FTR - I played cricket in the same team as a 16 year old girl last year. She regularly took multiple wicket hauls, and is (I think...) in the squad for NSW and VIC U/18's. (There are some perks to living on the border.)
The relevance is that when my daughter found out that "girls can play cricket too" she began to take more interest in watching cricket.
Now - if she sees that "girls can play footy too" - she will most likely watch more footy. If that is the case - I would hate to think that she barracks for Melbourne or the Bulldogs because they have a team in the comp and we don't.
