"My morals are: you do not belt a woman. That's just how it is.
"I'm a proud ambassador of White Ribbon and I just don't respect any man that goes out and belts a woman. It's just not right.
"If we're going to sit there and talk about our game changing and our culture changing, if you're going to come into the game and get paid ridiculously well and you can't change your morals because 'we've got to change the culture' — you've got to change the culture mentally. You're the one who's got to turn up and say 'I don't want to belt women, I want to be a different person, I want to be a role model' and if you don't want to do it, then don't play our game.

"So if I experienced it as a kid and I don't want to see it and I don't want to see my daughter go through it, I'm the one who's got to make the change. No one else is going to make me change unless I make the decision to do it.

"You either believe in it and you buy into it, or you're just a grub. That's my personal opinion."
