Guide for Tradies
Public Liability Insurance Basics for Aussie Tradies
Accidents happen on site. This extended guide explains public liability insurance basics — what it covers, typical costs in Australia, who needs it, and how to get covered fast — in plain English, with real tradie examples.
What is public liability insurance?
Public liability insurance protects your business if your work accidentally causes injury to another person or damage to their property. If a claim is made against you, your policy can cover compensation payouts and your legal defence.
Real-world examples
- A plumber bursts a pipe — the kitchen floods and the client claims for repairs.
- A carpenter drops a ladder — a passer-by is injured and seeks compensation.
- An electrician damages wiring — smoke damage triggers a property claim.
Why it matters
Without cover, you could be out of pocket for legal fees, repairs and medical costs — a bill that can shut a small trade business overnight.

Why tradies need it
Most worksites and contracts in Australia require a Certificate of Currency for public liability before you start. Beyond compliance, it’s about protecting your livelihood.
- Site requirement: Builders and commercial sites often ask for proof of cover.
- Financial protection: One mishap can cost tens of thousands.
- Professionalism: Reassures clients you take safety and responsibility seriously.
Whether you’re a sole trader, subcontractor or run a small crew, if you work around clients or the public, you’re exposed to risk.

What it covers (and excludes)
Typically covered
- Personal injury to third parties (non-employees).
- Property damage to third-party property caused by your work.
- Legal defence costs and court attendance costs.
- Compensation payouts if you’re found liable.
Not covered
- Your own injuries (that’s personal accident insurance).
- Your tools/equipment (that’s tool insurance).
- Your vehicle (covered separately under business vehicle policies).
- Employee injuries (generally a workers’ compensation matter).
Always check your specific policy wording for inclusions, exclusions and sub-limits.
Public liability insurance cost in Australia
There’s no one-price-fits-all. Insurers consider your trade, turnover, claims history, location, and the cover limit you select.
Typical monthly ranges (indicative)
- Lower-risk trades (painters, handymen): from ~$40/month
- Medium-risk trades (carpenters, tilers): ~$50–$70/month
- Higher-risk trades (plumbers, electricians): ~$70–$100+/month
These are ballpark figures — your premium may be higher or lower based on your details.
Ways to keep costs sharp
- Pick a suitable cover limit (see below).
- Consider a higher excess for a lower premium.
- Document site safety and risk controls to reduce claims.
Cover levels: $5M vs $10M vs $20M
Most tradies choose one of three public liability insurance basics cover levels:
- $5 million: Suitable for small residential jobs and direct-to-homeowner work.
- $10 million: The most common choice for mixed residential/commercial work.
- $20 million: Often required for larger commercial/government contracts.
Check your contract or site requirements — they usually specify the minimum liability limit.

Common myths (and the truth)
- “I’m a sole trader — I don’t need it.” You’re still personally liable without cover.
- “It’s too expensive.” Entry-level cover can be less than a coffee a day.
- “I only do small jobs.” Small accidents can still create big bills.
Public liability insurance basics are about protecting cash flow and your reputation — not just ticking a box.
One day public liability insurance — when it makes sense
Short-term liability cover can suit one-off events or specific short contracts where you rarely need ongoing cover. It’s usually pricier per day than an annual policy, but it can be handy if you only need proof of insurance for a limited window.
Most tradies on regular jobs find an annual policy better value and less admin.
