The $90 billion question: How many $31 tickets will the high-speed train line sell?

Australia’s ambitions for high-speed rail are often met with a mix of excitement and skepticism, and for good reason. As plans for a transformative high-speed line connecting Newcastle, central Sydney, and the city’s new international airport progress, a staggering figure looms large: $90 billion. But the critical question isn’t just about the cost of construction; it’s about the very viability of such an immense investment.

The sheer scale of building a brand-new high-speed network across such a diverse and developed urban and regional landscape presents monumental engineering and logistical challenges. From securing land and navigating complex environmental regulations to tunneling through urban centers and bridging vast distances, the price tag of $90 billion already raises eyebrows among experts and the public alike. Can such a project truly be delivered within that budget, or is it merely an initial estimate bound to balloon?

However, even if the line could be miraculously built for $90 billion, another, equally pressing question emerges: How many $31 tickets will it need to sell to make economic sense? A high-speed rail line isn’t just infrastructure; it’s a service that needs to attract sufficient ridership to justify its existence, let alone contribute to its operational costs or eventual return on investment. The $31 ticket price point will undoubtedly be competitive, but will enough commuters, business travelers, and tourists opt for the train over existing options like cars, regional trains, or even short-haul flights?

The success of this ambitious project hinges on a delicate balance between construction costs, ticket pricing, and most importantly, passenger demand. Without robust, realistic projections for ridership and a clear strategy for operational sustainability, the $90 billion high-speed rail line risks becoming an incredibly expensive white elephant. As the project moves forward, these are the fundamental questions that policymakers, planners, and taxpayers will continue to grapple with.
