Once promised as the city’s major new green space, Brisbane’s Victoria Park is now set to lose the majority of its land to Olympic stadium construction, new research reveals.

Premier David Crisafulli in March announced plans to build a new 63,000-seat stadium at Victoria Park for the Brisbane 2032 Olympic and Paralympic Games.

He said the decision was made after a review of infrastructure options, revealing major works at the Gabba could not be completed in time, and emphasised hosting the Games at Victoria Park was the best choice for Queensland’s interests.

The new stadium will host the opening and closing ceremonies, as well as athletics events — becoming the centerpiece of the Games. Post-Games, it is expected to serve as Brisbane’s new home for cricket and AFL.

Concerns have been raised about the loss of green space, heritage values, and the adequacy of infrastructure to support the new stadium.

Critics argue the development will significantly impact the 64ha park, with some estimates suggesting at least 58 per cent of the park will be affected.

A preliminary analysis by sustainable development researcher Dr Neil Peach, commissioned by advocacy group Save Victoria Park, paints a stark picture of the impact of the Brisbane Olympics 2032.

He used government-issued visuals of the proposed stadium overlaid with Perth’s Optus Stadium — a 60,000-seat, 14-storey venue similar in size to that planned for Brisbane.

“This is an extremely hilly, challenging landscape, in a high-traffic area next to Queensland’s largest hospital — you can’t simply plonk mega venues here,” Save Victoria Park spokesperson Rosemary O’Hagan said.

She criticised the government’s promotional images as “nothing more than architectural artifice” and demanded clarity on how much public land will be lost and the true cost of the project.

“Where are the sprawling plazas, the bridges, the towering retaining walls, and the extensive amenities that will be required to cope with tens of thousands of people at a time?” O’Hagan said.

“Where are the multiple carparks and connections to roads and train stations that have been promised?”

Crisafulli stated the choice to host the games in the park was clear: “It became a choice between the embarrassment of hosting the Games at QSAC (Queensland Sport and Athletic Centre) or a new stadium at Victoria Park.

“The Games must be held at a new stadium at Victoria Park.

“Any other choice would have meant placing the government’s interests ahead of the interests of Queensland.”

Brisbane Lord Mayor Adrian Schrinner had sought to ease concerns about green space loss after Crisafulli’s announcement in March.

“The construction elements that are proposed, including the stadium and the swimming complex, will only take up a fraction of the green space,” Schrinner said.

He described the stadium as a “world-class sporting venue” and “an asset for Brisbane for decades to come”.

Meanwhile, community group Save Victoria Park has fiercely opposed the development, warning of irreversible damage to Brisbane’s green heart.

“There are — and always have been — other viable options: flat, less challenging sites not listed on Queensland’s Heritage Register,” O’Hagan said.

Despite official assurances, critics argue the government has yet to fully disclose the true scale of parkland loss or offer a clear plan for preserving Brisbane’s largest inner-city green space.
