Alicia Molik was made to work hard before triumphing over compatriot Samantha Stosur in the women's final of the Sydney International.
The sixth-seed beat the 59th-ranked Stosur 6-7 (5/7) 6-4 7-5 to claim
her fifth career WTA title.
Molik became the first Australian woman to win the Sydney title since Wendy Turnbull's success in 1980.
It was the first all-Australian women's final at the event since 1978 when Dianne Balestrat downed Turnbull.
The last time there was all-Aussie women's final on the WTA Tour was in 1992 when Nicole Provis defeated Rachel McQuillan.
Molik's win made it an Australian title double after Lleyton Hewitt beat Czech qualifier Ivo Minar in the men's final earlier on Saturday.
Stosur reached the final after two walkovers in her quarter-final and semi-final to world number one Lindsay Davenport and Russian world number six Elena Dementieva.
But she demonstrated in Saturday's final that she could prove a testing first-round opponent for French second seed Amelie Mauresmo at next week's Australian Open in Melbourne.
