"Other sports, such as boxing, have weight categories for similar reasons.
Ms Mouncey ostensibly weighs 110kg. Serena Williams, surely one of the most powerful female athletes competing currently weighs, according to the internet, somewhere between 70 - 85kgs, some 25kgs less than an average man.
It would be very unlikely that a female AFL player would be anywhere near the height and weight of Ms Mouncey."
The average weight for an Australian man is 85.9kg. Tennis isn't AFL. Neither is boxing. Compare like for like, with correct numbers, or the comparisons are irrelevant. Female rugby players frequently hit the 85 - 95kg mark. There is no upper weight limit in the mens' game either, hence the strong possibility that a 85kg fly half could get tackled by a 130kg+ prop.
