Lake Illawarra is a relaxed lakeside suburb on the NSW South Coast, sitting within the Wollongong Local Government Area about 80 kilometres south of Sydney. It's a popular spot for families and owner-occupiers, with a mix of older character homes and more recent builds dotted around the foreshore. If you own a free-standing home here — particularly one built in the 1960s with classic weatherboard construction — understanding what you should be paying for building insurance is well worth your time. This article breaks down a real building-only quote for a 4-bedroom, 2-bathroom home in Lake Illawarra and puts it into context against local, state, and national benchmarks.

Is This Quote Fair?
The quote in question comes in at $1,842 per year (or $195/month) for building-only cover on a 244 sqm free-standing home, with a building excess of $3,000 and a sum insured of $773,000.
Our price rating for this quote is FAIR — Around Average, and the data backs that up. The suburb average premium for Lake Illawarra sits at $1,968/yr, while the median is $1,954/yr. At $1,842, this quote lands comfortably below both figures — about 6% under the suburb average — which is a reasonable result without being a standout bargain.
For context, the cheapest quartile of quotes in this suburb comes in at or below $1,692/yr (the 25th percentile), while the more expensive end reaches $2,188/yr at the 75th percentile. This quote sits in the middle band, which is exactly what a "Fair" rating reflects: you're not overpaying, but there may still be room to shop around and nudge the price down.

How Lake Illawarra Compares
Zooming out to a broader view, the pricing picture becomes even more interesting. You can explore the full data on the Lake Illawarra suburb insurance stats page.
| Benchmark | Premium |
|---|---|
| This Quote | $1,842/yr |
| Lake Illawarra Suburb Average | $1,968/yr |
| Lake Illawarra Suburb Median | $1,954/yr |
| Wollongong LGA Average | $2,751/yr |
| NSW State Average | $9,528/yr |
| NSW State Median | $3,770/yr |
| National Average | $5,347/yr |
| National Median | $2,764/yr |
A few things stand out here. First, the NSW state average of $9,528/yr looks alarming — but averages can be heavily skewed by high-value properties and extreme-risk areas like flood-prone regions or bushfire zones. The state median of $3,770/yr is a more grounded comparison, and this quote sits well below it. You can explore broader NSW home insurance statistics here.
Compared to national benchmarks, the picture is similarly encouraging. The national median is $2,764/yr, and this quote at $1,842 comes in roughly 33% below that figure. Lake Illawarra, while not without its risks (more on that below), appears to be a relatively affordable suburb to insure compared to many parts of Australia.
It's also worth noting that the Wollongong LGA average of $2,751/yr is notably higher than what's being quoted here, which suggests that Lake Illawarra itself may carry a more moderate risk profile than some other suburbs within the same council area.
> Note: The suburb sample size for this analysis is 6 quotes, so while directionally useful, these figures should be treated as indicative rather than definitive.

Property Features That Affect Your Premium
Several characteristics of this property are worth understanding from an insurance perspective.
Weatherboard timber construction is one of the most significant factors. Older weatherboard homes — particularly those built in 1965 — are considered higher risk by insurers due to their susceptibility to fire, rot, and the cost of sourcing period-appropriate materials for repairs. Many insurers apply loadings to weatherboard properties, which can push premiums higher than equivalent brick homes.
Stump foundations are common in older NSW homes and can be a double-edged sword. On the positive side, homes on stumps can be easier to inspect and repair underneath. However, they can be more vulnerable to movement, subsidence, and pest damage over time — all factors that insurers consider when pricing a policy.
Tiled roof is generally viewed favourably by insurers. Terracotta or concrete tiles are durable, fire-resistant, and long-lasting compared to materials like Colorbond or older fibrous cement sheeting. This likely has a positive effect on the premium.
Timber and laminate flooring throughout the home adds to the overall replacement cost estimate, which is reflected in the $773,000 sum insured. Getting this figure right is critical — underinsuring can leave you significantly out of pocket after a major claim.
The granny flat is an important consideration that homeowners sometimes overlook. A secondary dwelling on the property adds to the rebuild cost and complexity of a claim. It's essential to confirm with your insurer that the granny flat is explicitly covered under the building policy, as some policies may require separate disclosure or even a separate policy.

Tips for Homeowners in Lake Illawarra
1. Review your sum insured regularly. Construction costs have risen sharply in recent years across NSW. A sum insured of $773,000 may have been appropriate when the policy was first taken out, but it's worth using a building cost calculator annually to ensure you're not underinsured. Rebuilding a 244 sqm weatherboard home with a granny flat can be surprisingly expensive once you factor in demolition, materials, and labour.
2. Confirm your granny flat is covered. As noted above, the secondary dwelling needs to be explicitly included in your policy. Ask your insurer directly whether the granny flat is covered under the same building sum insured or whether it needs to be listed separately. Don't assume — it's a common gap in coverage.
3. Consider a higher excess to reduce your premium. This quote carries a $3,000 building excess, which is already on the moderate-to-high side. If you have the financial buffer to absorb a larger out-of-pocket cost in the event of a claim, some insurers will offer a meaningful premium reduction in exchange for a higher excess. It's worth running the numbers.
4. Shop the market at renewal time. A "Fair" rating means this quote is reasonable — but it doesn't mean it's the best available. Insurance pricing varies significantly between providers, even for identical properties. Using a comparison platform like CoverClub at renewal time takes only a few minutes and could reveal savings of hundreds of dollars per year.
