Sharma, along with Aussie wildcards Kimberly Birrell and Zoe Hives, are hoping to roll on when they return on Wednesday for surprise second-round appearances at their home grand slam.

The trio, who are close friends, were still on cloud nine on Tuesday after guaranteeing themselves at least a $105,000 pay day and another opportunity to play in front of friends, family and adoring fans.

"We're incredibly lucky to have a grand slam in our country and the support has been overwhelming," Birrell said.

"It's really a dream come true to play here in Melbourne."

The 20-year-old, who lives on the Gold Coast, said she couldn't wait to get back on the court to play 29th-seeded Donna Vekic and "do everybody proud"

Sharma, who defeated her friend and another fellow Aussie Priscilla Hon on Monday, said she was taking the tournament "one match at a time".

"At the end of the day its another match and I want to keep things pretty low key and the same," she said ahead of her meeting with Greece's world No.45 Maria Sakkari.

"I know it's a really big tournament but again its a game and just want to keep it really consistent."

Victory for the 23-year-old Sharma, who also powered through three qualifying matches to make the main draw for the first time, would set up a showstopper with Barty, if the Australian No.1 also beats China's Yafan Wang on Wednesday.

"It would be a dream come true to play Ash on such a big arena in front of a home crowd," Sharma said.

"Obviously (I have) a lot of respect for Ash and she's been doing so well, just to even get on the same court as her would be such an opportunity."

Ballarat-born Hives isn't looking as far ahead, saying she's happy to have made it to her round-two clash against 19th-seeded Frenchwoman Caroline Garcia.

"Tomorrow the pressure is all off," 22-year-old Hives said.

"It's just a great experience and whatever happens, happens ... (I'm) hoping to learn a lot from it."
