Anyway, couldn't you grow such a citrus plant outside where you are in Oz?

Not wishing to have a dig ;-) but ironically I'm sitting in front of
the screen, sipping a glass of Shirnoff that has several chunks of
lime floating with the ice . Nothing unusual about that, but before I
poured the 'snifter', I popped outside to pick the lime and there are
plenty more on the bush for future forays into ethyl oblivia!
