The 22-year-old will take on American Victoria Leonardo (7-2-0) in the flyweight division for a shot at the big time, with White handing out contracts at his discretion through the series.

Australian light heavyweight Jimmy Crute broke into the lucrative UFC in 2018 the same way.

With a 3-0-1 record, Hackett, from the Gold Coast, said she needed to impress White in Tuesday's fight (early Wednesday AEDT).

"It literally comes down to who he wants to give a contract to," she told AAP.

"Just winning isn't going to do it for him and that's what I've noticed that watching the last Contenders - you have to make a statement.

"He wants a finish or he wants you to absolutely dominate so there's no question about him giving you a contract.

"But I'm fully ready for it and I want to put on a show."

Hackett started in taekwondo as an eight-year-old and then switched over to Muay Thai fighting, winning a world title.

Turning to MMA, she had her first fight in May last year and was already eyeing the UFC before COVID-19 hit.

Originally scheduled for July, the fight has been pushed back twice, while her opponent also changed.

Training solidly under her father Geoff for almost eight months, Hackett said she couldn't be more ready.

'Last year I was on such a roll with fights - I made my MMA debut at the start of last year and then the fights were rolling through," she said.

"In March I had my fourth fight and going into that I knew about Contender and we were ready to back up straight away and then COVID hit 10 days after my fight.

"But I've actually come out of it in the best shape and my camp has been the best one yet."

Hackett said drawcards like Rhonda Rousey, Holly Holm and Amanda Nunes had laid the platform for women to make a career in the sport.

"With females it's just getting bigger and bigger with those fighters setting the standard for the rest of us," she said.
