If you own a four-bedroom free standing home in Thornlie, WA 6108, you've probably wondered whether you're paying a fair price for home and contents insurance — or whether there's a better deal out there. Thornlie is a well-established suburb in the City of Gosnells, roughly 18 kilometres south-east of Perth's CBD, known for its solid brick homes built predominantly from the 1970s through to the 1990s. With property values rising and the cost of living squeezing household budgets, understanding exactly what drives your insurance premium has never been more important.
This article breaks down a real home and contents insurance quote for a 214 sqm, double brick home in Thornlie, compares it against local, state and national benchmarks, and offers practical tips to help you get better value on your cover.

Is This Quote Fair?
The quote in question comes in at $2,302 per year (or $221 per month) for combined home and contents insurance, with a building sum insured of $683,000 and contents valued at $213,000. Both the building and contents excess are set at $1,000.
Our price rating for this quote is Expensive — Above Average.
To put that in context: the suburb average for Thornlie sits at just $1,644 per year, with a median of $1,618. That means this quote is running approximately 40% above the suburb average — a meaningful gap that's worth investigating before simply renewing.
That said, it's important to look beyond headline figures. This property carries a relatively high building sum insured ($683,000) and a substantial contents value ($213,000), both of which will push the premium upward compared to properties with lower coverage levels. A pool on the property also adds a layer of liability risk that insurers factor into their pricing. So while the "expensive" rating is accurate relative to the suburb, some of that cost reflects the breadth of cover being sought.

How Thornlie Compares
Understanding where Thornlie sits in the broader insurance landscape helps frame whether a quote represents genuine value.
| Benchmark | Annual Premium |
|---|---|
| This Quote | $2,302 |
| Thornlie Suburb Average | $1,644 |
| Thornlie Suburb Median | $1,618 |

Based on 117 quotes collected for the Thornlie suburb.
A few things stand out here. First, this quote sits above the suburb's 75th percentile of $2,152, meaning it's more expensive than at least three-quarters of comparable quotes in the area. That's a clear signal to shop around.
Second — and this is worth appreciating — the quote is actually below both the WA state average ($2,811) and the national average ($5,347). Homeowners in other parts of Australia, particularly in Queensland and Northern Australia where cyclone and flood risk is elevated, routinely pay far more. Thornlie's location in metropolitan Perth, outside any cyclone risk zone, is a genuine advantage when it comes to insurance pricing.
The LGA of Gosnells records an average of just $1,427, which is notably lower than the suburb figure — suggesting that some pockets of the LGA benefit from even more competitive pricing. It's worth keeping this in mind when comparing quotes.

Property Features That Affect Your Premium
Several characteristics of this particular property have a direct bearing on what insurers charge.
Double Brick Construction Double brick is widely regarded as one of the most durable and insurer-friendly building materials in Australia. It offers strong resistance to fire, wind and impact damage, which typically translates to lower rebuild risk in insurers' eyes. This is a genuine plus for the property.
Tiled Roof Terracotta or concrete tiles are considered a mid-range risk for insurers — more durable than Colorbond in some respects, but potentially more expensive to repair if damaged by hail or falling debris. Overall, tiles are a standard and generally well-regarded roofing material.
Slab Foundation A concrete slab foundation is common in Perth homes of this era and is generally viewed neutrally by insurers. It doesn't carry the subsidence concerns sometimes associated with older stumped or timber-framed foundations.
Timber and Laminate Flooring Flooring type can influence contents and building claims, particularly for water damage. Timber and laminate floors can be costly to replace if a pipe bursts or an appliance leaks, so it's worth ensuring your sum insured adequately reflects replacement costs.
Swimming Pool A pool increases the insurable risk on a property — both in terms of potential liability (especially relevant if children visit the property) and the cost of the pool structure itself. Many insurers include pool cover under the building policy, but it's worth confirming exactly what's covered and whether the pool fence compliance is up to date, as this can affect claims.
Ducted Climate Control Ducted air conditioning is a significant fixed asset and adds to the overall building replacement value. At standard fittings quality, this is already factored into the building sum insured, but it's worth reviewing whether the $683,000 figure genuinely reflects today's rebuild costs — construction prices have risen sharply in recent years.
1984 Construction Homes built in the 1980s are generally well-constructed, particularly in double brick, but may have older electrical wiring, plumbing or roofing components that could affect claims. Some insurers apply age-related loadings to older properties.

Tips for Homeowners in Thornlie
1. Review Your Sum Insured Annually With construction costs having increased significantly since COVID, many homeowners find their building sum insured is either too low (underinsurance risk) or, in some cases, higher than necessary. Use an independent building cost calculator or speak with a quantity surveyor to validate your $683,000 figure against current rebuild costs in Perth.
2. Shop Around — Especially Above the 75th Percentile Since this quote sits above three-quarters of comparable quotes in Thornlie, there's a strong case for comparing at least three to four insurers before renewing. Premiums for the same property can vary by hundreds of dollars depending on the insurer's risk appetite and current book composition.
3. Check Your Pool Compliance Insurers may ask about pool fencing compliance, and an uncompliant fence could complicate a liability claim. Ensuring your pool barrier meets WA's Building Regulations is both a legal requirement and good insurance hygiene.
4. Consider Your Excess Level Both excesses on this policy sit at $1,000. Opting for a higher voluntary excess — say, $1,500 or $2,000 — can meaningfully reduce your annual premium. If you have an emergency fund and are unlikely to make small claims, this trade-off often makes financial sense.
