Quick answer: As a rough guide, boat insurance in Australia commonly runs from around a few hundred dollars a year for a small runabout or tinnie up to several thousand for a large cabin cruiser or yacht. Most owners of a mid-size trailer boat land somewhere in the low-to-mid hundreds per year. Your actual premium depends on the boat’s value, type, where and how you use it, and your claims history — so the only accurate number is a quote on your specific boat.
What drives the price of boat insurance
The boat’s value and type
Higher-value boats cost more to insure because there’s more to replace. A jet ski, tinnie, trailer boat, cabin cruiser and yacht all sit at different points on the scale, and performance craft usually attract higher premiums.
Agreed value vs market value
An agreed-value policy pays a set figure you lock in up front (higher premium, more certainty); a market-value policy pays what the boat is worth at the time of a claim (lower premium, less certainty). The choice noticeably changes the cost.
Where and how you use it
Your cruising area (enclosed waters vs offshore), where the boat is moored or stored, and how often you use it all feed into the premium. A boat kept in a locked garage on a trailer generally costs less to insure than one on a swing mooring.
You and your history
Your age, boating experience and claims record matter, just as they do with car cover.
Typical cost ranges (indicative only)
As a ballpark: small tinnies and jet skis often sit in the low hundreds a year; mid-size trailer boats commonly fall in the mid-hundreds; larger cabin cruisers and yachts can run into the thousands. Treat these as starting points, not quotes — two similar boats can price differently based on the factors above.
How to keep your premium down
Choosing a sensible excess, storing the boat securely, limiting your cruising area to what you actually use, bundling with other policies, and keeping a clean claims history can all pull the price down. It’s also worth reviewing your sum insured each year so you’re not over- or under-insured.
Where boat insurance fits if you’re buying
If you’re still shopping, factor insurance into your running costs alongside rego, storage and maintenance before you commit. Buying a car or trailer to tow it too? Our car buying guides and car insurance pages walk through the same thinking. For boats, caravans, jet skis and other toys, see our leisure & marine insurance page.
Boat insurance FAQs
How much is boat insurance per year in Australia?
It varies widely — from a few hundred dollars for a small boat or jet ski to several thousand for a large cruiser or yacht. The premium depends on the boat’s value, type, use and your history, so get a quote for an accurate figure.
What’s the difference between agreed value and market value?
Agreed value pays a fixed sum you set up front; market value pays what the boat is worth at claim time. Agreed value usually costs more but gives more certainty.
Does boat insurance cover the trailer?
Many policies can include the trailer and accessories, but it’s not automatic — check the product disclosure statement or ask when you get a quote.
What makes boat insurance more expensive?
Higher boat value, offshore or wide cruising areas, performance craft, a swing mooring, and a claims history all push premiums up.
Can I reduce my boat insurance premium?
Yes — a higher excess, secure storage, an accurate sum insured, a limited cruising area and a clean claims record can all help lower the cost.
