Katie Boulter says she can win "a lot of matches" at Grand Slam level as she prepares to launch the British bid when the Australian Open starts on Monday.
The 24-year-old is the only Briton playing on day one of the delayed Grand Slam, taking on Russia's Daria Kasatkina at about 03:00 GMT.
The nation's five other singles stars play their opening matches on Tuesday.
"It's the stage I want to be on," said Boulter, who is playing at her first Slam since last year's Australian Open.
Boulter is ranked 371st in the world and is using a protected injury ranking to play at Melbourne Park.
