‘Massive’ head injury payouts looming as CTE litigation accelerates in Australia

The surge in CTE cases has rapidly moved beyond the sporting arena, spilling into the legal and insurance sectors, with insurers, sporting bodies and regulators now on high alert as the legal and financial stakes continue to escalate.

Conversations around chronic traumatic encephalopathy (CTE) have surged to new prominence in recent years, evolving from a once-niche medical concern into a rapidly intensifying public health issue demanding urgent and sustained attention.

As scientific understanding and medical research around CTE accelerates, alongside a growing wave of high-profile athlete brain injury lawsuits, a new report from Barry Nilsson warns these forces are converging to create a fast-moving and volatile risk landscape, with insurers now under pressure to closely track emerging medical findings, shifting legal trends and expanding liability exposure.

CTE is medically defined as a neurodegenerative brain condition linked to repeated head trauma, with symptoms including memory loss, confusion, impaired judgment, and progressive dementia.

In Australia, it has largely been associated with elite contact sports, including rugby league, rugby union and the AFL – placing it at the centre of an increasingly urgent debate around player safety and long-term brain health.

Scott Shelly, insurance and health principal at Barry Nilsson and co-author of the report, stressed that insurers must treat CTE as a major and rapidly evolving risk exposure, given the scale of potential compensation and the significant financial stakes involved.

“The dollar value of a head injury claim can be massive, and as awareness of CTE increases, insurers are going to face a complex and evolving risk exposure, affected by emerging medical research, developing case law and heightened regulatory scrutiny,” Shelly said.

While still an emerging area of law, Australia has already seen significant litigation involving former elite athletes and their families, including James McManus’ landmark 2017 case against the Newcastle Knights – the first of its kind in Australian sport – seeking $1 million over concussion-related injuries.

Shelly also explained that head injury cases often extend well beyond the individual affected, with families frequently bringing additional claims across related medical and psychiatric areas – ultimately driving significantly larger compensation payouts.

“This doesn’t just impact the person who’s experienced the head injuries, and a lot of what we see is that if there’s an injury or a death, the family sues for nervous shock or psychiatric injuries on the back of that, and then they get very large claims,” Shelly said.

Currently in Australia, there is no legislation directly addressing CTE; however, the report notes that legislative efforts are “underway” to redefine and regulate the assessment and compensation of traumatic brain injuries.

At this stage, CTE can only be definitively diagnosed post-mortem, but rapidly advancing and increasingly sophisticated medical research is focusing on whether biomarkers or imaging techniques may one day enable diagnosis in living individuals.

Shelly emphasised that if CTE were ever able to be diagnosed in living patients, it could significantly expand head injury litigation, fundamentally reshaping the space and potentially leading to more substantial compensation awards.

“If we were to see CTE become definitively diagnosable pre-mortem, so in a live human brain, we’d expect plaintiffs would want to expand other head injury claims, such as concussion claims by incorporating allegations of expenses and loss from CTE diagnoses, paving the way for more significant awards,” Shelly said.

However, despite growing progress in understanding CTE, the financial impact of related claims is already beginning to reshape parts of the insurance and superannuation sectors – tightening access to benefits and increasing pressure across the system.

Late last month, the AFL Players Association superannuation fund announced it would no longer pay total and permanent disability (TPD) benefits for claims relating to brain injuries after 1 May 2026.

The decision followed advice from insurer Zurich Insurance to AMP Limited, the trustee of the superannuation fund, that it could no longer sustain the level of claims being made in recent years.

While he anticipates insurers may begin reassessing their exposure to similar claims, Shelly signalled that a comprehensive rethink of existing rules and frameworks could ignite a decisive wave of proactive, risk-mitigating measures.

“I’d expect to see a review of rules and frameworks, leading to a raft of proactive measures which help to mitigate the risk of head injuries, and in turn, reduce potential future claims,” Shelly said.

But Shelly emphasised that, while risks are evolving and the landscape will continue to shift in the years ahead, the situation should not yet be regarded as cause for alarm.

“There’s no cause yet for alarm, but insurers absolutely need to stay alert and continue to pay close attention to the CTE claims landscape,” Shelly said.
