Australia's batters crashed to the nation's lowest women's Twenty20 total in a humiliating loss to New Zealand.
Chasing 114 runs to win, the Australians were bowled out for 66 - handing a 2-1 series triumph to the Kiwis.
Australia's previous lowest women's T20 total was 73 all out against the New Zealanders in 2010.
Earlier, New Zealand's batters suffered a collapse of their own, losing four wickets in six balls in their total of 113-8.
Australian legspinner Amanda-Jane Wellington took 4-16 from four overs, including three wickets in an over - the first the prized scalp of Kiwi captain Suzie Bates who top-scored with 31 from 34 balls.
