Queensland health minister Steven Miles criticised the NRL for changing its own plan around flu vaccinations as it bids to restart the season.
Several players, most notably Gold Coast Titans second-rower Bryce Cartwright, have refused the flu vaccine as the NRL tries to get back underway on May 28 amid the coronavirus pandemic.
Federal authorities, including Australian prime minister Scott Morrison, have pushed for a 'no jab, no play' policy, but a waiver clause for NRL players not to receive the vaccine is reportedly being revised.
Queensland gave the league the green light to resume, but Miles is unhappy with the NRL's latest change.
"This was their plan, they came up with this, they put it to us," he told the ABC on Friday.
"Jeannette [Young, Queensland chief health officer] assessed it as being a good plan, and one that was safe.
"It's their plan and they have to implement it."
Miles added: "It's not a good look frankly that so soon into this agreement, they've not been able to implement their own plan … they can't just arbitrarily change it and not tell her."
Australia has seen more than 6,800 cases of coronavirus, including 97 deaths.
