Australian captain Caitlin Bassett has blamed the Giants rather than rule changes for her decision to play in New Zealand next year instead of the Super Netball competition.
The Diamonds centurion and the Giants confirmed on Thursday she wouldn't see out the final year of her contract and would play with the Waikato Bay of Plenty Magic.
Despite being the starting Test shooter, Bassett got limited court time in the Australian competition this season.
It was initially put down to the introduction of the Super Shot, which isn't used in New Zealand, where teams can score double points by shooting from a zone at the back of the circle at the end of each quarter.
However other sides successfully used holding shooters in their line-up, leading to rumblings about Bassett's relationship with Giants coach Julie Fitzgerald.
Bassett didn't take the court at all in the final three games of the season, although she was injured before the Giants' last-round draw, with Fitzgerald preferring England's Jo Harten and rising star Kiera Austin.
A frustrated Bassett said it wasn't the Super Shot that prompted the move overseas, but her desire for more court time to ensure her international career continued.
A two-time World Cup winner, she was recently named in the Diamonds squad to take on New Zealand in early 2021.
"I've had great conversations with key people within the Diamonds programs and we all agree that court time is essential for my development," Bassett said.
"My intention is to be a key part of our Birmingham Commonwealth Games team in 2022, and I'm looking forward to continuing to work with the squad while playing for the Waikato Bay of Plenty Magic next year."
Diamonds coach Stacey Marinkovich said she was "disappointed" to see Bassett leave Super Netball, but her Australian spot wasn't under threat.
"While we are disappointed that Caitlin has decided to leave our domestic competition, we acknowledge and value her contribution to the league over many years and respect her decision to move to the New Zealand competition," Marinkovich said.
"Caitlin is a valued member of the Origin Diamonds squad and we look forward to working with her and the rest of the group as we prepare for the resumption of international competition in 2021."
Despite the Giants finishing sixth on the ladder, Bassett was told by Fitzgerald things were unlikely to change next year - and they agreed it would best if she found another club.
"Caitlin and I had some open and honest discussions at the back half of the season and we both agree that the time is right for her to explore other opportunities," Fitzgerald said.
