Yes, it can happen with Australian airlines, but it is definitely rarer than the US ones - the fuel charges are lower and priced differently to the USA.
There's a long thread on it on AustralianFrequentFlyer.com.au if interested, although it kinda deviates into an explanation of the concept anyway.
In general, it's still sometimes possible from Australia, eg some have managed to do it SYD-LAX, for example, although to be fair that was American Airlines.
