World number one Ashleigh Barty produced "a perfect match" to crush Caroline Garcia 6-0 6-0 and draw Australia level with France in the Fed Cup final.
Kristina Mladenovic had given France a 1-0 lead in Perth when she swept aside Ajla Tomljanovic 6-1 6-1.
But Barty - fresh from her win at last week's WTA Finals - needed just 56 minutes to beat world number 45 Garcia and make it 1-1 after Saturday's opening rubbers.
"I couldn't have asked for a more perfect match," Barty said in her on-court interview, according to wta.com.
"I think that's probably the best tennis match I've ever played in my life, and what a place to do it, this is incredible.
"I'm so happy to be back here in Perth. I started my year here, so it's a hell of a way to finish it off too."
Barty returns to face French number one Mladenovic - ranked 40th in the world - in Sunday's opening rubber before Garcia is scheduled to face world number 51 Tomljanovic.
The fifth and final rubber - if needed - will be a doubles match, with Barty slated to team up with Samantha Stosur.
