... or perhaps I should call it war ...
... between Melbourne and Sydney.
I lived in Sydney for 11 years, but have been back in Melbourne for the last 10. Both cities have their charms, and Sydney Harbour is a beautiful backdrop, but I far prefer Melbourne. Less razzle dazzle and more culture, better and more varied food, great open spaces.
But I guess we are lucky to have some great cities right across Australia, each with their own character. There is something to enjoy in each.
When are you visiting to find out for yourself?
