KanguerillaGirls was inspired by the wonderful guerrilla girls who run fantastic, fun, yet important feminist campaigns in America. In the guerrilla girls FAQ they answer the question "how do I become a guerrilla girl?" by saying that you don't. You start your own thing.
"...we ask that you use us as a model: think up your own name and your own outrageous identity and put up a couple of posters about an issue that is important to you. If it works, do it again. If it doesn't, do it again anyway."
So here we are, in Australia, doing our own feminist activist thing.
