Australians generally spell the British way.

Way to colonise us, guys.

I'm not bothered by 'color' if I see it, but I'd definitely feel as if I'm in the wrong if I wrote anything but 'colour'. Arguing about how pronunciation is affected by spelling is silly. This is ENGLISH we're talking about. We're spelling virtually the same as our 15th century counterparts were but we sure don't talk like them anymore.

If I wanted to spell words how they're spoken, then as an Australian, I'd be spelling 'sauce' and 'source' the same, 'park' would become 'pahk', 'paper' -> 'paypah'

We don't like R's.
