Is This Quote Fair?
The quote in question comes in at $1,207 per year (or $118/month) for a combined home and contents policy, covering a building sum insured of $763,000 and $100,000 worth of contents. The building excess is $2,000 and the contents excess is $1,000.
Our price rating for this quote is FAIR — Around Average, and the data backs that up. At $1,207 annually, this quote sits almost exactly on the suburb median of $1,207/yr and just slightly below the suburb average of $1,260/yr. That means roughly half of comparable Thornlie properties are paying more, and half are paying less — this homeowner is right in the middle of the pack.
That said, "average" doesn't necessarily mean "optimal." There's still a meaningful spread in what Thornlie homeowners pay. The cheapest quarter of quotes in the area come in at or below $898/yr, while the more expensive quarter are paying $1,337/yr or more. If you're currently above the median, there's a real opportunity to save by shopping around.

Property Features That Affect Your Premium
Insurance premiums aren't calculated in a vacuum. Insurers assess dozens of property-specific factors when pricing a policy. For this Thornlie home, several characteristics work in the homeowner's favour — and a couple add modest complexity.
Double Brick Construction
Built in 1983, this home features double brick external walls, which is one of the most favoured construction types among Australian insurers. Double brick offers excellent structural integrity, strong fire resistance, and durability against storm damage. Compared to weatherboard or lightweight cladding, double brick homes typically attract lower building premiums.
Tiled Roof
A tiled roof is another tick in the insurer's box. Terracotta and concrete tiles are considered durable and relatively low-risk compared to older materials like fibrous cement sheeting. They hold up well in Perth's hot, dry summers and contribute to a more competitive premium.
Slab Foundation
The concrete slab foundation is a standard and stable choice for Perth's predominantly sandy and clay soils. Slab homes are generally straightforward to assess and don't carry the subsidence concerns sometimes associated with older stumped or pier foundations.
Pool, Solar Panels & Ducted Climate Control
This property has three features that add value — and a touch of complexity — to the insurance equation. The swimming pool increases the replacement cost of the property and introduces a liability element. Solar panels represent a significant asset (often $8,000–$20,000+ to replace) and need to be explicitly covered under the building sum insured. Ducted climate control is a high-value fixed installation that also feeds into the building replacement cost.
Together, these features help justify the $763,000 building sum insured, which may seem high at first glance but is appropriate once you factor in the 205 sqm floor area, quality fixed installations, and the current cost of construction in Perth.
No Cyclone Risk
Unlike properties in northern WA, Thornlie sits outside cyclone risk zones. This is a significant premium advantage — cyclone-rated policies in regions like the Pilbara or Kimberley can cost two to three times more. Thornlie's location in Perth's south-eastern suburbs means homeowners benefit from a much more benign risk profile.

Tips for Homeowners in Thornlie
Whether you're happy with your current policy or actively shopping around, here are four practical steps to make sure you're getting the right cover at the right price.
1. Check Your Building Sum Insured Annually
Construction costs in Perth have risen sharply in recent years. The $763,000 sum insured on this quote accounts for the home's size, age, and premium fixtures — but it's worth reassessing every year. Being underinsured at claim time can leave you significantly out of pocket, even if your premium looks attractive.
2. Confirm Solar Panels Are Explicitly Covered
Many homeowners assume solar panels are automatically included in building cover — but not all policies treat them the same way. Check your Product Disclosure Statement (PDS) to confirm your panels, inverter, and associated wiring are covered for accidental damage, storm damage, and theft.
3. Review Your Pool Liability Cover
A swimming pool increases your legal liability exposure. Make sure your policy includes adequate liability cover — most comprehensive home policies include at least $10 million in legal liability, but it's worth confirming. Also check whether pool equipment (pumps, filters, heating) is included in your building sum insured.
4. Compare Quotes Before Renewal
With the suburb's 25th percentile sitting at $898/yr, there's a clear opportunity for some Thornlie homeowners to pay less. Insurers don't reward loyalty — premiums can creep up at renewal even when your risk profile hasn't changed. Shopping around every one to two years is one of the simplest ways to keep your costs in check.
