If you own a free standing home in Thornlie, WA 6108, you're likely no stranger to the annual ritual of reviewing your home insurance premium. This article takes a close look at a real home and contents insurance quote for a four-bedroom, two-bathroom property in Thornlie — a well-established suburb in the City of Gosnells, roughly 18 kilometres south-east of the Perth CBD. We'll unpack whether the premium is competitive, how it stacks up against local and national benchmarks, and what you can do to make sure you're not paying more than you need to.

Is This Quote Fair?
The quote in question comes in at $1,471 per year (or $142/month) for combined home and contents cover, with a building sum insured of $1,041,000 and contents valued at $130,000. The building excess is $2,000 and the contents excess is $1,000.
Based on our pricing data, this quote is rated Expensive — above average for the Thornlie area.
To put that in context: the suburb average premium is $1,260/yr and the median sits at $1,207/yr, based on a sample of 45 quotes in postcode 6108. That means this particular quote is around $211 above the suburb average and $264 above the median. It also sits above the 75th percentile threshold of $1,337/yr, meaning it's more expensive than at least three-quarters of comparable quotes in the area.
That said, "expensive" doesn't automatically mean "wrong." A higher sum insured, additional features like a pool, solar panels, and ducted climate control, and the specific insurer's pricing model can all legitimately push a premium higher. The question is whether the coverage and terms justify the cost — and whether shopping around might uncover a better deal.

How Thornlie Compares
Understanding where Thornlie sits relative to broader benchmarks helps put this quote in perspective. Here's a snapshot:
| 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 |
A few things stand out here. First, Thornlie is a genuinely affordable suburb when it comes to home insurance — the suburb median of $1,207/yr is significantly below the WA state median of $1,944/yr and less than half the national median of $2,716/yr. This reflects Thornlie's relatively low-risk profile: it's not in a cyclone zone, doesn't face significant flood or bushfire exposure compared to many other parts of Australia, and has a well-established housing stock.
Interestingly, the LGA average for the City of Gosnells ($1,492/yr) is actually higher than the Thornlie suburb average, suggesting that some neighbouring suburbs within the same local government area carry slightly higher risk profiles or different property characteristics.

Property Features That Affect Your Premium
This particular property has a number of characteristics that insurers weigh carefully when calculating your premium. Here's how the key features of this home come into play:
Double Brick Construction Double brick is generally viewed favourably by insurers in Western Australia — it's durable, fire-resistant, and holds up well in storms. Homes with brick veneer or lightweight cladding can attract higher premiums, so this construction type is a genuine advantage.
Tiled Roof Terracotta or concrete tiles are a solid, long-lasting roofing material and are common in Perth's established suburbs. Tiles are generally considered a lower-risk roofing option compared to older materials like fibrous cement sheeting or corrugated iron in poor condition.
Slab Foundation A concrete slab foundation is standard for homes of this era in WA and doesn't typically raise any red flags for insurers. It's a neutral factor in most pricing models.
Built in 1983 Homes from the early 1980s are well past the warranty period but are generally solid performers — particularly in double brick construction. That said, older homes may have ageing plumbing, electrical systems, or roofing that can increase the likelihood of a claim. Some insurers price this in.
Swimming Pool A pool adds liability exposure and increases the overall replacement cost of the property. Most insurers factor this into the premium, and it's one reason this quote may sit above the suburb average.
Solar Panels Solar panels add value to the property and must be included in the building sum insured. They can also be a source of claims (storm damage, electrical faults), so they do contribute marginally to the premium.
Ducted Climate Control Ducted air conditioning is a significant fixed asset and forms part of the building's insured value. At 205 sqm, this is a reasonably sized home, and the inclusion of ducted climate control is consistent with the $1,041,000 building sum insured.
Building Sum Insured: $1,041,000 It's worth noting that the building sum insured is the single biggest driver of your premium. At $1,041,000 for a 205 sqm home, this equates to roughly $5,078 per sqm — which is on the higher end for Thornlie. It's worth reviewing whether this figure accurately reflects the cost to rebuild (not the market value), as over-insuring can mean unnecessarily higher premiums.

Tips for Homeowners in Thornlie
1. Review your building sum insured carefully The cost to rebuild your home is not the same as its market value. Use a building cost calculator or speak with a quantity surveyor to make sure your sum insured reflects actual rebuild costs — including demolition, professional fees, and compliance with current building codes. Over-insuring is a common and costly mistake.
2. Adjust your excess to find the right balance A $2,000 building excess is relatively standard, but increasing your excess can meaningfully reduce your annual premium. If you have a healthy emergency fund and are unlikely to make small claims, a higher excess could save you money over time.
3. Bundle your home and contents cover This quote already covers both building and contents, which is smart. Many insurers offer discounts for combined policies, so if you haven't already bundled, it's worth asking. Also review your contents sum of $130,000 to ensure it's accurate — both under- and over-insuring contents is common.
4. Shop around annually Insurer loyalty rarely pays off in Australia. Premiums can vary significantly between providers for identical coverage, and the home insurance market is competitive. Use a comparison tool like CoverClub to benchmark your renewal quote before you commit each year.
