Hunter's hard-fought 6-4 3-6 6-3 win over German veteran Laura Siegemund on Wednesday vaulted the late bloomer into the Open's last 32, with her singles ranking set to rocket from 180 to 127 - at least.
Her United Cup mixed doubles partner-in-crime Alex de Minaur was so impressed by the win he urged Hunter - the world's top-ranked women's doubles player - to take singles more seriously this year.
"Even before the Australian Open, that was on my radar, as well, just trying to prioritise a few more singles events," said the 29-year-old Hunter.
"It is hard, because a lot of the 1000s are two-week events.
"I've done a really good job to get myself to No.1 in the world in doubles and I don't want to give that up too easily.
"But I'm definitely not young anymore, I'm not planning on playing forever.
"While my body is feeling good, I do want to give singles a good crack ... so I'm going to have to sacrifice some doubles here and there."
De Minaur said what Hunter had achieved already this summer - playing a key role in Australia's run to the United Cup semis and winning her first two main-draw singles matches at her home slam after a decade of toil - was remarkable.
"It's a pretty amazing achievement what she's accomplished, considering the lack of preparation she was able to have going from United Cup straight into qualifying," he said after also powering into the Open's third round.
"Hopefully this gives her the belief to pursue the singles career a lot more."
Making Wednesday's triumph even more special was that Siegemund is one of the few women to recently get the better of the Australian on the doubles court, with wins at the season-ending WTA Finals in Mexico and the United Cup semis.
The German's singles ranking of 78 is also more than 100 spots better than Hunter's, but that disparity counted for nothing on Wednesday in front of a parochial crowd on John Cain Arena.
The first set was an unusual affair, with the first seven games all involving breaks of serve.
Hunter finally snapped the sequence in the eighth game, only for Siegemund to also hold for the first time.
But the Australian kept her nerve from 0-30 down in the 10th game, reeling off four straight points to take the opener 6-4.
Siegemund fought back to level the match at one-set all, but Hunter drew inspiration from a parochial home crowd to claim the decider.
"Being in the third round is a dream come true," she said after also guaranteeing herself a minimum career pay day of $255,000.
"I've obviously watched so many players do it, Australian players like Ash (Barty) and Dasha (Daria Saville).
"They're really good friends of mine and to be able to do that in front of you guys is amazing and in front of my team and my parents."

Hunter's third-round opponent will be Seigemund's regular doubles partner Barbora Krejcikova from the Czech Republic. The No.9 seed made short work of Germany's Tamara Korpatsch 6-2 6-2.
Were Hunter to find a way past Krejcikova, her singles ranking would drop further to the cusp of the top 100, raising the enticing prospect of direct entry into all of the slams.
The only other Australian still in the women's singles draw is Ajla Tomljanovic, who plays Latvia's 2017 French Open champ Jelena Ostapenko in the second round on Thursday.
