Is This Quote Fair?
The quote in question comes in at $1,175 per year (or approximately $114 per month) for combined home and contents cover. This covers a building sum insured of $843,000 and contents valued at $50,000, with a building excess of $2,000 and a contents excess of $1,000.
Our price rating for this quote is FAIR — Around Average.
That assessment holds up well under scrutiny. The suburb average for Thornlie sits at $1,260 per year, and the median is $1,207 per year, meaning this quote comes in below both of those benchmarks. It also falls comfortably within the middle band of the market — the 25th to 75th percentile range for Thornlie runs from $898 to $1,337 per year, and at $1,175, this quote lands squarely in that interquartile range.
In short: you're not getting the cheapest deal on the market, but you're not being overcharged either. For a property of this size and specification, this is a reasonable and competitive premium.

How Thornlie Compares
One of the most striking takeaways from this quote is just how favourably Thornlie compares to broader benchmarks. Check out the numbers:
| Benchmark | Average Premium |
|---|---|
| Thornlie (6108) suburb average | $1,260/yr |
| City of Gosnells (LGA) average | $1,492/yr |
| Western Australia state average | $2,144/yr |
| National average | $2,965/yr |

The gap between Thornlie and the rest of the country is largely explained by risk profile. Unlike many coastal or northern Australian regions, Thornlie is not classified as a cyclone risk area, doesn't face the flood exposure of some eastern-state suburbs, and benefits from the relatively stable climate of Perth's inland south-east. These factors keep premiums significantly lower than the national norm, particularly when compared to Queensland or Northern Territory properties where natural disaster risk dramatically inflates costs.

Property Features That Affect Your Premium
Every home is different, and insurers assess a range of property characteristics when calculating your premium. Here's how the features of this particular home are likely influencing the cost:
Double Brick Construction Double brick is widely regarded as one of the most durable and insurer-friendly wall types in Australia. It offers excellent structural integrity, strong fire resistance, and superior protection against storm damage. Homes built with double brick typically attract lower premiums than those with timber or lightweight cladding, and this property benefits accordingly.
Steel/Colorbond Roof A Colorbond steel roof is another tick in the right column. It's lightweight, resistant to corrosion, and performs well in fire-prone conditions. Compared to older terracotta or cement tile roofs, Colorbond tends to be cheaper to repair or replace, which insurers factor into their pricing.
Slab Foundation Concrete slab foundations are standard across much of Perth's post-war residential stock and are generally considered low-risk by insurers. There's no subfloor cavity to worry about, and the construction method is well-understood by builders and assessors alike.
Built in 1995 At around 30 years old, this home sits in a comfortable middle ground — past the teething issues of brand-new construction, but not yet old enough to raise concerns about ageing infrastructure or outdated building codes. Homes from the mid-1990s in WA were typically built to solid standards, particularly in double brick.
Swimming Pool The presence of a pool does add a small amount of liability exposure to a home insurance policy, and may slightly increase the premium. Pools require appropriate fencing and maintenance to meet WA safety regulations, and any damage to pool infrastructure (pumps, surrounds, plumbing) can contribute to claims.
Ducted Climate Control Ducted air conditioning is a significant fixed asset and is typically covered under building insurance. It adds to the overall replacement cost of the home, which is reflected in the higher building sum insured of $843,000.
277 sqm Building Size At 277 square metres, this is a substantial home. Larger floor areas mean higher rebuild costs, which directly influences the sum insured and, by extension, the premium. The $843,000 building sum insured appears appropriate for a home of this size and construction type in the current Perth market.

Tips for Homeowners in Thornlie
1. Review your sum insured annually Construction costs in Perth have risen significantly over the past few years. If your building sum insured hasn't been updated recently, you could be underinsured without realising it. Use a building cost calculator or speak with a local builder to sense-check your coverage figure each year.
2. Consider raising your excess to lower your premium This quote carries a $2,000 building excess and $1,000 contents excess. If you have sufficient savings to absorb a higher out-of-pocket cost in the event of a claim, opting for a higher excess can meaningfully reduce your annual premium. Just make sure the trade-off makes sense for your financial situation.
3. Maintain your pool and document its condition Pool-related claims can be costly and contested. Keep records of maintenance, ensure your fencing complies with WA's pool barrier laws, and photograph the pool area annually. This documentation can be invaluable if you ever need to make a claim.
4. Compare quotes before your renewal date Insurance loyalty doesn't always pay. Insurers frequently offer better rates to new customers than to long-standing ones. Set a reminder to shop around at least 30 days before your policy renews — you may find a materially better deal without sacrificing cover quality.
