Western Sydney Airport vs Avalon: How the New Hub Compares 2026

Western Sydney International Airport (WSI) is set to welcome its first commercial flight this weekend, marking a major milestone for Australian aviation. But it's not the first secondary airport in a capital city — Melbourne's Avalon opened over two decades ago with similar ambitions. So how do the two compare, and what does WSI's launch mean for the future of air travel in Australia?

A Tale of Two Secondary Airports

Both WSI and Avalon share striking similarities: they are located roughly 60km from their respective city centres, have comparable footprints, and their first commercial flights are operated by Jetstar. Yet, both airports are quick to point out that they are far from identical.

Avalon's CEO, Ari Suss, dismisses direct comparisons, saying it's "not really comparing apples with apples." A WSI spokesperson goes further, describing the two as "conceptually chalk and cheese." These distinctions hint at deeper differences in vision, infrastructure, and market positioning.

Why Avalon Never Quite Took Off

Avalon, built in 1952 as a military airfield, has struggled to become a major passenger alternative to Melbourne's Tullamarine. Despite grand plans and a stated ambition in 2015 to become "the nation's leading secondary airport," Avalon has never reached its full potential.

When asked if WSI might overtake Avalon in that ambition, Suss remained focused: "I'm concentrated on Avalon." His response underscores the competitive tension between the two airports, even as they downplay comparisons.

Key Differences That Set WSI Apart

While both airports are far from their city centres, WSI benefits from being part of a broader greenfield development and is backed by significant government investment. Its terminals have been architecturally lauded, and the airport is designed to handle future growth with cutting-edge technology.

Avalon, by contrast, has evolved more organically, with limited public transport links and a smaller route network. Its location near Geelong gives it a different catchment area, but it has struggled to attract major airlines beyond Jetstar.

• Location: Both are ~60km from city centres, but WSI serves Sydney's fast-growing western corridor.
• Ownership: WSI is a government-backed project; Avalon is privately owned by Linfox.
• Infrastructure: WSI features new terminals and technology; Avalon has seen incremental upgrades.
• Airline mix: Both rely on Jetstar for initial flights, but WSI aims to attract more international carriers.
• Growth potential: WSI is designed for expansion; Avalon's growth has been slower.

What This Means for Travelers

For Sydney residents, WSI promises to ease congestion at Kingsford Smith Airport and provide more travel options, especially for those in Western Sydney. For Melbourne travelers, Avalon remains a convenient alternative for those near Geelong or the western suburbs, but its limited routes mean it's not yet a true second hub.

The launch of WSI could also put pressure on Avalon to step up its game. Competition between secondary airports can lead to better services and lower fares, benefiting consumers.

The Road Ahead

WSI's opening is a bold bet on the future of Sydney's aviation needs. Whether it becomes a true second hub or follows Avalon's slower trajectory remains to be seen. What's clear is that both airports are vying for relevance in an increasingly competitive market.
