If you have looked into insurance for your NDIS business, you have almost certainly encountered two terms: public liability and professional indemnity. Most providers end up with one or the other, or both, without fully understanding what each one does or why both might be necessary.

Getting this wrong is not just a gap in your paperwork. It is a gap in your actual protection.

What public liability covers

Public liability insurance responds when a third party — a participant, a family member, a member of the public — suffers injury or property damage as a result of your business activities. If a participant is injured during a support session, if someone trips over equipment at your premises, or if a support worker accidentally damages a participant’s home, public liability is the cover that responds.

It is concerned with physical outcomes. Something happened, someone was harmed or their property was damaged, and your business activities were involved. Public liability covers the legal costs of defending a claim and any damages awarded.

For NDIS providers, public liability is non-negotiable. The nature of disability support means your staff are regularly in participants’ homes, supporting people with complex physical needs, and operating in environments where incidents can and do occur.

What professional indemnity covers

Professional indemnity insurance operates in a different space. It responds to claims arising from your professional advice, recommendations, or services, specifically when a client alleges that something you did or said in your professional capacity caused them financial loss or harm.

In the NDIS context, this is broader than it might initially sound. A support coordinator who recommends a particular service arrangement that subsequently fails. A behaviour support practitioner whose plan is alleged to have caused distress. An organisation whose intake assessment is claimed to have missed a critical risk factor. These are all professional indemnity scenarios, not public liability scenarios.

The distinction matters because a claim that arises from your professional judgement will not be covered by your public liability policy. The two covers respond to fundamentally different types of claims.

Where NDIS providers get confused

The confusion usually comes from the fact that in practice, a single incident can involve both types of claim. A participant is injured during a support session (potentially a public liability claim), and the family also alleges that the support plan was negligently designed and contributed to the conditions that led to the injury (potentially a professional indemnity claim). If you only hold one type of cover, part of that claim is responding and part of it is not.

This is particularly relevant for NDIS providers because the sector blurs the line between physical support and professional service. Support workers are not just providing manual assistance — they are making decisions, following plans, and exercising professional judgement as part of their role.

Which one do you need?

The honest answer for most NDIS providers is both. The specific type of work you do affects how urgently each one matters.

If you are a sole trader providing basic social support or domestic assistance with no advisory component, public liability is your primary need. But if you are a registered provider, a support coordinator, an allied health professional working under an NDIS framework, or an organisation delivering complex supports, professional indemnity is equally important.

The risk of holding only public liability is that any claim involving your professional judgement, your recommendations, or the design of your services falls outside your cover entirely. In a sector as regulated and scrutinised as the NDIS, that is a significant exposure.

Making sure the cover fits the work

Both public liability and professional indemnity policies vary significantly in their terms, limits and exclusions. A generic professional indemnity policy written for a management consultant is not the same as one written for an NDIS provider. The specific risks of the disability sector — participant vulnerability, NDIS Commission oversight, the complexity of behaviour support and high intensity services — need to be reflected in the policy terms, not just the product category.

When you are reviewing your insurance, the question is not just whether you have public liability and professional indemnity. It is whether the specific policies you hold are actually fit for the work you do.
