In Australia, approximately half of the country's air freight arrived or departed from Sydney, with the rest spread across Melbourne, Brisbane and Perth. Less than five percent landed or took off from other cities.
Over the last couple of financial years, there is a bias towards imports by air in Sydney, Melbourne and Brisbane. In each of these cities, imports were worth around four times the value of exports. However, for Perth this trend is reversed; exports by air from the city had a value of around double that of imports.
When considering trade volume, the import volume was higher at Sydney airport; Melbourne, Brisbane and Perth airports all had a higher volume of exports.

These products accounted for nearly 30 billion Australian dollars in value.
