West Australian Astra Sharma has shocked top seed and former world No.2 Vera Zvonareva in their Australian Open qualifying round one match-up.
Sharma only turned professional midway through last year after completing five years of college in the US but routed Zvonareva, currently world No.95, 6-3 6-2.
The 23-year-old completed a medical health degree at the prestigious Vanderbilt University in Tennessee before focusing full-time on tennis.
She's now two wins away from her first major appearance, as is unheralded Queenslander Kaylah McPhee and England-born Naiktha Bains.
McPhee, a 20-year-old from Brisbane, defeated Liechtensteiner Kathinka von Deichmann 6-3 6-4 on Wednesday.
Bains joined her as one of six Australian women to win their first-round qualifying matches when she bested countrywoman Maddison Inglis 6-3 5-7 7-5.
Olivia Rogowska also took a step towards a ninth main draw appearance at Melbourne Park by beating Katarina Zavatska 6-1 6-4.
The four women joined Tuesday winners Isabelle Wallace and Lizette Cabrera to make it six from 12 Australian women through.
It was a sorry story on the men's side, with a Wednesday wipeout shattering the dreams of every local in action.
Only Thanasi Kokkinakis, who brushed aside Mohamed Safwat on Tuesday, remains in contention to reach their home major.
John-Patrick Smith missed out in qualifying for the sixth-straight time after losing to 19th seed Matthias Bachinger 7-5 6-3.
Former junior star Luke Saville's hopes of returning to the Australian Open for the first time since 2015 were laid to rest by Mats Moraing, who defeated him 6-4 7-5.
Max Purcell, Akira Santillan and Maverick Banes joined them on the scrap heap later on Wednesday in an unfortunate day for Aussies at Melbourne Park.
