Its a shame more Americans don't spend time in Melbourne
You have the Penguin Parade, Ballarat for historical reinactements, Great Ocean Road where I saw REAL wild koala and great unspoiled beaches, The various gardens around Melbourne, trams, Dandeong ranges, Yarra wine country, Grampians for yet more wildlife(although suffering from forest fires). Its very easy for this American to say he spent 2 1/2 weeks in Australia but didn't see Sydney and didn't really miss it.
