The Adelaide Thunderbirds have upset the New South Wales Swifts by 52 points to 38 in their trans-Tasman netball semi-final in Sydney.
The Swifts, the undefeated minor premiers, now have to get past the winner of Monday night's all-New Zealand derby in Auckland, where the Waikato Bay of Plenty Magic and the Southern Steel will fight it out for a place in the preliminary final.
The Thunderbirds now get two weeks off to prepare to face the winner of that game in the final.
