Dennison v Brisbane City Council [2026] QSC 83

The Supreme Court of Queensland has confirmed the significant protection afforded to public authorities under s 36 of the Civil Liability Act 2003 (Qld) (CLA), dismissing a claim against Brisbane City Council (BCC) notwithstanding findings that it would otherwise have been liable in negligence.

Factual background

On 18 December 2009 at approximately 4:10-4:20am, the Plaintiff, Mr Dennison, was riding his bicycle along a footpath at Aspley when he collided with a temporary barricade erected by BCC.

The barricade consisted of orange mesh supported by metal stakes and had been installed the day prior to protect freshly poured concrete while it cured overnight. The barricade covered most of the footpath but left a narrow strip near the road for pedestrian passage. Four witches’ hats had been placed around the barricade to improve visibility, however at the time of the incident the witches’ hats were no longer in place. There was no effective lighting in the area, with the nearest streetlight being inoperative and other surrounding lights providing minimal indirect illumination. There was also no warning signs, and the barricade/stakes were not reflective, illuminated or otherwise highlighted.

The incident occurred in low light conditions shortly before dawn, with poor visibility. There were no eyewitnesses and the Plaintiff had no recollection of the incident. Consequently, the Court relied on circumstantial evidence finding that the Plaintiff was travelling at approximately 15km/h, when he attempted to pass the barricade on the right. However, due to the low light conditions and poor visibility he did not appreciate the full extent of the barrier causing him to collide with one of the metal stakes which penetrated his eye socket and cranial cavity, causing severe and catastrophic injuries, including a significant brain injury.

It was accepted that BCC owed the Plaintiff a duty of care. The key issues before the Court were whether that duty was breached and the application of s 36 of the CLA in respect to the public authority.

BCC contended that it did not breach its duty of care, submitting that the precautions it implemented were reasonable in the circumstances and that any risk was either obvious or adequately managed. While those arguments were directed to ordinary negligence principles, the ultimate question for the Court was whether BCC’s conduct met the threshold imposed by s 36 CLA.

The Court’s Decision

The Court found that, applying ordinary negligence principles, BCC would have breached its duty of care and caused the Plaintiff’s injuries. BCC failed to adequately illuminate, delineate, or warn pedestrians of the hazard created by the barricade. However, the claim ultimately failed due to the operation of s 36 of the CLA.

Section 36 and the “so unreasonable” test

The Court confirmed that s 36 applies to negligence claims generally where the conduct involves the exercise of a public authority’s statutory function. In this instance, BCC was exercising its statutory functions in relation to the control and maintenance of the footpath. Therefore, s 36 applied.

Once triggered, s 36 imposes a materially higher threshold than ordinary negligence. The Plaintiff must establish that the public authority acted in a manner that was so unreasonable that no reasonable public authority could properly consider it reasonable. This is a very high threshold. While the Court identified several deficiencies in BCC’s conduct, including the failure to replace the witches’ hats, provide adequate lighting or reflective materials, or otherwise warn of the hazard, those matters were characterised as errors of judgment within a range of reasonable responses open to BCC. Accordingly, the Plaintiff did not meet the “so unreasonable” threshold and, despite findings of breach and causation on ordinary negligence principles, BCC was not liable.

Assessment of quantum

Notwithstanding the dismissal of the claim, the Court assessed damages on a notional basis.

Total damages were assessed at approximately $675,000 and provides an insight into the applicable damages for both general damages and past care which were significant heads of damage.

Implications

Limited recovery against local councils

This decision reinforces the significant barrier to establishing liability against local councils. Even where a council creates a hazard and fails to take reasonable precautions, liability will not arise unless the elevated threshold in s 36 CLA is satisfied.

For insurers and insureds, this materially limits the prospects of recovery against public authorities. In practical terms, councils may avoid liability in circumstances where breach and causation would otherwise be established, with the effect that exposure is more likely to fall on private defendants who do not have the benefit of the same statutory protection.

In many cases, even where a council’s conduct is deficient, the inability to meet the s 36 threshold may result in private defendants bearing the whole loss.

Therefore, careful consideration should be given as to whether pursuing a council is commercially viable, or whether doing so is likely to result in unnecessary defence costs.

Identifying other Defendants & risk allocation

The decision is likely to shift focus toward non‑public authority defendants. Given the difficulty of satisfying s 36, claimants will increasingly seek to identify contractors, subcontractors and other parties involved in site setup, control, or hazard management.

For liability insurers, this creates a strategic tension. On the one hand, there is a need to proactively identify all potential contributors to the risk, rather than relying solely on the involvement of a council. On the other hand, insureds and their insurers are themselves more likely to be pursued by plaintiffs and co‑defendants for the same reason. Pursuing councils may be commercially unattractive, while private defendants are more likely to bear the residual exposure and be drawn into proceedings. Early and comprehensive investigation into all potential contributors is therefore critical, both to manage exposure and to position contribution or apportionment arguments at the outset.

Long-running litigation

The decision also highlights the long‑tail nature of catastrophic injury claims involving public authorities. The incident occurred in December 2009, with judgment delivered by the Supreme Court in 2026. For insurers, claims of this nature may persist for many years, with ultimate outcomes turning on statutory protections rather than purely factual disputes. This has implications for reserving, claims management and long‑term litigation strategy related to defence costs.

Takeaway

This decision confirms that s 36 provides a powerful shield for public authorities. While it limits recovery against councils, it correspondingly increases the likelihood that liability may be directed towards private insured defendants to ensure recovery. Insurers should therefore take a proactive and strategic approach to identifying all potential contributors and managing exposure from an early stage.
