Sydney's second airport will soon be up and running. How different will it be to Melbourne's Avalon?

Western Sydney International (WSI) is set to begin commercial flights this weekend, challenging Avalon’s long-held position as Australia’s leading secondary airport. The first WSI commercial flight departs Sunday from its architecturally praised terminals, with Western Sydney positioned to relieve congestion at Sydney’s Kingsford Smith and offer more competition. The article contrasts the two airports: Avalon, which opened passenger service with Jetstar and has a planned capacity of 1.2 million passengers annually, suspended international routes for six years and currently offers only Bali. WSI targets up to 10 million passengers a year at launch, with expansion plans to reach 80 million by 2060.
