Yeah I guess that's true in some ways, although Melbourne and Sydney aren't that unpredictable after a few years living in either place.
Melb cops a lot of shit for the whole 4 seasons in one day thing but I've seen the same thing in every state.
Oh indeed, though I never quite got used to Sydney, even though it was less chaotic than Melbourne's weather patterns.
I've never really experienced this in W.A. myself. You have?
