FannyCornforth
Like 'cheerio' then?
Originated from hooray, I think, FannyC, used by men working out bush, more a kind of adieu (farewell, hope to see you soon).
Then I think it was picked up by a radio show presenter and he used it as his 'signing off' and thus it became popular down South.
One of the vagaries of the Australian language, like calling someone with red hair "Bluey".
