My view not every team will ever have a women's team and nor should it, it isn't ever going to be sustainable, so instead of NRL teams competing with each other for women's teams and development areas, I Think there should be key partnerships and cost sharing amongst specific team. This is tricky as you don't want to rule out a couple of key derby games, but I think you want to solidify support for the competition in certain areas.
To that end, I think you could go with something along the lines of:
1. South Queensland Broncos - Qld is a critical market, and the Broncos have the ability to go it alone probably, but I think a partnership with the Titans, with the Broncos the majority stakeholders would work. It would mean they garner complete support from the South and ensure the side doesn't have to compete against itself for female talent. and The logical step for expansion would be for a Northern Qld side down the track making for a great derby.
2. Western Sydney Eels. Playing out of the new stadium, a partnership of the Eels and Panthers would be fantastic.
3. St George/Illawarra Dragons. Already a merged side, this is a no brainer for mine.
4. Central Coast Bears - Throw these guys a bone, give them the female catchment from Manly to Newcastle and see if they can make a go of it.
5. South Sydney - They already have an established side I believe that are very successful, with a large catchment
6. New Zealand Warriors - The Kiwis have some solid female units running around and I don't think they should go South and try and compete with the Women's AFL. Only concern is, I imagine they'd be trying to keep costs to a minimum so the travel costs may be a factor and a bridge to far in the early stages.
If that was the case then the alternative may be the Southern NSW Raiders, a side encompassing everything South of the Shire and the Nations capital.
