The major overhaul will be rolled out over the next few years – adding five more aircraft stands, upgraded baggage halls and new lounge spaces to the 24-hour airport

If you’ve battled Melbourne Airport’s international departures hall at peak hour lately, you’re not imagining it – Melburnians are officially flying again. Thankfully, following its busiest summer for international travel on record, Melbourne Airport has unveiled official plans for the expansion of its international terminal.
According to the team, more than 1.26 million international passengers passed through the airport in January alone – a new monthly record. As Melbourne’s population swells and our collective appetite for long-haul escapes rebounds, the airport is upping its capacity to help get us in the air. The intention to expand was announced last year, and now we've got extra details of the $4.5 billion project.
The multi-stage expansion will see both the international check-in and baggage claim halls significantly expanded to better handle growing passenger numbers (and, ideally, ease those pre-flight queues). Five new gates will be added to the existing international pier, giving airlines more flexibility to schedule flights to more destinations at the times people actually want to travel. In practical terms: more options, fewer awkward layovers.
There will also be five new aircraft stands – capable of accommodating either five wide-body or eight narrow-body aircraft – alongside expanded waiting areas, upgraded lounge facilities and improved shopping options. Arrivals aren’t being forgotten either, with extra baggage carousels, more space for border agencies and a larger waiting area for meeters and greeters.
The expansion is being enabled by the opening of new pick-up and drop-off zones in the T123 Transport Hub in September 2026, which will allow the international terminal to extend into the existing forecourt. Preliminary works on the first stage will kick off once the airport’s new road network opens later this year.
Melbourne Airport CEO Lorie Argus says the upgrade is about future-proofing. “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, noting that the works will complement the airport’s third runway, due to open in 2031.
And the stakes are high. According to Argus, just one average daily international flight is worth $190 million to the Victorian economy each year. More capacity means more flights, more choice for travellers and exporters, and thousands of jobs supported across the state.
Of course, building inside a live, 24-hour airport is no small feat, so the privately funded project will roll out over several years. But for frequent flyers – and anyone who’s ever queued for customs after a red-eye – the promise of a smoother arrivals and departures experience can’t come soon enough.
