Emma Raducanu says she "fully trusts" the ankle injury that threatened her participation at the Australian Open.
The 20-year-old Briton rolled her left ankle in Auckland nine days ago, but says she is ready to play in Melbourne.
Raducanu, ranked 75th in the world, faces Germany's Tamara Korpatsch in the first round on Monday.
"I've been able to do preparation, albeit more limited than usual. But I'm feeling in a good place to go out there and give it my best shot," she said.
Raducanu, who stunned the world by winning the 2021 US Open as a teenage qualifier, has been hoping to put behind her the injury problems that marred her first full year on the WTA Tour.
