Yes really, parity in pay, I can see it now,.just like in tennis. Difference is the NRL is broke already.
Hate to break it to you, but tennis does not have parity in pay. Prize money for majors is the same, but that is a policy decision of the Majors. Apart from that, the women play a different circuit with an entirely separate pay structure.
AFL does not have parity, and does not have parity as a goal, and there is no prospect of it.
Soccer does not have parity, and does not have it as a goal, or any prospect of it.
Basketball ditto,
The only sport you could say it of is Netball, and even there, it lags all the other mens sports at the top end.
The NRLs national womens league is starting well behind those other sports, and for the first 2 or 3 years, what the women will get would probably be better described as compensation rather than pay.
What is it that makes you think the NRL, with the smallest and newest of the national leagues, will sit down and strike a pay deal with women that is beyond their budget, and capacity to pay?
