Contractor Insurance: What Australian Contractors Actually Need
You're the head contractor on a $600,000 renovation. Your subcontractor's tiling work fails — the waterproofing membrane underneath wasn't properly lapped. Water leaks into the floor below. The homeowner comes after you, not the tiler. Damage claim: $35,000.
As a contractor, you carry liability for everyone working under you. Your subbies' mistakes are your problem — legally, financially, and reputationally. Insurance is what stops one subcontractor's error from sinking your entire operation.
Contractor insurance isn't one policy — it's a combination of covers designed for the specific risks contractors face on the job. Most contractors either don't have enough cover, or they're paying for policies they don't need. This guide breaks down what's required, what's recommended, what it costs in Australia, and where to get the best deal.
General information only. This page provides general information about trade insurance and does not constitute insurance or financial product advice. Cover, exclusions, licensing requirements, and premiums vary by provider, state, and work type.

What Insurance Does a Contractor Need in Australia?
Public Liability Insurance
Required for virtually every contractor. Public liability covers you if a third party — a client, a neighbour, a member of the public — is injured or their property is damaged because of your work.
For contractors, the most common claims involve subcontractor liability and project delays. These claims can easily run into tens of thousands of dollars — and that's before legal costs.
Most contractors carry $5 million to $20 million in cover. If you're subcontracting on larger sites, the head contractor will often require $10 million or $20 million minimum — check your agreements before assuming $5 million is enough.
Typical cost: $800–$2,500/year depending on your revenue, number of employees, and claims history.
Professional Indemnity Insurance
Recommended if you provide advice, design, or specifications. Professional indemnity covers you if a client claims your professional advice or recommendations caused them a financial loss.
For contractors, this matters if you've ever recommended a product, suggested a design change, or signed off on a specification. That's professional advice — and if it goes wrong, this is the policy that responds.
Typical cost: $600–$2,000/year.
Workers Compensation
Legally required if you employ anyone — including casual, part-time, or labour-hire staff. Workers comp is managed by state-based schemes (icare in NSW, WorkSafe in VIC, WorkCover in QLD) and covers your employees if they're injured at work.
As a sole trader with no employees, you don't legally need workers comp. But consider income protection instead — because you have no sick leave, no safety net, and one injury means zero income until you're back on the tools.
Contract Works
Depending on your specific general contracting work, contract works cover may be relevant. Speak with a broker who understands general contracting to determine whether this applies to your operation.
Motor Vehicle Insurance
If you drive to site — and you almost certainly do — make sure your vehicle insurance covers commercial use. A standard personal car policy may not cover an accident that happens while you're driving to or from a job. Check your PDS.
How Much Does Contractor Insurance Cost?
Here's what Australian contractors typically pay. These are real ranges based on current market rates — not theoretical figures.
| Insurance Type | Typical Annual Cost | Required? |
|---|---|---|
| Public Liability ($10M–$20M) | $800–$2,500 | Yes — virtually always |
| Professional Indemnity | $600–$2,000 | Recommended |
| Workers Compensation | Varies by state | Yes — if you employ anyone |
Total for a sole trader contractor: $1,500–$5,000/year.
Total for a contractor with 3–5 employees: $5,000–$15,000/year depending on payroll, state, and cover levels.
What affects the price? Your annual revenue, claims history, the type of general contracting work you do, your state, and the number of employees. A clean claims record is the single best way to keep premiums down.

What's covered:

- Intentional damage or work you knew was defective
Common Risks for Australian Contractors
Every trade has its own risk profile. Contractors face specific risks that make insurance non-negotiable.
Subcontractor liability. Subcontractor liability can turn a normal contracting work job into a claim for repairs, delays, and legal costs. The financial exposure is usually much bigger than the margin on the work that caused it.
Project delays. Project delays can turn a normal contracting work job into a claim for repairs, delays, and legal costs. The financial exposure is usually much bigger than the margin on the work that caused it.
Defective work claims. Defective work claims can turn a normal contracting work job into a claim for repairs, delays, and legal costs. The financial exposure is usually much bigger than the margin on the work that caused it.
Site safety incidents. Site safety incidents can turn a normal contracting work job into a claim for repairs, delays, and legal costs. The financial exposure is usually much bigger than the margin on the work that caused it.
Contract disputes. Contract disputes can turn a normal contracting work job into a claim for repairs, delays, and legal costs. The financial exposure is usually much bigger than the margin on the work that caused it.
