The Wallaroos' long wait for their first win over New Zealand continues with the Australians outclassed by the world No.1 side in their Perth Test.
The Black Ferns hadn't lost in 17 clashes since 1994 and added another thumping victory with a 47-10 scoreline.
In the first match of Saturday's double header at Optus Stadium, also featuring the Wallabies and All Blacks, the Black Ferns ran in eight tries to two.
Both of the Wallaroos' tries came in the second half through winger Lori Cramer.
Her first was an 80m dash after the ball popped out of the ruck, while credit for the second must be shared with exciting teenaged centre Alysia Lefau-Fakaosilea, who managed to get the final pass away in heavy traffic.
The Australians went into the match with high hopes after sweeping their two-Test series against Japan but they found the Kiwis a big step up.
The Black Ferns dominated the physical contest, while the home side's lineout struggled throughout the match, losing seven of their own throws.
The Wallaroos didn't help their cause with some poor ball security proving costly and limiting their ability to build pressure.
New Zealand raced to a 22-0 halftime lead with No. 8 Charmaine McMenamin collecting a double.
They showed off an array of skills with McMenamin's first coming through a driving maul off a lineout before she finished off a brilliant counter-attack off a poor Wallaroos kick.
Winger Ayesha Leti-I'iga proved a constant threat for the Black Ferns and was rewarded with a 73rd-minute try.
Despite Wallaroos skipper Grace Hamilton's valiant efforts all match, they still have plenty of work to do to close the gap on the world champions before next Saturday's return clash in Auckland.
