Petticoats rule!

Back in the 1950s I'd never have thought it possible.
We New South Walers now have a female head of state (Her Maj), a female representative of the Crown (teh G-G), a female Prime Minister (all hail Gillard!), a female State Governor (hat tip to Marie B) and a female Premier (K-K-Keneally acting on behalf of her hair).
This has to be the ultimate hat trick.
