MEET THE BARRAMBIN SPRINGS
Hydrogeological testing confirms Brisbane's only remaining inner-city spring is still functioning beneath Victoria Park, but would be decimated by stadiums in the park.
An independent hydrogeological assessment confirms a natural freshwater spring system still flows beneath Victoria Park Barrambin.
Today, almost all inner-city springs in Australia have been drained, buried or diverted. The Victoria Park Barrambin spring remains a rare survivor - a functioning spring-fed natural watercourse sustained by groundwater rather than pipes or runoff. The persistence of this system is extremely rare in an urban environment and gives the entire park hydrological, ecological, cultural and historical significance.
Hydrogeological assessment indicates that large-scale infrastructure over the spring or its catchment areas could permanently terminate the system.
The Science Behind Barrambin Springs
In December 2025, Brisbane-based Hydrogeologist, Ned Hamer completed an extensive hydrogeological assessment of Victoria Park Barrambin and the impacts that the proposed Olympics infrastructure may have on hydrological features of the area.
The scope involved comprehensive desktop historical research, site visits and fieldwork, including the collection of water samples for chemical analyses.
The report has been peer reviewed by Australian springs expert, Professor Rod Fensham.
Parts of a Living Spring
When we talk about a spring, we’re not just talking about the water you can see. A functioning spring depends on three connected parts -
“The broader Barrambin/Victoria Park open land forms a critical rainfall catchment area for the springs” - Ned Hamer
1. The catchment, where rain soaks into / enters the ground.
2. The aquifer, where that water is stored and filtered underground within soil and fractured rock. The water moves slowly through this rock, which is fractured like a network of tiny pathways. Water moves slowly through these cracks, sometimes taking days or weeks to travel downhill as clear flowing water.
3. The spring outlets, where water finally emerges at the surface.
Together, the open green catchment, the underlying fractured rock aquifer and the natural shape of the landscape - its steep hills and valleys - form a single living system. This confluence of physical features creates the precise conditions needed for a freshwater spring to exist. It is not just water appearing at the surface; it is the outcome of landscape, geology and rainfall working together over time. Combinations like this are rare in modern cities. Springs were once critical to human survival, which is why they hold such enduring cultural and spiritual significance around the world. If any one part of this system is disrupted, the ecology supported by the spring can no longer function properly.
At Victoria Park Barrambin, the ENTIRE northern (Herston) and southern (Spring Hill) sides of the park act as a catchment for the Barrambin Springs.
There are multiple outlets for the springs including the lake at York’s Hollow.
The ground also stores the water and releases it gradually, allowing the flow to continue even after long dry periods. This slow release is important. Rather than all rainfall moving at once, the landscape delays it - spreading water over time and reducing sudden flows.
The spring exists because the land around it absorbs water. Remove that absorption, and the spring stops.

Brisbane: A City Built on Springs
With its windy ridgelines and steep hills sweeping down to low-lying valleys, Brisbane’s dramatic topography combined with its underlying geology create the ideal conditions for groundwater springs.
Like many other cities around the world, these watercourses are at the heart of our city’s story. Long before European settlement, the area’s First Nations people centred their lives around springs – they were places of fishing, hunting wildlife, gathering and sacred ceremony. Our First Nations communities were caretakers of Brisbane’s springs for thousands of years, ensuring the benefits of these life-sustaining systems were passed down for future generations.
For the early Europeans, the area’s abundant waterholes were among the key reasons this location was chosen to build a new town. Groundwater-fed springs in what is now known as Roma Street, Spring Hill, Milton and Victoria Park formed part of a critical chain of waterholes that nourished both the new settlers and the First Nations populations, while serving as a popular recreational activity. Clear and beautiful, they were an essential tourist attraction for people visiting the city at the time.
Sadly, most of the spring systems in Brisbane’s CBD are now consigned to the history books – their catchment sources and outlets filled, paved over and long forgotten - with the exception of Barrambin. This hydrological survivor is an invaluable remnant characteristic of what was once a stunning and unique feature of the city of Brisbane. It’s a key part of the tale of how this town came to be, holding special significance in our geological, cultural and historical identity. Once destroyed, we can never get it back.
The Future of Barrambin Springs Hangs in the Balance
The State Government’s current proposal to build two major Olympic stadiums on Victoria Park – a 63,000-seat AFL venue and a 25,000-seat National Aquatic Centre), plus hard surface surrounding infrastructure (roads, bridges, retaining walls, warm up tracks, car parks, restaurants and bars) will severely jeopardise the future of Barrambin Springs. A freshwater spring is unlikely to survive if large swathes of its catchment area are smothered with concrete and roofs. While the unique hydrogeology of Victoria Park has already been heavily modified, remarkably its springs still flow. This is a historical, cultural and natural treasure for the city of Brisbane – and there is still time to protect it.
“It’s a heavily modified system, but remarkably it’s still intact. It’s survived. It was once a magnificent feature of Brisbane… but it’s diminished. We have very little left of the springs system as it is, so it’s important not just to retain what we’ve got now, but to enhance the catchment area. Taking any of the source - let alone 60-70% of the source of the flow to the springs - is unacceptable, when there are other alternatives.” - Ned Hamer

Masterplan
The Brisbane City Council (BCC) Masterplan for Victoria Park Barrambin was developed over four years (2019–2023) following extensive community consultation, with more than 80,000 people contributing ideas and feedback. The resulting plan set out a clear vision: to restore and re-wild the park and return it to the people of Brisbane as public parkland, consistent with its original purpose when it was gazetted in 1875.
Water was central to that vision. The Masterplan recognised the site’s hydrological significance and proposed initiatives including a nature water-play gully and the restoration of York’s Hollow waterholes. Below are excerpts from the Masterplan that illustrate this focus.
“There is a strong community focus on returning water to the park as it did in the earliest days of Brisbane's history. A chain of wetlands and natural waterholes follow the central park gully and highlights these water elements as the heart of the park” (Brisbane City Council Masterplan, 2023)
