Thornlie is a well-established suburb in Perth's south-eastern corridor, sitting within the City of Gosnells. Known for its family-friendly streets and solid brick homes built throughout the 1970s and 80s, it's exactly the kind of suburb where getting your home insurance right really matters. This article breaks down a real home and contents insurance quote for a four-bedroom, double brick free standing home in Thornlie — and puts the numbers in context so you can make a more informed decision.

Is This Quote Fair?
The annual premium for this property comes in at $1,104 per year (or $105 per month), covering both building ($500,000 sum insured) and contents ($100,000). Based on comparison data from Thornlie's local insurance market, this quote has been rated Fair — Around Average.
What does that actually mean? The suburb average premium sits at $1,260 per year, and the median is $1,207. At $1,104, this quote is tracking comfortably below both the suburb average and median — roughly 12% under the average and about 9% under the median. That's a meaningful saving without being in the cheapest quartile (the 25th percentile sits at $898/yr), which would typically indicate a stripped-back policy.
The "Fair" rating reflects that while this isn't the cheapest quote available in Thornlie, it's competitive relative to the local market and likely reflects a policy with reasonable coverage breadth. For a property of this size and age — with a pool, solar panels, and ducted climate control — landing below the suburb average is a solid outcome.

How Thornlie Compares to the Rest of Australia
One of the most striking takeaways from this data is just how much cheaper insuring a home in Thornlie is compared to broader benchmarks.
| Benchmark | Average Premium | Median Premium |
|---|---|---|
| Thornlie (6108) | $1,260/yr | $1,207/yr |
| LGA – City of Gosnells | $1,492/yr | — |
| Western Australia | $2,144/yr | $1,944/yr |
| National | $2,965/yr | $2,716/yr |
Compared to the WA state average of $2,144, Thornlie homeowners are paying roughly 48% less on average. Against the national average of $2,965, the difference is even more pronounced — Thornlie sits at less than half the national benchmark.
This reflects several favourable risk factors in the area: Thornlie is not in a cyclone risk zone, it's not a bushfire-prone coastal fringe suburb, and the predominantly brick construction of homes in the area is viewed favourably by insurers. The relatively flat terrain and established urban infrastructure also reduce flood and storm risk compared to many other parts of Australia.
The quote analysed here — at $1,104 — sits $156 below the Thornlie suburb average and a substantial $1,040 below the WA state average. For a four-bedroom home with a pool and solar panels, that's genuinely competitive.

Property Features That Affect Your Premium
Several characteristics of this property have a direct influence on what insurers charge. Here's how they stack up:
Double Brick Construction Double brick is one of the most insurer-friendly wall types in Australia. It's fire resistant, structurally robust, and typically cheaper to insure than timber or clad homes. For a 1978-built home in Perth's south-east, double brick is the norm — and it works in the homeowner's favour at renewal time.
Tiled Roof Terracotta or concrete tiles are considered a durable, low-risk roofing material by most insurers. They hold up well in storms and are less susceptible to fire than Colorbond or older corrugated iron, contributing to a more favourable premium.
Slab Foundation A concrete slab foundation is standard for homes of this era in WA and presents minimal additional risk. Unlike homes on stumps or piers, there's less concern about subsidence or pest damage to structural supports.
Swimming Pool A pool adds value to the property and increases the cost to rebuild or repair — which is factored into the building sum insured. It also introduces a small liability element. Expect the pool to contribute modestly to the overall premium.
Solar Panels Solar systems are now specifically covered under most home building policies, but they do add to the replacement cost of the home. A system installed on a tiled roof also carries some risk of tile damage during installation or maintenance. The $500,000 building sum insured should be verified to include the full replacement value of the solar system.
Ducted Climate Control Ducted air conditioning is a significant fixed asset and forms part of the building sum insured. It's worth confirming your policy explicitly covers ducted systems for both mechanical breakdown (if included) and physical damage.
Building Size: 130 sqm At 130 sqm, this is a modest footprint for a four-bedroom home. The $500,000 building sum insured equates to roughly $3,846 per sqm — which is on the higher end for Perth but may reflect the cost of the pool, solar, and climate control infrastructure, as well as current construction cost inflation.

Tips for Homeowners in Thornlie
1. Review Your Building Sum Insured Annually Construction costs in Perth have risen sharply over the past few years. A sum insured set two or three years ago may no longer reflect the true cost to rebuild your home. Use a building cost calculator or speak with a quantity surveyor to sense-check your coverage, especially with a pool and solar system in the mix.
2. Check What's Covered for Your Pool and Solar Not all policies treat pools and solar panels the same way. Some insurers cover solar panels as part of the building, others require a specific endorsement. Confirm that your policy covers the panels for storm damage, hail, and accidental breakage — not just fire.
3. Consider Your Excess Levels Strategically This policy carries a $2,000 building excess and $1,000 contents excess. Higher excesses generally reduce your premium, but make sure you can comfortably cover those amounts out of pocket in the event of a claim. If cash flow is a consideration, a lower excess (even at a slightly higher premium) can be worth it.
4. Compare at Renewal — Not Just at Inception The insurance market in Thornlie has 45 quotes in our dataset, with a spread from $898 to over $1,337 per year. That's a wide range for the same suburb. Don't assume your current insurer will remain competitive — comparing quotes each year is one of the simplest ways to avoid paying more than you need to.
