Hard to tell. It is like mens footy, in that a player can dominate at a lower level, but may not be able adjust to a higher level They have said that SA womens footy is improving, however Cramery dominated the SA selection game, but was average to below average in the AFL game. Goding the SA ruckwomen got pantsed, lost pretty much every tap, had no impact around the ground.Seems like you have a good understanding of the women's game. If there was a national competition, what would be the percentage's of top line players in each state?
The SA youth girls have improved, and Qld only lost the final to Vic metro by a couple of goals, so that may flow on to the senior ranks. However you wonder what effect the standard of the senior comp has on their development once they get there.
So I would say roughly as it is now for the next few years. 80% will come from Vic/WA, then a handful from Queensland and a sprinkling from the rest of the the country. This will change but it is hard to tell how. There will also be a pull factor for girls who want to take it seriously to go to the VWFL premier division or WAWFL seniors to play for the top clubs. These are the places setting the standard, and girls who do well there get noticed.
