What Insurance Does a Mechanic Need in Australia?

Running a workshop exposes you to a specific set of risks that generic business policies were never built for. Here is a plain-English breakdown of the covers most mechanics arrange, why each one exists, and what happens when one is missing.
Quick summary
- A standard business pack does not cover the motor trade risks you face every day, including customer vehicles on your premises.
- Public liability and garage keepers liability are separate covers - most workshops that accept customer vehicles need both.
- Workers compensation is legally required the moment you employ anyone, including apprentices.
- Motor trade road risk is essential if you drive, collect, or road-test customer vehicles on public roads.
- Your risk profile and the covers you need change depending on whether you are a sole trader or employ staff.
- A broker can help you identify gaps between policies before a claim exposes them.

Why a standard business pack leaves a mechanic exposed
A motor trade business creates exposures that a standard business pack simply was not designed to respond to. You handle other people's vehicles worth tens of thousands of dollars, work with heavy lifting equipment such as two-post and four-post hoists, road-test customer cars on public roads, and store combustible materials including petrol, brake fluid, and aerosol products.
A standard business pack is built around property you own and activities that happen in a controlled location. It does not contemplate a scenario where a customer's vehicle rolls off a hoist during a brake service, or where a faulty fuel line repair causes a workshop fire that spreads to the neighbouring bay. Those events are real, they happen in Australian workshops, and the right cover handles them cleanly.
As a broker, our job is to help you build a set of covers that fits the way you actually work, so you are not paying for things that are irrelevant and not exposed on the risks that genuinely matter.
The core covers most workshops arrange
There is no single mandatory checklist, but the following covers come up repeatedly for mechanics and automotive tradespeople. Each one responds to a different type of loss, and none of them overlap cleanly with another.
- Public liability: for third-party bodily injury or property damage arising from your work or business activities
- Garage keeper's liability: for damage to customer vehicles in your care, custody or control while on the premises
- Tools and equipment: for theft, loss or damage to the gear you rely on, including diagnostic scanners, air compressors, torque wrenches, brake lathes and engine cranes
- Motor trade road risk: so you can legally road-test, collect and deliver customer vehicles on public roads
- Workers compensation: a legal requirement in most states if you employ staff, including apprentices
- Personal accident and illness: to protect your own income if you are injured or become ill and cannot work
- Commercial vehicle insurance: for the work vehicles and vans your business owns and operates
A common and costly mistake is assuming public liability also covers damage to customer cars. It does not. Damage to vehicles in your care, custody or control is handled under garage keeper's liability, a separate cover. A workshop that accepts customer vehicles for service generally needs both, and the gap between them is exactly where claims fall through.
What changes if you are a sole trader versus employing staff
A sole trader running a one-bay home workshop and a five-bay commercial shop with two apprentices and a loan car fleet have very different risk profiles. The covers that matter to each business are different in both type and scale.
Once you employ anyone, including apprentices and part-time help, workers compensation moves from optional to legally required. The scheme differs by state. In Western Australia it is administered through WorkCover WA; in New South Wales through icare; in Victoria through WorkSafe Victoria; and in Queensland through WorkCover Queensland. The Northern Territory has its own NT WorkSafe scheme. The premium is calculated on your wages bill, and failing to hold the correct cover exposes you to significant personal liability as an employer.
If you work entirely alone and your income depends on you being physically able to turn a spanner, personal accident and illness cover deserves serious consideration. It provides a benefit if an injury or illness stops you working, covering the gap that workers compensation does not fill for a sole trader.
How the type of work you do shifts the picture
A diesel and heavy-vehicle workshop handles very different exposures to a suburban general mechanic. The vehicles are heavier, the components are larger, and the consequences of a failure, such as brake fade on a laden truck, are more severe. The sum insured under a garage keeper's policy needs to reflect the vehicles you actually hold on the premises, not just the average passenger car.
Auto-electrical and mobile mechanic operations introduce their own considerations. If your work involves programming engine control units, calibrating advanced driver assistance systems, or performing diagnostic work on high-voltage hybrid and electric vehicles, it is worth confirming that the scope of your liability cover extends to those activities explicitly, because some earlier-generation motor trade policies were written before these services became common.
Marine mechanics and boat repairers operate under different marine trade conditions. Vehicles on or near water, slipways and trailers all create a risk environment that differs from a land-based workshop, and the cover needs to reflect it.
Getting the structure right before something goes wrong
The value in working with a broker is not just in finding a policy, it is in making sure the covers sit together without gaps. A tools policy, a liability policy, and a road risk policy each do a specific job, and the boundaries between them are exactly where claims become complicated if they have not been thought through in advance.
Consider a scenario where a technician drives a customer's vehicle out of the workshop for a road test, clips a kerb and damages the wheel. Is that a road risk claim or a garage keeper's claim? The answer depends on the exact policy wording, and it matters. A broker can walk you through how each cover is intended to respond and how they sit alongside each other.
We take the time to understand how your business runs before making any recommendation. If a cover is not relevant to what you do, we will say so rather than padding out a package. Speak to a broker to work through the right structure for your workshop.
Frequently Asked Questions
Workers compensation is a legal requirement in most Australian states and territories once you employ staff, including apprentices. The administering body varies by state: WorkCover WA, icare NSW, WorkSafe Victoria, WorkCover Queensland, and NT WorkSafe. Other covers such as public liability are not usually compulsory by law, but are frequently required under lease agreements, trade licences, and contracts with dealerships or fleet operators.
