Lake Illawarra is a relaxed lakeside suburb on the NSW South Coast, sitting between the Illawarra Escarpment and the shores of Lake Illawarra itself. It's a popular spot for families and long-term residents, with a mix of older homes and more recent builds. This article takes a close look at a building insurance quote for a four-bedroom, two-bathroom free-standing home in the area — examining whether the price stacks up, what's driving the premium, and what local homeowners can do to keep costs in check.

Is This Quote Fair?
The quote in question comes in at $1,818 per year (or $193 per month) for building-only cover, with a $3,000 building excess and a sum insured of $773,000.
Our price rating for this quote is FAIR — Around Average, and the numbers back that up. The suburb average premium for Lake Illawarra sits at $1,968/yr, with a median of $1,954/yr. At $1,818, this quote lands below both figures, placing it comfortably in the lower half of the local price range. The suburb's 25th percentile is $1,692/yr, so while there may be cheaper options available, this quote is meaningfully better than what most homeowners in the area are paying.
In short: this isn't a bargain, but it's a reasonable price for the property type and location. There's still room to shop around, but you're not being overcharged.

How Lake Illawarra Compares
To put this quote in proper context, it helps to zoom out and look at the broader picture. You can explore the full data on the Lake Illawarra insurance stats page, the NSW state overview, and national insurance benchmarks.
| Benchmark | Average Premium | Median Premium |
|---|---|---|
| Lake Illawarra (2528) | $1,968/yr | $1,954/yr |
| Wollongong LGA | $2,751/yr | — |
| NSW State | $9,528/yr | $3,770/yr |
| National | $5,347/yr | $2,764/yr |
A few things stand out here. The NSW state average of $9,528/yr looks alarming at first glance, but it's heavily skewed by high-risk and high-value properties across the state — the median of $3,770/yr is a far more representative figure for typical NSW homeowners. Even so, Lake Illawarra's median of $1,954/yr sits well below the state median, suggesting the suburb carries a relatively modest risk profile compared to many parts of NSW.
Compared to the national median of $2,764/yr, Lake Illawarra also comes out favourably. Homeowners here are generally paying less than the national middle ground — a positive sign for the area's insurability.
It's also worth noting that the Wollongong LGA average of $2,751/yr is notably higher than Lake Illawarra's suburb average. This likely reflects the diversity of property types and risk profiles across the broader LGA, including areas with greater flood, storm, or bushfire exposure.

Property Features That Affect Your Premium
Several characteristics of this particular property have a meaningful influence on the premium. Here's what matters most:
Age of Construction (1965) At around 60 years old, this home is well into the territory where insurers apply closer scrutiny. Older homes can have ageing plumbing, wiring, and structural elements that increase the likelihood of a claim. This is one of the more significant premium drivers for this property.
Weatherboard Timber Walls Weatherboard construction is common in older Australian homes and is generally considered a higher risk than brick veneer or full brick, primarily due to fire susceptibility. Insurers typically price this in, and it's likely contributing to the premium here.
Tiled Roof Tiles are generally viewed favourably by insurers — they're durable, fire-resistant, and weather well over time. This is a moderately positive factor for the premium.
Stump Foundation Homes on stumps (also called pier foundations) are common in older NSW properties. While they allow for good airflow and can be practical in flood-prone areas, they can also be more vulnerable to subsidence and require maintenance over time. Insurers consider this when pricing the risk.
Timber and Laminate Flooring The flooring type itself has a modest impact on the sum insured calculation rather than the risk profile directly, but it does factor into rebuild cost estimates.
Granny Flat The presence of a granny flat on the property adds to the overall rebuild value and is reflected in the $773,000 sum insured. It also slightly broadens the scope of what's being covered under the building policy.
Building Size: 244 sqm At 244 sqm, this is a reasonably sized home. The sum insured of $773,000 works out to roughly $3,168 per sqm — a figure that's broadly in line with current construction costs in NSW, particularly for an older home with a granny flat.

Tips for Homeowners in Lake Illawarra
1. Review your sum insured regularly Construction costs in NSW have risen significantly in recent years. Make sure your $773,000 sum insured still reflects what it would actually cost to rebuild your home — including the granny flat — from scratch. Underinsurance is one of the most common and costly mistakes homeowners make.
2. Consider a higher excess to reduce your premium This quote carries a $3,000 building excess. If you have the financial buffer 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. It's worth modelling the trade-off.
3. Maintain your weatherboard exterior Because timber weatherboard walls are a premium risk factor, keeping them in good condition — well-painted, free of rot, and properly sealed — can help when it comes to renewals and claim assessments. Some insurers may also factor in maintenance history.
4. Shop around at renewal time Even with a FAIR-rated quote, there's a meaningful gap between the 25th percentile ($1,692/yr) and 75th percentile ($2,188/yr) in Lake Illawarra. That's nearly $500 per year in potential savings. Loyalty doesn't always pay in home insurance — comparing quotes annually is one of the simplest ways to avoid overpaying.
