Brisbane UFC fighter Bec Rawlings has finally got her wish, and in front of what will be a packed crowd at Qudos Arena in Sydney, she's ready to finally show her true potential in the UFC's newest weight division.

Rawlings spoke to Fairfax Media last year and said the introduction of a 125-pound women's flyweight division had the potential to be a massive success.

"I feel like a lot of girls in the strawweight division are killing themselves to make weight," she said.

"There's a lot of bigger girls who would love to have the 125 division and I'm one of them, but until then we're stuck in the 115 division and busting our arses to make weight.
