"With the exception of Goonoo Goonoo (and others I suspect), it is quite acceptable to only use one word in conversation when referring to these places - eg Wagga, Burra etc

Just thought of another exception to the rule - the town of Woy Woy in New South Wales. Made famous by the fact that the Goon, Spike Milligan's, mum lived there. Spike was oft seen walking the streets therabouts - or on the train from Sydney. Mate of mine had a lengthy chat with him one day on the train (we were in out teens). Got off at our station saying over and over, "I've been talking to Spike Milligan, I've been talking to Spike Milligan".

Famous or not, the place is never known as 'Woy'.
