Astra Sharma is the first local through to the second round of the Australia Open.
Australia was guaranteed a home hope in the second round as Sharma beat compatriot Priscilla Hon in a dramatic encounter at Melbourne Park.
The 23-year-old grand slam debutante won 7-5 4-6 6-1 on Monday before Hon required medical assistance after the pair battled it out for more than two hours in searing heat.
It was Sharma’s fourth win in less than a week, after successfully qualifying with victories over three higher-ranked Russians, including former Wimbledon finalist and US Open Vera Zvonareva.
It means Sharma more than doubles her career earnings, pocketing at least $85,000, having only earned $72,880 during her pro career so far.
Early in the third set Hon required medical assistance, telling an official she “threw up a little bit”.
The Queenslander’s temperature and blood pressure were checked before a doctor was called.
Sharma’s second-round opponent will be the winner of the match between Greece’s Maria Sakkari and French Open 2017 champion Jelena Ostapenko, the 22nd seed.
Meanwhile, fellow Aussie Zoe Hives parlayed her wildcard entry into the biggest win of her fledgling career.
The 22-year-old Victorian defied her ranking of No.225 in the world to upstage seasoned American Bethanie Mattek-Sands 6-1 6-2.
Hives earned a second-round crack at French 19th seed Carolina Garcia.
