Brisbane’s Hidden History: How 2011 Floods Unearthed Thousands of Colonial Artefacts in Race Against Time

In a purpose-built warehouse at the Queensland Museum in Hendra, young archaeology students are hunched over fragments of Brisbane’s past that were violently dislodged by the 2011 floods, piecing together a puzzle that began with disaster.

Emily Totivan, 19, wears blue plastic gloves as she carefully assembles ceramic shards in the Queensland Museum’s Collections and Research Centre. The fragments once formed dinner plates used by Brisbane residents more than 150 years ago, decorated with intricate blue and white Chinese-inspired patterns that were wildly popular in colonial Queensland.

These aren’t treasures carefully excavated from a planned archaeological dig. They’re survivors of an extraordinary rescue mission that began during Brisbane’s catastrophic 2011 floods, when a burst water main on William Street sent tens of thousands of historical artefacts cascading past the convict-built Commissariat Store, one of Queensland’s oldest buildings.

As emergency crews worked to restore access to one of the city’s major streets, the University of Queensland Archaeological Services Unit faced a race against time to salvage what they could before the road reopened. The result is what’s now known as the William Street assemblage, a collection of everyday objects from the 1870s to 1890s that offers an intimate glimpse into early Brisbane life during its transformation from penal settlement to thriving river port capital.

Among the recovered items are clay pipes and rum bottles, ceramic dolls and a bone toothbrush, and even a chamberpot. These objects tell stories of the ordinary people who built the city—fragments of lives that might otherwise have been lost forever beneath the bitumen.

For fellow student Elisha Kilderry, the experience of handling these artefacts is surreal. She’s piecing together a geometric viridian green chamberpot once used by people who lived on the same streets she walks today.

Initially, Kilderry imagined her archaeology career would take her to Europe or remote Indigenous cultural heritage sites. Instead, she finds herself engrossed in the quotidian details of colonial Brisbane life.

The timing of this cataloguing work couldn’t be more relevant for Brisbane. As the city prepares for the 2032 Olympics, Queensland Museum archaeology curator Nick Hadnutt says the city is on the brink of a boom in salvage archaeology. Massive infrastructure projects—including the proposed 63,000-seat stadium at Victoria Park, a site heritage-listed for its rich Indigenous, colonial and multicultural history—will churn up vast amounts of soil, potentially revealing countless more fragments of Brisbane’s past.

University of Queensland lecturer Dr Caitlin D’Gluyas organised the first hands-on cataloguing experience for students this January, with many more applicants than available positions. She says the collaborative nature of archaeology creates unique bonds between participants.

While the William Street objects hold limited scientific value due to their violent dislodgement—the archaeological context that usually provides crucial information was destroyed by the flood—they were acquired by the museum for more emotive reasons.

One particularly poignant artefact demonstrates this tangible connection to the past: a small ink bottle from the heritage-listed government printing house. It still contains a dash of ink—an exquisite midnight shade—last used over a century ago, perhaps to print an act of parliament. When students used a paper towel to clean it, the ancient ink still stained the cloth.

For student John Duckett, 21, from Rockhampton, who previously volunteered on a Bronze Age brewery dig in Norfolk, England, there’s something irreplaceable about this physical connection to history.

As Brisbane transforms for its Olympic future, these students are working against the clock to preserve fragments of its colonial past. With major infrastructure projects looming, the question isn’t whether more historical treasures will be unearthed—it’s whether we’ll be ready to catch them when they surface.

The lesson from William Street is clear: Brisbane’s history lies waiting beneath our feet, vulnerable to the next flood, the next burst pipe, or the next stadium excavation. In Hendra, a dedicated team is ensuring that when those fragments emerge, they won’t be lost to time.

Albion Schoolboy’s 1958 Fossil Find Confirmed as Australia’s Oldest Dinosaur Footprint

A dinosaur footprint collected by a schoolboy at a quarry in Albion in 1958 has been confirmed as Australia’s oldest known dinosaur trace fossil, reshaping understanding of the country’s prehistoric timeline and securing a lasting scientific legacy for the suburb.



The Find at Albion

In 1958, Professor Bruce Runnegar, then a Brisbane Grammar School student, visited Petrie’s Quarry at Albion with school friends and removed a slab of fine-grained shale bearing a clear footprint impression. Born in Brisbane, Professor Runnegar was already familiar with the quarry through earlier fossil-hunting visits.

At the time, the markings were suspected to be dinosaur tracks, but no formal study followed. No photographs or measurements were taken, and the slab was removed from a newly exposed track surface without documentation. In subsequent decades, residential development rendered the original quarry site permanently inaccessible, eliminating any opportunity to revisit the footprint in situ.

Albion’s Geological Setting

Long before Albion became a residential inner-north suburb, the area was defined by prominent sandstone bluffs and extensive quarrying. Petrie’s Quarry was worked from the nineteenth century and was known among geologists for its Triassic rock layers and fossilised plant material.

The quarry cut through the Aspley Formation, a Late Triassic geological unit dating to around 230 million years ago. Sandstone extracted from the site was later used in construction across Brisbane, embedding material from Albion’s deep geological past into the city’s built environment. By the mid-twentieth century, the quarry remained accessible to students and amateur collectors, even as urban development expanded around it.

From Schoolboy to Scientist

The fossil remained in Professor Runnegar’s care for decades. He went on to study at The University of Queensland, before building an academic career that included teaching and research positions at the University of New England in Armidale and later at the University of California, Los Angeles. Throughout that time, the Albion footprint travelled internationally as part of his teaching collection.

Now 85, Professor Runnegar is a UQ Honorary Professor and a co-author of the research that formally documented the fossil. The continuity between the schoolboy who collected the footprint and the academic who later helped describe it underpins the specimen’s eventual recognition.

Formal Scientific Recognition

The footprint was formally examined decades later by Dr Anthony Romilio, a palaeontologist with the Dinosaur Lab at The University of Queensland. Using modern digital documentation and analytical techniques, the specimen was studied in detail for the first time.

The analysis confirmed the footprint dates to the Carnian stage of the Late Triassic period, approximately 230 million years ago, and originates from the Aspley Formation. This places the track significantly earlier than any previously confirmed dinosaur evidence in Australia, establishing it as the earliest known dinosaur trace fossil in the country.

The footprint measures 18.5 centimetres and preserves the impression of a small, two-legged dinosaur consistent with an early sauropodomorph, a primitive relative of later long-necked dinosaurs. Modelling indicates the animal stood about 75 to 80 centimetres at the hip, weighed roughly 140 kilograms, and was capable of relatively fast movement for its size.

Albion’s Enduring Legacy

The research established the footprint as the first confirmed dinosaur fossil found within an Australian capital city. With Petrie’s Quarry long redeveloped, the specimen represents the only surviving dinosaur evidence from that Albion locality.

The fossil is now housed at the Queensland Museum, where it is available for ongoing research. The formal scientific description was published in Alcheringa: An Australasian Journal of Palaeontology in February 2026.



What began as an undocumented schoolboy discovery at an Albion quarry has since become a foundational reference point in Australia’s dinosaur history, linking a small inner-Brisbane suburb to one of the earliest chapters of life on the continent.
