The Southern Steel have axed assistant coach Natalie Avellino after an apparent falling out with head coach Janine Southby.
The pair last year shared the co-coaching duties, but this season the franchise opted to revert back to a traditional coaching structure.
But, according to a statement from the franchise, differences in "coaching philosophies'' between the pair had caused tension, forcing the Steel to take the remarkable step of ending the arrangement four weeks into the competition.
A review conducted recently by newly-appointed Netball South chief executive Sue Clarke showed the coaching arrangement was not working effectively.
"Both Janine and Natalie agree the coaching relationship is no longer tenable and the decision has been made for Natalie to finish with the franchise,'' Clarke said.
