Sydneysiders think little of claims by Melbourne. A recent world survey put Sydney at ninth as the world's most attractive cities. Melbourne didn't rank in the ten. The problem was that the researchers only knew of Sydney as an Australian city. This says a lot about how outsiders view Australia.
Most capitals have the highest population of any other city in a country. Sydney clearly has the highest population. Though many Australian companies choose Melbourne as their base, overseas businesses go to Sydney. Furthermore, Sydney is the main distribution point for Australian news to the world.
Thankfully, tourists from other countries do not come to Australia to experience city life. They get that at home. They spread themselves broadly across the country in choice of vacation destinations. There is not much doubt that tourists enter the country through Sydney. This does give a "tourist dollar" advantage to the city. The Gold Coast, Great Barrier Reef and Melbourne would be fly-on destinations for most visitors.
