that does all the work. I just get to go out there and have fun with it."

Barty is understating her role there, but she has turned singles into a team game, relying on the likes of Tyzzer and mindset coach Ben Crowe to steer her on the right path.

She is attempting to become the first Australian player to win this title since Chris O'Neil in 1978, so the pressure is on, and it helps that those around her help to relieve the stress.

"Everyone is equally important. We're all equal, we all play our roles," Barty said. "The most amazing thing is we all communicate really well together and get along with each other and know when it's time to back off, relax, and then when it's time to switch on and really have a crack.

"'Tyzze' has been a massive part of my life since 2016. Before that, we'd done some work together, but the work he's done in setting up an amazing group of people around us has propelled my career for both of us. The experiences we've been able to share has been remarkable.

"It starts with my family, my sisters, obviously my professional team who contribute as much time and energy into my career and help me try and live out my dreams. I cannot thank them enough for the time and effort they put in to someone else.

"Being able to enjoy it all together and lighten up when we're not focused on the match is a really important part of that."

Barty's first serve has been a huge weapon, while Collins' return of the second serve has been a significant factor behind her run. So if Barty can land enough first serves on Saturday, that could prove telling. It has helped her to save 13 of 14 break points so far in this tournament.

Giving Collins a regular look at her second serve could be costly. Collins has won more points on the return of second serve (90) than any other woman in the tournament.

Barty ranks ninth on that list but is the leader on winning points when landing a first serve, achieving an 83 per cent success rate.
