The New Zealand Warriors, Brisbane Broncos, Sydney Roosters and St George-Illwarra Dragons will all field women's teams in the first NRL Holden Women's Premiership.
NRL Chief Executive Officer Todd Greenberg says that geographical location played a big part in deciding what teams would be represented.
Alongside New Zealand, the NRL has covered the two main rugby league states in New South Wales and Queensland.
Former New Zealand women's player Tarsh Ieremaia says that having the most elite players at one tournament will only increase interest from other clubs.
"It's what you want for the first year. You want to get a lot of teams buying into it and hopefully next year they do expand."
Ieremaia is also confident that the Warriors will be competing at a very high level.
"We have quite a lot of depth. Because there's certain rules as to how many international players you can have in each team, I think the players just underneath our international players are just as strong."
Two NRL clubs missed out on being selected for the tournament, the South Sydney Rabbitohs and the Cronulla Sharks.
