Following record-breaking passenger arrivals in 2025, Melbourne International Airport in Victoria, Australia, has unveiled plans for a $4.5 billion expansion.
Five new gates, expanded check-in, and increased baggage claim capacity are among the projects announced. Funded through private investment, the airport expects the expansion to be completed over several years, as building work needs to fit around 24/7 operations. Alongside 2025’s record numbers, January 2026 was the airport’s busiest-ever, with 1.26 million international passengers processed over the month.
The greater footprint will provide more space for Melbourne’s ever-increasing passenger numbers, and give airlines the flexibility to schedule more flights out of the gateway. Capacity will be further enhanced when the airport’s third runway is completed in 2031.
Melbourne Airport Chief Executive Officer Lorie Argus said:
We’ve spent several months working collaboratively with the airlines to ensure these plans meet their needs, while also delivering an improved experience for our travellers in both arrivals and departures. Our investment in new infrastructure will deliver much needed extra capacity, but it is only part of the puzzle. We’re keen to work with the federal government on upgrades to border processing technology and facilities to help further improve the arrivals experience for international travellers. With just one average daily international flight worth $190 million to the Victorian economy every year, these investments will help facilitate more services and secure thousands of jobs around the state.
Australia’s Assistant Minister for Citizenship, Customs and Multicultural Affairs, Hon. Julian Hill MP, added:
Australian airports are critical infrastructure – connecting people with family, friends and work, and welcoming visitors from across our nation and the world. Demand for domestic and international travel at Melbourne Airport is growing rapidly and Victorians and visitors alike will welcome these improvements which can’t come too soon. I welcome Melbourne Airport’s work to streamline passenger movements across domestic and international terminals. Australian Border Force will continue working closely with industry partners to improve passenger experience and ensure Australia’s airports are fit-for-purpose over the coming decades.
