Sydney's got one too, but
they can't spell it.
Richmond is particularly popular - in fact a question I asked in a quiz I organised a year or two back was "which is the only Australian state which doesn't have a town or suburb called Richmond?".
The most incongruous contrast between an Australian placename and its British namesake is undoubtedly St. Kilda, whose name is shared by the most remote island of the Outer Hebrides and a very non-remote suburb which is Melbourne's traditional home of sex, drugs and rock n' roll (although it's a bit tamer than it once was).
