Australian goal shooter Caitlin Bassett says the Diamonds cannot afford another lacklustre performance if they want to beat arch-rivals New Zealand in their opening netball test in Perth on Sunday.
The Australians completed a three-game series sweep against England on Sunday, but won the final match by only four goals.
Bassett was Australia's world championship hero in Singapore in July, shooting the winning goal in extra time of the final against the Silver Ferns.
Bassett believed the Diamonds made too many errors and were unable to convert enough of their turnovers.
She said that to win again, they would have to vastly improve.
