Spearheaded by world No.10 Alex de Minaur, Australia will have 20 players in the singles main draws at Flushing Meadows, the same number as 1979 when the great Evonne Goolagong Cawley led the charge.
De Minaur and fellow seed Alexei Popyrin are among 10 men in the top 100 who gained direct entry alongside women's veterans Daria Saville and 2022 quarter-finalist Ajla Tomljanovic.
Wildcards Tristan Skoolkate and Taylah Preston boosted the guaranteed starters to 14 before Li Tu, teenager Maya Joint, veteran Arina Rodionova, Kim Birrell, Priscilla Hon and Destanee Aiava all won final-round qualifying matches on Friday.
The mighty effort marks the first time in US Open history five Australian women have earned main-draw berths through qualifying and the first time in 11 years Australia has had qualifiers in both the men's and women's singles at Flushing Meadows.
The super impressive Joint secured a grand slam main-draw debut with a 6-2 6-1 trouncing of American world No.106 Hailey Baptiste, the tournament's third seed.
Hon advanced with a 7-6 (7-4) 6-7 (2-7) 6-4 victory over Russian top seed Kamilla Rakhimova for her best grand-slam result since the 2020 Australian Open.
World No.180 Aiava upset Croatia's 2016 US Open quarter-finalist Ana Konjuh 6-3 6-2 for her third straight victory over a high-ranked rival this week.
After falling in the final round of qualifying last year, Birrell went a step further with a 6-3 6-3 win over 15-year-old American wildcard Julieta Pareja.
Rodionova, 34, qualified for a major for the first time since 2019 Wimbledon, with a 6-4 6-2 defeat of Thailand's Mananchaya Sawangkaew.
And 28-year-old Tu gallantly saved two match points in an epic 3-6 6-1 7-5 win over Dutch sixth seed Jesper de Jong in the biggest win of his grand slam career.
The world No.188 joins de Minaur, Popyrin, Jordan Thompson, Rinky Hijikata, James Duckworth, Thanasi Kokkinakis, Chris O'Connell, Max Purcell, Aleksandar Vukic, Adam Walton and Skoolkate in the men's main draw.
