Each week, 600 scheduled passenger services depart Sydney's world-class international airport, providing over 169,300 seats across 37 airlines. The large number of international passenger airlines operating out of Sydney, compared with other Australian cities, provides greater flexibility and choice for overseas business travellers as well as tourists.

Sydney is the dominant provider of logistics and transport services in Australia. More than 10.1 million international passengers moved through Sydney Airport in 2006-07, around half of the Australian total and more than double the share of the next largest international airport. Sydney Airport is critical to the State's role as the largest exporter of business services from Australia, with New South Wales accounting for around 70% of national exports of financial, insurance and professional services.

Almost 50% of Australia’s international air freight and 60% of international mail was handled by Sydney Airport in 2006-07. The airport is supported by significant clusters of customs agents, freight forwarders and integrators as well as transport/trucking companies.

New South Wales has three large sea ports connected to an extensive network of rail and road infrastructure. Almost $55 billion worth of cargo is traded through Sydney ports every year. The Port of Newcastle is the largest export coal port in the world. In 2006-07, almost 81 million tonnes of coal and 139,000 tonnes of aluminium were exported from the Port of Newcastle. Port Kembla, south of Sydney, is a multi-functional port with facilities for bulk goods port handling including commodities such as iron ore, coal and grain. The port is currently undergoing major expansion that will see general and break bulk cargoes, containers and vehicle handling becoming increasingly important.
