Sydney Airport is set for its largest upgrade since the 2000 Olympics, with a major expansion linking the T2 and T3 domestic terminals. The preliminary draft Master Plan 2045 outlines plans to create a new terminal precinct where domestic, regional, and international flights operate under one roof, supported by driverless buses connecting to the existing T1 International Terminal.

Key Points

• T2–T3 terminal expansion expected to be completed between late 2027 and early 2028
  ‍
• Project will add up to 12 new international gates, plus two additional gates at T1
  ‍
• Passenger numbers forecast to grow 75% by 2045, reaching 72.6 million annually
  ‍
• Freight volumes expected to more than double to 1.4 million tonnes per year
  ‍
• Sydney Airport projected to contribute $70 billion annually to the economy and support over 105,000 direct jobs
  ‍
• Plan integrates sustainability initiatives, noise reduction strategies, and improved passenger experience with biometric check-ins and advanced baggage handling

Project Significance

The terminal expansion is designed to meet Sydney’s growing aviation demand, even after the opening of Western Sydney International. By consolidating services in one precinct, the airport aims to increase efficiency, reduce runway congestion, and enhance passenger connectivity. International passengers are expected to grow from under 40% to just over 50% of total travellers, reflecting Sydney Airport’s strategic focus on premium international and domestic travel.

Further Details

While the project promises faster connections, improved capacity, and economic growth, it will also bring increased air traffic and noise for surrounding communities. The airport emphasises that these impacts will be managed with quieter aircraft, environmental strategies, and careful planning. Public consultation is open until 12 December 2025, allowing residents, airlines, and stakeholders to provide feedback before final approval.

The T2–T3 expansion marks a defining moment in Sydney Airport’s evolution, promising to transform the gateway to Australia’s largest city while balancing growth with responsibility.
