Thornlie is a well-established suburb in Perth's south-eastern corridor, sitting within the City of Gosnells and home to a mix of solid brick family homes built across several decades. If you own a free-standing home here, understanding what you should be paying for home and contents insurance — and why — can save you hundreds of dollars a year. This article breaks down a real quote for a 4-bedroom, 2-bathroom property in Thornlie (postcode 6108) and puts the numbers into context.

Is This Quote Fair?
The quote in question comes in at $2,118 per year (or $203/month) for combined home and contents cover, with a building sum insured of $638,000 and contents valued at $50,000. Both the building and contents excess sit at $500.
Our pricing engine has rated this quote as Fair — Around Average, and the data backs that up. At $2,118 annually, this premium sits just above the suburb average of $1,644 and the suburb median of $1,618, but comfortably within the 75th percentile of $2,152. In other words, roughly three-quarters of comparable quotes in Thornlie come in at a similar price or lower — but only just.
The "fair" rating reflects that this isn't a bargain, but it's also not an outlier. For a 214 sqm home with ducted climate control, solar panels, and a building sum insured of $638,000, the premium is broadly in line with what the market is charging for this type of property in this area.
That said, "fair" doesn't mean you can't do better. Even a modest saving of $200–$300 per year adds up to real money over the life of your mortgage.

How Thornlie Compares
One of the most useful things you can do when assessing any insurance quote is to zoom out and look at the broader picture. Here's how this premium stacks up across different geographic levels:
| Benchmark | Average Premium | Median Premium |
|---|---|---|
| Thornlie (6108) | $1,644/yr | $1,618/yr |
| LGA (Gosnells) | $1,427/yr | — |
| Western Australia | $2,811/yr | $2,127/yr |
| National | $5,347/yr | $2,764/yr |
A few things stand out here. First, Thornlie homeowners are paying significantly less than the WA state average, and dramatically less than the national average — a reflection of the suburb's relatively low risk profile. There's no cyclone exposure, no significant flood history compared to higher-risk postcodes, and the area's predominantly brick construction tends to attract more competitive premiums.
Second, the LGA of Gosnells actually posts a lower average ($1,427/yr) than the Thornlie suburb average ($1,644/yr), which may reflect a mix of property types and sizes across the broader council area.
The quote of $2,118 sits above both the suburb and LGA averages, but below the WA state average — which is a reasonable position for a larger-than-average home with a high building sum insured.

Property Features That Affect Your Premium
Every property tells its own story when it comes to insurance pricing. Here are the key features of this home and how they influence the quote:
Double Brick Construction
Double brick is one of the most insurer-friendly wall types in Australia. It's durable, fire-resistant, and holds up well in storms. Insurers generally view it favourably, and it often translates to lower premiums compared to weatherboard or clad homes of a similar size.
Steel/Colorbond Roof
Colorbond roofing is extremely common in Perth and is well-regarded by insurers for its durability and resistance to corrosion and fire. It's a tick in the "lower risk" column and helps keep premiums competitive.
Slab Foundation
A concrete slab foundation is standard for homes of this era in WA and presents minimal additional risk from an insurance perspective. It's structurally stable and doesn't carry the subsidence concerns that can affect older pier-and-beam foundations.
Solar Panels
Solar panels are increasingly common on Perth homes, and most insurers now include them as part of building cover — but it's worth confirming this with your insurer. The panels themselves add some replacement value to the building, which may contribute marginally to the premium.
Ducted Climate Control
Ducted air conditioning systems are a significant fixed asset in any home. They add to the overall replacement cost of the building and are factored into the building sum insured. At $638,000, this home's sum insured is on the higher end for the suburb, which partly explains why the premium sits above the local average.
1995 Construction
Homes built in the mid-1990s are generally well-regarded by insurers — old enough to be established and structurally proven, but not so old as to carry the maintenance risks of pre-1980s construction. Wiring, plumbing, and roofing from this era are typically in reasonable condition, which helps keep premiums in check.

Tips for Homeowners in Thornlie
Whether you're reviewing your current policy or shopping for the first time, here are four practical steps to make sure you're getting value from your home insurance:
1. Review your building sum insured regularly Construction costs in Perth have risen sharply in recent years. A sum insured that was accurate three years ago may now leave you underinsured. Use a building replacement cost calculator — not the market value of your home — to set the right figure. $638,000 for a 214 sqm double brick home in Thornlie is worth double-checking against current builder rates.
2. Compare quotes before your renewal date Most insurers automatically renew your policy, often with a premium increase. Set a reminder two to three weeks before your renewal date to compare quotes on CoverClub and see whether a competing offer stacks up better.
3. Consider your excess carefully Both excesses here are set at $500, which is a common default. Opting for a higher excess (say, $1,000) can reduce your annual premium meaningfully — but make sure you can comfortably cover that amount out of pocket if you need to make a claim.
4. Check what's included for your solar panels Not all policies treat solar panels the same way. Some include them automatically under building cover; others require a specific endorsement. Given the cost of a full solar system, it's worth a quick call to your insurer to confirm you're fully covered.
