But the Dolphins proved the standout and the new team will be based at Redcliffe, north of Brisbane, and will join the competition from 2023.
The Dolphins have agreed to invest $1m per annum on grassroots rugby league and pathways as well as an additional $1m per annum on women's rugby league pathways and development.
The expanded 17-team competition means the NRL premiership season becomes a 26-round competition, with every team continuing to play 24 games. All teams will receive two byes during the season, with the number of regular season games increasing from 192 to 204.
NRL chief executive Andrew Abdo said the expanded competition would create more opportunities for the rugby league ecosystem.
"This is an exciting day for our game. There will be more opportunities for our players in 2023, more games of rugby league to watch for our fans and more investment in pathways for our grassroots participants,'' he said.
"It's also an excellent outcome for our partners and sponsors who have additional exposure from 2023.
"The structure of the season means there will be 12 more games played every year and all clubs will receive two byes, which assists the workload management of our players."
