Melbourne Airport Announces $4.5B International Terminal Expansion

Responding to a record-breaking surge in international travel, Melbourne Airport (MEL) has announced a $4.5 billion AUD investment to significantly expand its international terminal. The privately funded project aims to increase capacity with new gates, an expanded check-in hall, and improved baggage systems to accommodate sustained passenger growth.

The expansion is a direct response to recovering travel demand that has surpassed pre-pandemic levels. According to airport data, January 2026 set a new record with over 1.26 million international passengers passing through the facility. For the financial year ending June 2024, the airport managed over 11 million international passengers, contributing to a total traffic figure of 35.1 million, which represents 94% of pre-pandemic levels from FY19.

Project Scope and Timeline

The core of the aviation infrastructure investment involves the addition of five new gates to the existing international pier. These new aircraft stands are designed with flexibility, capable of accommodating either five widebody or eight narrowbody aircraft simultaneously. This increased airfield capacity is critical for attracting new services and allowing existing airline partners to expand their schedules.

Beyond the new gates, the project includes a substantial enlargement of the international check-in hall, featuring modern, common-user baggage facilities. The expansion will also create more space for security screening and processing by the Australian Border Force (ABF), aiming to streamline the passenger journey. Upgrades to retail and lounge areas are also part of the plan to enhance the overall passenger experience.

Preliminary work is scheduled to commence after the new Terminals 1, 2, and 3 (T123) Transport Hub and its associated road network open in September 2026. The full expansion will be completed in stages over several years, ensuring minimal disruption to ongoing operations. The airport's official announcement provides further context on the project's phasing.

Strategic Importance and Industry Context

This terminal upgrade is a key component of Melbourne Airport's broader master plan and complements the development of a planned third runway, which is expected to open by 2031. Together, these projects represent a significant step in future-proofing the airport's capacity for decades to come.

Melbourne Airport Chief Executive Officer Lorie Argus emphasized the project's necessity. "As Melbourne grows, demand for air travel is growing too and we are investing billions of dollars to deliver the infrastructure we need to accommodate that," she said. "Increased capacity on our airfield and terminals will allow airlines to schedule more flights to more places, which will give consumers and exporters more choice."

The investment aligns with a nationwide trend among Australian airports upgrading infrastructure to handle new-generation aircraft and rising passenger volumes. This trend is fueled by the robust post-pandemic recovery in international travel, particularly from key Asian markets. Data for January 2026 shows China was the leading source of international visitors for Melbourne with 59,000 arrivals, followed by New Zealand and India, underscoring the importance of these travel corridors.

What Comes Next

With preliminary works slated for late 2026, the project will progress in carefully managed stages. The development will be closely integrated with the airport's other major projects, including the third runway. The expansion is designed not only to handle more passengers but also to improve operational efficiency and passenger processing technology, ensuring the airport remains competitive as a major international gateway for Australia.

Why This Matters

This multi-billion-dollar expansion solidifies Melbourne's position as a critical hub for international travel in the Asia-Pacific region. For airlines, it provides much-needed capacity to launch new routes and increase frequencies, fostering greater competition. For passengers, the project promises a more efficient and modern airport experience, from check-in to boarding.
