The Victorian government has stepped in to fill a $15 million funding gap for the cash-strapped sport after mining giant Hancock Prospecting withdrew its support.
Visit Victoria will sponsor Netball Australia for the next four and a half years in a $15m deal, Premier Daniel Andrews announced on Monday.
Under the deal, which runs until June 2027, next year's Super Netball Grand Final will be played in Victoria.
The Diamonds will also wear Visit Victoria branding on their team kit and play five test matches as well as hold training camps between 2023 and 2026.
Hancock Prospecting withdrew its $15m in funding to Netball Australia after a player-led revolt over the track record of Gina Rinehart's father on indigenous issues.
Mr Andrews described the sponsorship deal as a coup for the state.
"Obviously there was a sponsor. That sponsor was no more so there was a gap and Visit Victoria raced to fill it," he told reporters.
"Other states wanted this but Victoria secured it."
