Sydney’s second airport is nearly built. But will the airlines and people come?

Fans of Australian aviation are excited about Western Sydney’s new international airport (WSI), which promises to revolutionize travel with 24/7 operations addressing growing demand for faster and more convenient flights. As a major alternative to Sydney’s existing Kingsford Smith airport, WSI aims to handle over 80 million annual passengers, potentially becoming Sydney’s largest by the end of the decade. However, its success will depend on avoiding head-on competition with Kingford Smith, managing peak-time slot restrictions, and carefully planning nighttime flights to minimize noise pollution while boosting the local economy.
