Queensland officials have said the three state teams could host home games and play between states.
“I said I was as eager as anyone to see the return of the NRL and I thought so,” Queensland Premier Annastacia Palaszczuk told reporters.
“The only condition was that it did not jeopardize our excellent work containing the spread of COVID-19 and the Chief Medical Officer of Health indicates that the NRL plan is workable.”
Without Queensland’s green light, state teams would have had to move to New South Wales for an extended period of time, a prospect frowned upon by some players who would be far from their families. Ten of the 16 teams in the competition are based in New South Wales.
A May 28 start would make the NRL one of the first leagues in the world to resume competition, but some hurdles remain.
The only New Zealand team in the competition has not yet been granted permission to travel to Australia, Prime Minister Scott Morrison said on Friday.
The Auckland-based New Zealand Warriors have agreed, in principle, to settle in Tamworth, rural NSW, to allow the competition to continue.
The Victoria State-based team from Melbourne Storm could also be forced to relocate to New South Wales if state authorities refuse to ease travel restrictions.
