The fallout following the exit of Donnell Wallam and Remi Kamo, the on-court bookends for Queensland Firebirds, has led to claims of a "toxic culture" inside the Suncorp Super Netball club.

Netball Australia is conducting an investigation of the club's culture after Kamo, a Maori woman who was born and raised in Australia, made a formal list of complaints over the treatment of Firebirds players.

Kamo is reportedly concerned about the next generation of Firebirds players from diverse or marginalised backgrounds and their ability to thrive in a transparent environment in its Brisbane base.

The 30-year-old told the investigation the club failed to support athletes' wellbeing and management gaslighted their own players, leaving them feeling dis-empowered.

The investigation's line of inquiry focuses on the inner workings of the Firebirds while also covering the mid-season dismissal of its coach, Bec Bulley, following player unrest just two-and-a-half years into her four-year contract.

Bulley's coaching appointment coincided with Kamo joining the club, however the goal keeper hesitated to re-sign for another two years at the expiration of her first deal, electing to remain a Firebird for a single year with the understanding Bulley would remain coach.

New Zealander Kiri Wills has since been appointed Firebirds head coach for next season.

There is no suggestion from National Indigenous Times that Bulley was at fault.

Netball Australia is keeping the details of the issues close to its chest, having declined to answer questions while the club's internal probe plays out.

"Netball Australia can confirm it recently received a complaint and we took immediate action (with this investigation)," a Netball Australia spokesperson said in a statement.

"Netball Australia is seeking further information to progress the inquiry, as well as offering support, and assurance that the complaint is being taken extremely seriously.

"The investigation process will be thorough and conducted confidentially, and therefore we cannot comment further at this time."

Netball Queensland, the state body that runs the licence for the Queensland Firebirds, was also unwilling to address the accusations while cooperating with the investigation.

"As the matter is under an ongoing investigation by Netball Australia pursuant to the netball integrity policy framework, conduct and disciplinary policy, Netball Queensland and its employees will not be making any public comment on this matter," Netball Queensland said in a statement.

Kamo, who was backed up by and speaking on behalf of Wallam, are the only two Firebirds to condemn the management of the club.

Rival Suncorp Super Netball players are said to have also offered messages of support to the Firebirds.

Former teammates of the axed pair have remained silent and according to Kamo, have refused to speak out over fear of the consequences.

But Wallam and Kamo appear to have copped much of the brunt of the team's off-season actions.

Neither players were offered new contracts for the 2025 season despite performing strongly throughout a poor 2024 Firebirds campaign that landed just four wins from 14 matches and a second-last finish in the eight-side competition.

Wallam continued to dominate in attack, the goal shooter scoring the second-most goals (556) in the league, the most by an Australian, the second-most offensive rebounds (47), again was the most by an Australian, and scored the fifth-most super-shot goals (50).

Kamo was not one of the standout defenders in the competition, however the workhorse had 17 more intercepts and 20 more defensive rebounds than her former Firebirds teammates.

Despite their performances, the two 30-year-olds were the only women on the club's roster that were told their services were no longer required at season's end.

The departing teammates will now head to New Zealand's domestic netball league to play for separate sides.

Both players have since stopped following the Firebirds social media and did not attend the end-of-season club awards dinner.

Neither player won any of the five awards on offer more than a month ago, but despite their absence from the dinner, the Firebirds management still "thanked" both players for their contributions to the team.
