The Silver Ferns will next month face an Australian team going through a rare period of turmoil.
The usually settled Diamonds programme has been thrown into disarray following their shock 57-47 loss to the Silver Ferns in the Quad Series finale two weeks ago.
That sealed the demotion of Australian vice-captain Madi Robinson, who has been dropped for the four-test series, while several other stars have been put on notice.
In a strongly-worded statement, Diamonds coach Lisa Alexander left no room for interpretation over Robinson's omission.
"We will be working with Madi on the areas of her game requiring improvement and she will continue this work at home base," Alexander said in the press release accompanying the team naming.
