Clayton South is a suburb of Melbourne - I could quickly find the local population figure for 1966. Melbourne is Australia's second largest city and is the capital of Victoria.
Victoria is known for its discerning, thoughtful and sensible residents - it was the only state to vote against the constitutional monarchy in the 1999 Australia republic referendum. Perhaps hoaxers would not find the necessary gratification living in such a culture.
The Victorian rural lifestyle is also highly desired. It is said to be because the state government has the most effective drop-bear management program in the country.
