The British number three defeated Australian wild card Kimberly Birrell.
It marks the third time in four years that Dart has successfully negotiated qualifying at Melbourne Park – she reached round two in 2020 before losing to Simona Halep – while she has also made it through twice at the US Open.
Asked about her record, Dart said with a smile: “It shows I need to be not in qualifying any more and try to put myself in a position where I can be directly in, because playing three matches against good players is never easy.”
Both players struggled to hold serve, with Birrell managing it just twice in the match, but Dart battled well, twice coming from a break down in the second set.
“I’m just super happy and pleased to be through,“ 她说. “I always knew it was going to be a really tough match. We’re good friends and we’ve practised a lot together but never actually played a match.
“I think I benefited from playing last week here, I got three matches under these conditions. I guess I’ve got the experience of coming through twice here before so I definitely think that helped me today.”
Dart, who has begun working with Britain’s Dave Collins after being guided predominantly by Eastern European coaches, joins compatriots Emma Raducanu, 希瑟·沃森, Cameron Norrie, Dan Evans and Andy Murray in the main draw.
With Covid rates rising sharply in Melbourne, the 25-year-old has been playing it safe and sticking to takeaways in her hotel room – with fish restaurant Hunky Dory her favourite.
她说: “It’s definitely still quite challenging. My main concern is more I don’t want to test positive to then be stuck here and then not be able to get home. I’m just being as careful as possible.”
