Is This Quote Fair?

The quote in question came in at $2,240 per year (or roughly $215 per month) for combined home and contents cover, with a building sum insured of $839,000 and contents valued at $81,000. Both the building and contents excess are set at $1,000.

How South Wentworthville Compares

To put this quote in proper context, it helps to zoom out and look at the broader pricing landscape.

BenchmarkPremium
This quote$2,240/yr
Suburb average (2145)$4,609/yr
Suburb median (2145)$3,993/yr
Suburb 25th percentile$3,117/yr
LGA average (Parramatta)$2,031/yr
NSW average$9,528/yr
NSW median$3,770/yr
National average$5,347/yr
National median$2,764/yr

A few things stand out here. The NSW state average of $9,528 per year is extraordinarily high compared to the median of $3,770 — a sign that a small number of very expensive policies (often in high-risk flood or bushfire zones) are skewing the mean upward. This is a common pattern in New South Wales, where geographic risk varies enormously from the coast to the mountains to Western Sydney.

At the national level, the average sits at $5,347 but the median is a more modest $2,764. This quote, at $2,240, sits just below the national median — which is a solid result for a property of this size and value.

The Parramatta LGA average of $2,031 is notably lower than the suburb average, suggesting that South Wentworthville's postcode may attract slightly higher premiums than some neighbouring areas within the same local government area. This could relate to localised risk factors such as storm water drainage, proximity to waterways, or claims history in the area.

It's worth noting that the suburb sample size here is 12 quotes, so while directionally useful, these figures may shift as more data comes in. You can explore the latest figures on the South Wentworthville stats page.

Property Features That Affect Your Premium

Several characteristics of this property are likely working in the homeowner's favour when it comes to pricing.

Brick veneer construction is generally viewed favourably by insurers. While not as robust as full double-brick, brick veneer offers solid fire resistance and structural integrity compared to lightweight cladding or weatherboard, which can attract higher premiums. Combined with a tiled roof, this property sits in a relatively low-risk construction category — tiles are durable, fire-resistant, and less susceptible to storm damage than corrugated iron in most conditions.

The slab foundation is another plus. Slab-on-ground construction is common in Western Sydney and tends to be straightforward for insurers to assess, with fewer concerns about subsidence or underfloor moisture compared to older pier-and-beam homes.

The property was built in 2006, which puts it in a comfortable middle ground — modern enough to comply with updated building codes but not so new that replacement costs are at a premium. At 214 square metres, it's a generously sized semi detached home, and the inclusion of ducted climate control adds some value to the building sum insured.

One feature worth flagging is the granny flat. Depending on the insurer and the policy wording, a granny flat may or may not be automatically covered under a standard home insurance policy. Some insurers include it within the main dwelling sum insured, while others treat it as a separate structure requiring additional cover. Homeowners should confirm this with their insurer explicitly — particularly if the granny flat is rented out, as this can affect both the policy terms and the premium.

The absence of a pool and solar panels keeps things simpler. Pools introduce liability considerations, and solar panel systems can complicate replacement cost calculations, so their absence here likely contributes to the competitive premium.

Tips for Homeowners in South Wentworthville

1. Confirm your granny flat is covered Before assuming your policy covers the granny flat, read the product disclosure statement carefully or call your insurer. If the flat is used for rental income, you may need landlord insurance or a specific endorsement on your home policy.

2. Review your sum insured regularly Building costs in Western Sydney have risen significantly in recent years. A sum insured of $839,000 for a 214 sqm brick veneer home should be revisited annually to ensure it reflects current construction costs. Underinsurance is one of the most common — and costly — mistakes homeowners make.

3. Don't set and forget your premium This quote is competitively priced today, but insurers adjust their rates each year at renewal. It's worth comparing quotes annually rather than simply accepting the renewal offer. Even a 30-minute comparison exercise can save hundreds of dollars.

4. Check for flood and storm cover Parts of the Parramatta LGA have experienced significant storm and flash flooding events. Make sure your policy explicitly includes storm surge and flood cover, and understand any specific exclusions that may apply to your property's location.

Frequently Asked Questions

What is the average cost of home insurance in South Wentworthville NSW 2145?

Based on recent quote data, the average home insurance premium in South Wentworthville (postcode 2145) is around $4,609 per year, with a median of $3,993 per year. Premiums can vary significantly depending on the property type, construction materials, sum insured, and the insurer you choose.

Is a granny flat covered under standard home insurance in Australia?

Not always automatically. Some insurers include a granny flat as part of the main dwelling if it's on the same title and not separately tenanted. Others require it to be listed as a separate structure or may exclude it entirely if it generates rental income. Always check your Product Disclosure Statement and confirm coverage with your insurer directly.

Why is the NSW average home insurance premium so much higher than the median?

The NSW average premium is heavily skewed upward by properties in high-risk areas — such as flood-prone regions, bushfire zones, and coastal areas — which attract very high premiums. The median is a better reflection of what most NSW homeowners actually pay, and is considerably lower than the mean average.

Does brick veneer construction reduce my home insurance premium?

Brick veneer is generally considered a lower-risk construction type by insurers compared to weatherboard or lightweight cladding, due to its fire resistance and structural durability. This can contribute to a more competitive premium, though the overall rate depends on many other factors including location, roof type, and claims history.

How often should I review my home insurance sum insured?

You should review your building sum insured at least once a year, ideally before your renewal date. Construction costs in Australia have risen sharply in recent years, and an outdated sum insured could leave you significantly underinsured in the event of a total loss. Use a building cost calculator or speak with a quantity surveyor if you're unsure of the current replacement value.
