The 22nd seed only 69 minutes to send Bondarenko packing in the third round encounter.
"I feel I play good for today, because before the match I do much homework to study my opponent. I know how to play this match," said Zheng, who never reached second round or beyond in previous Australian Open.Earlier, China's Peng Shuai was dumped out of the event, losing to Serena Williams 6-1, 6-4.
"It's a little surprised that I can win the match so easily, because I know she plays aggressive tennis. So at the beginning I go to the court and play more aggressive than her."
"I think it's really good experience for me. It's my first time to play her," said Peng.Serena will face rising teen star Victoria Azarenka, who ended Amelie Mauresmo's AO campaign 6-4, 6-2.
"The first set, I was a bit nervous, and then a little bit too tight. But after the start of the second set, I feel much better."
"I was up and I get little bit chances, but didn't take that. I learn from her and just keep going."
"It was definitely a lot better than my second round. But, you know, I'm still trying to work on some things and hoping they'll come together," Serena said.She added that her sister's shock upset in the second round had given her extra motivation to win here.
"I'm feeling a little rusty, for whatever reason. I'm hoping my next round I'll be a little better."
"It obviously increases my motivation and my desire to win and hopefully do better."Elena Dementieva, whom I predicted going to have a great run in AO together with Serena, defeated Aussie Samantha Stosur 7-6, 6-4.
The fourth round of AO will continue today.
