If you work as a sole trader support worker in the NDIS, you are running a business. That might not be how you think about what you do, but from a legal and financial perspective, that is exactly what you are. And running a business without the right insurance is one of the most common and costly mistakes in the disability sector.

The problem is that most sole trader support workers either assume they are covered under the provider’s policy, rely on a bare minimum public liability product they found online, or have no insurance at all. None of these positions are as safe as they sound.

The coverage assumption that gets people into trouble

When a sole trader works with an NDIS provider, there is often an assumption on both sides that someone else is holding the insurance. The provider assumes the contractor has their own cover. The contractor assumes the provider’s policy extends to them. In many cases, neither assumption is correct.

Provider policies are typically written to cover their employees. Independent contractors fall outside that definition. If something goes wrong during a support session and a participant makes a claim, a sole trader without their own cover can find themselves personally liable for legal costs and damages with no policy to respond.

What cover does a sole trader actually need?

At a minimum, sole trader support workers should be looking at three types of cover.

Public liability insurance protects you if a participant, a family member or a member of the public suffers injury or property damage as a result of your actions while providing support. If a participant falls during a session you are running, or you accidentally damage their property, public liability cover is what responds.

Professional indemnity insurance covers claims arising from your professional advice or services. In the support worker context, this matters when a participant or their family alleges that your decisions or recommendations caused them harm. Professional indemnity is not just for allied health professionals — it is relevant to anyone providing a skilled service.

Personal accident and illness cover is something most sole traders overlook entirely. If you are injured and cannot work, there is no employer paying sick leave and no workers compensation system catching you. Your income simply stops. Personal accident cover provides a replacement income while you recover.

The NDIS Commission adds another layer

Registered NDIS providers are required to ensure that the workers they engage, including contractors, meet certain screening and compliance requirements. But the insurance obligations are less clearly defined at the contractor level, which is exactly where sole traders can fall through the gap.

If a complaint is made to the NDIS Commission about a support session, the investigation process can be time-consuming, stressful and expensive. Having professional indemnity cover that includes regulatory defence costs means you are not navigating that process alone and out of pocket.

The cost of getting it wrong

A single incident without adequate cover can result in personal financial liability that far exceeds anything a sole trader has earned from their work. Legal defence costs alone, even for claims that are ultimately dismissed, can run into tens of thousands of dollars. A judgment against you without insurance to respond means those costs come directly from your personal assets.

The good news is that appropriate cover for a sole trader support worker is generally affordable, particularly when you consider the scale of the risk it manages. The challenge is knowing what to look for and making sure the product you choose is actually designed for the disability sector, not just repackaged from a generic trades or services policy.

Get it right before something goes wrong

The disability sector is built on trust. Participants and their families trust support workers with some of the most personal and vulnerable aspects of their lives. Carrying the right insurance is part of honouring that trust — it means that if something does go wrong, there is a system in place to make it right, for everyone involved.

If you are a sole trader support worker and you are not certain what cover you hold or whether it is adequate, that uncertainty is worth resolving now, before you need it.
