The only successes were Val Smith, who beat Kelsey Cottrell 21-16 in the singles, and a second-round 13-all draw by the four (skipped by Jo Edwards) with an Australian team skipped by the outstanding Karen Murphy.
That left the Kiwi women with a chance of stealing the test, provided they could win both matches in the third and final round.
But that depended on the triple winning for the first time in the three tests and that proved to be a hope in vain.
Sandra Keith was moved from two to skip instead of Mandy Boyd, but that didn't change their fortunes. A flat performance saw the New Zealanders crushed 19-4 by an on-song Australian display in which Murphy at skip was again an inspiration.
New Zealand's two most experienced players, Smith and Edwards, looked to have a chance in the pairs with Cottrell and Rebecca Quail. Coming to the last of the 15 ends, Smith and Edwards led a tight match 8-7, but then dropped two shots to lose 9-8.
The Australians also dominated in the development and under 18 sections, with New Zealand's only success in the under 18 men's.
