If you own a free standing home in Illawong, NSW 2234, you're in one of Sydney's most appealing southern suburbs — a leafy, family-friendly pocket of the Sutherland Shire nestled between the Georges River and the Royal National Park. But with desirable real estate comes meaningful insurance responsibility. This article breaks down a recent home and contents insurance quote for a five-bedroom property in the area, compares it against suburb, state, and national benchmarks, and offers practical guidance for homeowners looking to make sure they're getting a fair deal.

Is This Quote Fair?
The quote in question sits at $4,586 per year (or $439 per month), covering a building sum insured of $1,577,000 and $150,000 in contents — with a $5,000 excess on both building and contents claims.
Based on our analysis, this quote is rated Expensive (Above Average). Here's why that matters.
Looking at Illawong's local insurance data, the suburb average premium is $3,723/yr and the median sits at $3,579/yr. The quote at $4,586 lands well above both figures — and even above the 75th percentile for the suburb, which is $4,313/yr. In plain terms, this homeowner is paying more than roughly three-quarters of comparable properties in the same postcode.
That said, context is everything. A building sum insured of $1,577,000 is substantial, and a 315 sqm double brick home with a pool, solar panels, and ducted climate control is far from a bare-bones property. Premium pricing reflects replacement cost and feature complexity, so some elevation above the median is expected. The key question is whether the gap is proportionate — and at nearly $1,000 above the suburb average, it's worth shopping around.

How Illawong Compares
To put this quote in proper perspective, here's how Illawong stacks up against broader benchmarks:
| Benchmark | Average Premium | Median Premium |
|---|---|---|
| Illawong (NSW 2234) | $3,723/yr | $3,579/yr |
| New South Wales | $9,528/yr | $3,770/yr |
| National | $5,347/yr | $2,764/yr |
| Sutherland LGA | $23,423/yr | — |
A few things stand out here. The NSW state average of $9,528/yr looks alarming at first glance, but the median of $3,770/yr tells a more grounded story — that figure is skewed upward by high-risk and high-value properties across the state, including flood and bushfire-prone regions. Illawong's median of $3,579/yr is actually slightly below the NSW median, suggesting it's a relatively insurable suburb by state standards.
The national average of $5,347/yr with a median of $2,764/yr reflects the enormous diversity of risk across Australia — from cyclone-prone Queensland to bushfire-affected regional areas. Illawong compares favourably on a national scale.
The Sutherland LGA average of $23,423/yr is an outlier worth flagging. This is almost certainly pulled upward by a small number of very high-value or high-risk properties within the broader local government area. It's not a useful benchmark for a typical Illawong home, but it does underscore how dramatically property characteristics and location risk can influence premiums within a single LGA.
Based on 63 quotes sampled in the suburb, Illawong has a reasonably robust data set — giving us good confidence in these local figures.

Property Features That Affect Your Premium
This particular property has several characteristics that directly influence its insurance cost, both positively and negatively.
Double brick construction is generally viewed favourably by insurers. It offers strong structural integrity, good fire resistance, and durability — all of which reduce the likelihood of a total loss. Compared to lightweight timber-framed homes, double brick often attracts lower building premiums.
Tiled roof is another tick in the right column. Terracotta and concrete tiles are among the more insurer-friendly roofing materials, offering longevity and resistance to ember attack — relevant even in areas not formally classified as high bushfire risk.
Slab foundation is standard for many NSW homes of this era and presents no particular concerns for insurers in a suburb like Illawong, where soil movement risk is moderate.
Timber and laminate flooring can add complexity to contents and building claims, as these materials can be costly to replace and are susceptible to water damage. It's worth confirming your policy covers floor coverings adequately.
The swimming pool adds to both the replacement value of the property and the liability exposure — insurers factor in the cost of pool fencing, pumps, filtration systems, and the pool shell itself. This is a meaningful contributor to the building sum insured.
Solar panels are increasingly common but still add complexity. A quality solar system can represent $10,000–$30,000 or more in replacement cost, and not all policies cover them under the building section by default. Always confirm your solar panels are explicitly included.
Ducted climate control is another high-value fixed asset that contributes to the building sum insured. Systems of this type can cost $15,000–$30,000 to replace, and their inclusion in the rebuild estimate is entirely appropriate.
The property was built in 1985, which means it's approaching 40 years old. Older homes can attract slightly higher premiums due to ageing wiring, plumbing, and roofing — though double brick construction tends to age more gracefully than other materials.

Tips for Homeowners in Illawong
1. Review your sum insured carefully A building sum insured of $1,577,000 for a 315 sqm home works out to roughly $5,006 per square metre. This is on the higher end but may be justified given the quality of construction and the cost of inclusions like the pool, solar, and ducted systems. Use a quantity surveyor or an online rebuild calculator to validate this figure — being over-insured means you're paying more premium than necessary, while being under-insured can leave you badly exposed at claim time.
2. Compare quotes from multiple insurers With this quote sitting above the 75th percentile for the suburb, there's a reasonable chance a comparable level of cover is available at a lower price. Use CoverClub to compare quotes and see what other insurers are offering for your specific property.
3. Confirm your solar panels and pool are properly covered These are two areas where policy wording varies significantly between insurers. Ask specifically whether solar panels are covered under the building section, and whether pool equipment (pumps, filters, heating) is included. Gaps here can be costly.
4. Consider your excess strategically Both building and contents excesses are set at $5,000. A higher excess typically reduces your annual premium — but $5,000 is already a meaningful out-of-pocket cost in the event of a claim. If you haven't already, ask your insurer what the premium difference would be at a $2,500 or $3,000 excess, and weigh up whether the saving is worth the trade-off.
