My rough calcs are that each club would need about an extra 7-8 mill/y to fund the pay of the AFLW players to something around 150 average with top players earning 3-4 times that.
22 of the 30 players averaging 150K (some more, new recruits less like in the men's) = 3.3 mill.
8 players between 300-800 (top player) average around 500K = 4 mill
total of about 7.3 mill.
The stadiums are paid for, clubs have already built facilities for the women, AFLW teams already have good paying sponsors, their staff are already paid for with pays only held back by the AFL's own softcap. It's just more money needed for the players.
So a club like WC/Hawks/Richmond with 100K members paying about 800/year or so on average instead pays 900/y. Extra 10 mill. Clubs with 50K members extra 5 mill. AFL averages it out as they always do and there you have your rough calculated 7 and a bit mill to pay the female players.
Members pay 10% or so more but get a second game of their team a fortnight, of fully professional players, double header maybe, in a proper stadium in front of large crowds. Better chance of leaving the stadium with at least one win and happy.
No male player needs to give up a cent.
Rough calcs but you get the picture. It's not outside the realms of possibility very soon.
Not all members would be interested and many couldn't afford it. With inflation coming like a freight train that plan would be adding another 10% on top of other costs thats have increased anywhere from 7-80%.
What would be wrong with asking them to take the same path the men took? Get more sponsors for their game, who are coming, and play part time until they can get an increase in pay. The men played as part timers for many years. Some of the money you are suggesting Peter Matera would only have dreamt of earning, and many of the men are not earning. If there are AFLW players earning 500k then the mens pay should increase by another 30-35% across the board.
The womens game is already ahead of where the men started as far as pay, league and teams commitment.
