Premiership matches will be held in Mudgee, Tamworth, Bathurst and Gosford next year, as well as Gladstone, Toowoomba and Cairns.
It means the 2018 season will include the most number of regional locations in NSW and Queensland in the history of the NRL Premiership.
The Gold Coast Titans will take two matches to regional centres (Gladstone and Toowoomba), while South Sydney will continue play one of its matches in Cairns.
