living in country victoria, australia, we call it 'toilet' as mostly we have toilets separate from the bathroom. People who are "sophisticated' call it a bathroom! causing some confusion as, when asked, they are directed to the bathroom! In our house hold it is commonly referred to as the dunny, though strickly speaking this is a bit course. It is also known as a loo, also a bit course. powder room, restroom & john are also used but not often. Ladies and Gents are used often for public areas. My favourite is still the dunny! as it is very australian.
