Our rating for this quote is FAIR — Around Average, and the data backs that up. Across 22 quotes sampled for the Saint Marys 2760 postcode, the suburb average sits at $2,222/yr and the median at $2,133/yr. This quote lands almost exactly on the suburb average — just $14 below it — which places it comfortably within the middle band of what local homeowners are paying.
To put it in percentile terms: the suburb's 25th percentile is $1,916/yr and the 75th percentile is $2,442/yr. At $2,208, this quote falls between the median and the 75th percentile, meaning roughly half of comparable Saint Marys properties are being quoted less, and about a quarter are being quoted more.

How Saint Marys Compares
One of the most striking takeaways from this data is just how much cheaper Saint Marys is compared to the rest of New South Wales — and indeed the country.
| Benchmark | Average Premium |
|---|---|
| Saint Marys (2760) | $2,222/yr |
| Blacktown LGA | $2,135/yr |
| NSW State Average | $3,801/yr |
| National Average | $2,965/yr |
The NSW state average of $3,801/yr is a whopping 71% higher than the Saint Marys suburb average. Even compared to the national average of $2,965/yr, Saint Marys comes in about 25% cheaper. Much of this gap is driven by high-risk coastal and flood-prone areas pushing up state and national figures — regions where premiums can run well into the thousands.
Within the Blacktown LGA, Saint Marys is broadly consistent with the local average of $2,135/yr, suggesting the suburb doesn't carry any unusual localised risk loading compared to its neighbours.

Property Features That Affect Your Premium
Several characteristics of this particular property will be influencing the quoted premium — for better or worse.
Weatherboard Timber Walls
The external walls are weatherboard wood, which is one of the more common construction types in older Western Sydney homes. Timber-clad homes are generally considered a moderate-to-higher risk by insurers compared to brick veneer or full brick, primarily due to fire susceptibility and the potential for rot or deterioration over time. This can nudge premiums slightly higher.
Tiled Roof
A tiled roof is viewed favourably by most insurers. Tiles are durable, fire-resistant, and long-lasting — particularly compared to Colorbond or older fibrous cement sheeting. This is a positive factor for the premium.
Slab Foundation
A concrete slab foundation is considered standard and low-risk in most Australian suburban environments. It provides a stable base and doesn't carry the same concerns as older stumped or suspended timber floors.
Timber and Laminate Flooring
The timber and laminate flooring throughout the home contributes to a higher replacement cost, which is reflected in the $624,000 sum insured. Quality timber floors are more expensive to repair or replace than basic carpet, so this is worth keeping in mind when reviewing your sum insured.
Ducted Climate Control
This property has ducted climate control, which adds meaningful value to the building sum insured. Ducted systems are expensive to replace — often $10,000–$25,000+ — and their inclusion in a building policy is an important coverage consideration.
Built in 1990
At around 35 years old, this home sits in a middle age bracket. It's old enough that some building components (plumbing, electrical, roofing) may be approaching end-of-life, but not so old as to attract the significant age loadings that pre-1970s homes sometimes face.

Tips for Homeowners in Saint Marys
1. Review Your Sum Insured Annually
With construction costs rising significantly over recent years, a sum insured set even two or three years ago may no longer be sufficient to fully rebuild your home. The $624,000 figure here appears reasonable for a 205 sqm home with ducted air conditioning and timber flooring, but it's worth using a building cost calculator to verify this each year at renewal.
2. Consider Increasing Your Excess to Lower Your Premium
This quote carries a $3,000 building excess. If you have the financial capacity to cover a higher out-of-pocket amount in the event of a claim, opting for a higher excess — say $5,000 — could reduce your annual premium meaningfully. Just make sure the savings justify the additional risk exposure.
3. Don't Overlook the Value of Contents Cover
This quote is for building only. If you don't have a separate contents policy in place, your furniture, appliances, clothing, and personal belongings have no protection. Many insurers offer a discount when you bundle building and contents together, so it's worth getting a combined quote for comparison.
4. Shop Around at Renewal Time
Even though this quote is rated "Fair," that doesn't mean it's the best available price for this property. Insurers use different rating models, and the spread between the 25th and 75th percentile in Saint Marys — from $1,916 to $2,442 — shows there's real variation in the market. Comparing multiple quotes before renewing could save you $300 or more per year.
