Australian Azra Hadzic, 19, took down top seed Magda Linette in a third set tie break 6-4, 6-3, 7-6.

The Bosnian-born Hadzic, ranked 352 in the world, fought hard after losing the second set to claim a memorable victory over the Polish product in her short career.

Australian Open junior champion Elizaveta Kulichkova was impressive in her first round match, defeating second seeded American Irena Falconi in three sets.

The Russian won the first set 6-3 before Falconi fought back to claim the second, however, Kulichkova powered on to easily win the final set 6-1 and advance through to the second round where she will face Italy's Jasmine Paolini.

Paolini won her match against Japan's Hiroko Kuwata in the same fashion.

Third seed Olivia Rogowska ended qualifier Naiktha Bains' run of good form in straight sets 6-2, 6-3.

Rogowska's heavy hitting was too much for Bains who lost five games to 12 to the event's new top seed.

Other round-one singles winners include Japan's Miyabi Inoue, Yurika Sema, Eri Hozumi and Miharu Imanishi, Great Britain's Naomi Broady, America's Julia Cohen, China's Yuxuan Zhang and Ukraine's Anhelina Kalinina.

Australian Priscilla Hon will tackle Hadzic in today's second round first up on centre court for a quarter final spot after she defeated Ellen Perez yesterday.

Rogowska will play Imanishi before the feature match between Paolini and Kulichkova.
