So Canberra United doesn't exist? Look em up.
What about the WNBL and Super Netball, both leagues should have failed a long time ago using the logic that you and Jamberoo espouse.
BTW, it'd only cost too much if you tried to live outside your means (which is the problem with most professional women's sports BTW, always pushing for parity with the men without being willing to take the time and do the work to earn it), and you don't need the same pro-club on top of the pathway to maintain the pathway, that's just silliness, nor should it be the jobs of the pro-clubs to maintain the grassroots anyway.
To be fair, in the case of Supernetball, while pay is pretty reasonable, they have a low number of players on the roster, and only 8 teams to share the pie with. WNBL pay is improving, but again rosters are fairly small, and team numbers are limited, Similar can be said of the W-league,
Wages come into play when your fighting for the best talent with SuperW, AFLW, NRLW and A-league, as well as WNBL, Supernetball, and even WBBL and Tennis.
I think the strength of the AFLW/NRLW is not just being able to leverage existing support, but its the huge cost savings in not having to duplicate support staff, admin, facilities and equipment, while being able to pull in more female support. It enables them to absorbn more wage costs. Plus, being able to share and improve female teams in the same facility, is a proven winner with governments when it comes to facilities funding - at least in AFL majority states and Queensland.
