When a new train station opens, commuters enjoy shorter trips and nearby homes often see a price jump. The question for buyers and developers is whether that boost can be sustained once the construction buzz fades.

When enthusiasm wanes, a so-called infrastructure hangover may cause prices to level off or fall.

Infrastructure boost and early price spikes

Nerida Conisbee, chief economist at Ray White, says the biggest lift comes before any track is laid. “When the project is confirmed, that tends to have the biggest impact because that’s when people really feel like it’s going to go ahead,” she notes.

Construction noise and road closures can pause growth temporarily, but Conisbee adds that a modest increase often returns once the work is finished.

In Queensland, the announcement that Brisbane would host the 2032 Olympic Games sparked a surge in house prices after 2021. A CBRE study attributes the continued momentum to population growth and a shortage of homes, rather than the event itself.

Investors are cautioned not to overpay amid the hype. While some suburbs near the Games venues have seen rapid appreciation, affordable entry-level options remain in areas like Logan and the Gold Coast, which already benefit from health services, jobs and transport.

That mix of factors—transport upgrades, employment hubs and demographic trends—creates a more durable value base than a single landmark project.

Long-term value and recent data

Victoria’s $21 billion Level Crossing Removal Project illustrates the pattern. Data from the Victorian Planning Authority show homes within 400 metres of a removal site rose 4 to 7 per cent, with the strongest gains recorded after the work was completed.

In Sydney, proximity to a Metro station remains a premium. Research found houses within 400 to 800 metres of a North West Metro stop sold for as much as 39 per cent more than comparable properties farther away, led by Bella Vista.

Ray White’s analysis shows that eleven suburbs along the line posted median growth of 43.75 per cent between 2019 and 2021. However, from September 2024 to September 2026 those same areas slipped by 5.07 per cent, compared with a city-wide decline of 2.40 per cent.

Conisbee points out the difficulty of separating infrastructure effects from other market forces, noting that “the biggest challenge we have is untangling what is being driven by the infrastructure, and then what’s being driven by other market factors.”

Sunny Gandhi of The Agency observes that demand for homes within walking distance of a Metro station stays strong, with a typical premium of about 10 per cent. He says agents often highlight the exact metres to the nearest station in listings.

Higher-density development around the Metro has put population pressure on local schools, and some have moved their enrolment boundaries as a result.

The New South Wales government has pledged up to $73 million in essential infrastructure funding for 44 councils, a step toward addressing capacity gaps as suburbs continue to grow.

Planning elements that complement transport

Planning experts stress that green space, walkable streets and community hubs are essential companions to new rail lines.

Zed Nasheet highlights suburbs such as Ipswich and Moreton Bay, where health facilities, jobs and transport already support steady demand.

“Smart investors follow infrastructure, transport upgrades, population growth and employment hubs,” Nasheet advises, adding that these fundamentals generate lasting value.

He also warns, “Do not overpay for it. Study the market prior to making a purchase.”

This is where architects like Phillip Rossington, a principal at BVN Architecture, come in. “When you’re involved at the start, there’s a vision created for the whole precinct,” he says. “And I think that’s the other thing people have to realise: these are long-term visions.”

Rossington says the City of Sydney’s Green Square, which rejuvenates 278 hectares of former industrial land and for which BVN designed Green Square Public School, shows how a well-planned precinct can develop harmoniously over decades. The town centre is the first to be built in Sydney in a century, and by 2041 will be home to 63,000 residents who have access to transport, shops, a library, an aquatic centre, parks and plazas.

BVN is also behind Pyrmont Place, once a quarry and council depot, that will flourish with apartments and businesses, near the light rail, ferries and an upcoming Metro station. It’s adjacent to the studio’s $830 million redesign of the iconic Sydney Fish Market for Infrastructure NSW.

Rossington sums up his outlook: “If there are trees growing, I can hear birds, and I can see people, then I think that’s it.”
