The problem with that approach, Polly, is it is doomed to failure.
Read what was said about the lack of funding and I disagree with you about the AFL putting funding into things that 'appear to be morally right'. They will throw funding into something that makes them a quid. They will throw money into things that either make them look good or help them to dodge bad publicity.
There is not much in the way of ethical conduct coming out of the AFL. This is the same organisation that essentially cleared Essendon for running what amounts to be an uncontrolled experiment on players using substances that the club and the AFL seem unable to identify.
Telling clubs to emply women coaches without specifying some form of equality in salaries with their male counterparts will attract only those who find the lower salaries attractive. If you want the best women to apply, you need to pay them. The article lists the salaries paid to the two womens head coaches and that was, in both cases, less than what they could have been paid elsewhere. Cowan took a pay cut to go to Freo and Goddard would have been paid more than 100k pa in the AFP, so she also took a pay cut.
You won't attract the best female talent when you don't pay them more than they would get elsewhere. You don't do that to the blokes so why do that to the women?
What you will get is anything but the best and then people will point to the calibre of women coaches and compare them unfavourably to male coaches.... a self fullfilling prophecy for failure.
Mandate minimum salaries to match the male ass. coaches at least and then see what sort of talent you can attract.
