Samantha Stosur has lifted her Brisbane curse in fine fashion, toppling former world No.1 Angelique Kerber to reach the second round of her home event for just the second time in seven years.

The 35-year-old withstood the German's best efforts in a 7-6 (7-5) 7-6 (7-4) win built on smart serving and variety from the baseline, rallying from 5-1 down in the first set tie-break for a win she described as her best in Brisbane.

Stosur, the 2011 US Open champion, has traditionally struggled on the Australian swing but the veteran will move towards the year's first grand slam knowing she's still capable.

"I'm very, very happy with that win ... probably my first top-20 win in a little while," the world No.99 said.

With Australian world No.1 Ashleigh Barty assuming the mantle of top dog, Stosur has been afforded a lower profile than previous years.

But she said the stress-free tennis played on Monday night - Stosur admitted she played like she "forgot she was down 5-1" in the tie break - was what she had always been aiming for.

"It's probably my best win here," she said of the defeat of the world No.20 and three-time grand slam champion.

"It's sort of the way I want to be all the time on the court (but) I put more pressure on myself than anyone would ever do.

"Sometimes I want it a little too bad and that's when you get hamstrung, but today I felt like I stayed relaxed and composed and did those things I want to do all the time."

Stosur, who is on the same side of the draw as world No.1 Ashleigh Barty, will play the winner of the match between American eighth seed Madison Keys and Czech qualifier Marie Bouzkova in the second round.

Fellow Australians Ajla Tomljanovic and Priscilla Hon went toe-to-toe later on Monday, Tomljanovic prevailing 6-2 4-6 6-4.

Earlier Czech Republic's Barbora Strycova upset British seventh seed Johanna Konta 6-2 3-6 6-3 to move into the second round and No.4 seed Elina Svitolina was thumped 6-1 6-1 by American Danielle Collins.

Strycova will face American Alison Riske who defeated Czech Karolina Muchova 6-4 6-2, while Sofia Kenin beat Anastasija Sevastova 7-6 (7-1) 6-4.
