Australia recorded their record highest score against New Zealand as they thrashed the Silver Ferns 68-48 in their Quad Series netball clash in Sydney on Sunday.
It was also the Diamonds' biggest winning margin over New Zealand in 12 years.
Susan Pratley made 29 of 32 attempts while fellow Australian shooter Catherine Cox made 29 of 36 in front of 13,640 at Allphones Arena.
The Diamonds surged out to lead 19-9 at quarter-time and increased the margin at every break.
After three rounds, they are now the only unbeaten team at the midway point in the Quad Series which also involves England and South Africa.
