Mandurah is one of Western Australia's most popular coastal cities, sitting about 75 kilometres south of Perth along the Peel Inlet. It attracts a broad mix of retirees, families, and sea-changers drawn to its waterways, relaxed lifestyle, and relative affordability. For owners of semi detached homes in this suburb, understanding what you should be paying for building insurance — and why — can make a real difference to your back pocket.
This article takes a close look at a recent building-only insurance quote for a 3-bedroom, 1-bathroom semi detached property in Mandurah (postcode 6210), breaking down whether the price is competitive and what factors are likely shaping the premium.

Is This Quote Fair?
The quote in question comes in at $737 per year (or approximately $69 per month) for building-only cover, with a building excess of $2,000 and a sum insured of $689,000.
Our price rating for this quote is FAIR — Around Average.
That assessment holds up well under scrutiny. The $737 annual premium sits comfortably below the suburb average of $1,173/yr and also below the suburb median of $919/yr. In fact, it falls between the 25th percentile ($555/yr) and the median for Mandurah, meaning this quote is genuinely competitive — better than roughly half of the quotes we've seen for this area, while not quite reaching the lowest tier.
For a property of this size and construction type, a "fair" rating reflects a well-priced quote that doesn't raise any red flags. It's not the cheapest possible outcome, but it represents solid value — particularly when you factor in the above-average fittings quality, the pool, and the 1981 construction year, all of which can push premiums higher with some insurers.

How Mandurah Compares
To put this quote in proper context, it helps to zoom out and look at the broader pricing landscape. Here's how the numbers stack up:
| Benchmark | Premium |
|---|---|
| This quote | $737/yr |
| Mandurah suburb average | $1,173/yr |
| Mandurah suburb median | $919/yr |
| Mandurah 25th percentile | $555/yr |
| Mandurah 75th percentile | $1,758/yr |
| Mandurah LGA average | $1,672/yr |
| WA state average | $2,144/yr |
| WA state median | $1,944/yr |
| National average | $2,965/yr |
| National median | $2,716/yr |
The spread within Mandurah itself is striking — from $555/yr at the cheaper end to $1,758/yr at the 75th percentile, based on a sample of 67 quotes. This wide range reflects the diversity of properties across the suburb: different ages, construction types, sizes, and levels of risk exposure.
What stands out most is how significantly Mandurah premiums sit below both the WA state average and the national average. At $2,144/yr, the average WA homeowner pays nearly three times what this particular quote costs. Nationally, the gap is even wider — the average Australian home insurance premium sits at $2,965/yr, more than four times this quote.
This makes Mandurah a comparatively affordable area for home insurance, even before factoring in that this specific quote is below the local median. You can explore the full Mandurah suburb insurance stats, WA state insurance data, and national home insurance benchmarks on CoverClub.

Property Features That Affect Your Premium
Several characteristics of this property are worth examining, as they directly influence what insurers charge.
Double Brick Construction
Double brick is widely regarded as one of the most resilient wall materials available in Australia. It offers excellent structural strength, fire resistance, and thermal performance. Insurers generally view double brick favourably, which can contribute to lower premiums compared to brick veneer, weatherboard, or lightweight cladding.
Tiled Roof
Terracotta or concrete tile roofs are considered a low-to-moderate risk by most insurers. They're durable, fire-resistant, and long-lasting — all positives from an underwriting perspective. Combined with the double brick walls, this property presents a solid risk profile structurally.
Slab Foundation
A concrete slab foundation is standard across much of coastal WA and is generally viewed as stable and low-risk, particularly in areas without significant subsidence or reactive soil concerns.
1981 Construction
Homes built in the early 1980s can attract slightly higher premiums than newer builds, simply because ageing systems — plumbing, electrical wiring, roofing — carry a greater probability of failure or claim. However, a well-maintained 1981 double brick home often fares better than its age might suggest.
Swimming Pool
The presence of a pool adds both value and liability to a property. Most insurers factor pool replacement costs into the sum insured calculation, and the liability risk associated with pools (particularly in households with children or visitors) can nudge premiums upward.
Above-Average Fittings Quality
Above-average fittings — think stone benchtops, quality appliances, premium fixtures — increase the cost to rebuild or repair, which flows through to a higher sum insured and, consequently, a higher premium. The $689,000 sum insured for a 105 sqm semi detached reflects this quality level.
No Cyclone Risk
Unlike parts of northern WA, Mandurah sits outside designated cyclone risk zones. This is a meaningful premium advantage — cyclone loading can add hundreds of dollars per year to premiums in affected areas.

Tips for Homeowners in Mandurah
1. Review your sum insured regularly Building costs in WA have risen significantly over recent years. A sum insured set even two or three years ago may no longer be sufficient to fully rebuild your home at today's prices. Use a building cost calculator or speak with a quantity surveyor to ensure your $689,000 coverage still reflects current rebuild costs for a double brick home with above-average fittings.
2. Consider a higher excess to reduce your premium This quote carries a $2,000 building excess. If you have a financial buffer and are unlikely to make small claims, opting for a higher excess (say, $2,500–$5,000) could meaningfully reduce your annual premium. Just ensure the excess is genuinely affordable if you ever do need to claim.
3. Shop around at renewal time Insurers don't automatically reward loyalty — in fact, many rely on inertia to retain customers at above-market rates. Given the wide spread of premiums in Mandurah (from $555 to $1,758/yr), there's clearly room to find a better deal by comparing multiple quotes each year.
4. Check your pool is properly disclosed and covered Pools must be correctly disclosed to your insurer to ensure they're included in your cover. Confirm that your policy explicitly covers pool structures, equipment, and any associated liability. Gaps in pool cover can be costly to discover at claim time.
