Why another airport?
Meeting Sydney's future aviation needs
Sydney (Kingsford Smith) Airport cannot meet the future aviation requirements of Sydney alone. With demand for aviation services in Sydney set to double over the next 20 years, a new airport is required to cater for this growth.
Demand for aviation services in the Sydney region is forecast to double over the next 20 years. Even if operational restrictions were removed at Kingsford Smith, it could not meet Sydney's long-term aviation needs.
More than two million people live in Western Sydney, meaning that it would be Australia's fourth-largest city and third-largest economy in its own right. Another million people are expected to move into the region by the 2030s.
The Western Sydney International (Nancy-Bird Walton) Airport will help support this growth and connect businesses to national and international markets. It will deliver world-class transport systems, improve business links and provide economic benefits.
