Is This Quote Fair?

The annual premium for this property comes in at $4,486 per year (or $423/month), covering both building (sum insured: $550,000) and contents ($50,000). Our price rating for this quote is Expensive — Above Average.

To put that in perspective:

  • The WA state average premium is $2,144/yr, with a median of $1,944/yr
  • The national average sits at $2,965/yr, with a national median of $2,716/yr

At $4,486, this quote is more than double the WA state average and roughly 51% above the national average. That's a significant gap, and it's worth understanding why before simply accepting the price — or shopping elsewhere.

That said, context is everything. Millars Well is located within the City of Karratha LGA, where the average home insurance premium is a striking $11,055/yr. Measured against that local benchmark, this quote is actually well below the LGA average — which suggests the property's specific characteristics and the insurer's risk assessment may be working in the homeowner's favour relative to nearby properties.

So while the premium is expensive by state and national standards, it may be quite competitive for the Karratha region specifically. The key takeaway: don't just compare to the national average — always consider your local market context.

You can explore more detailed premium data for this postcode at the Millars Well suburb stats page, or compare across the state on the WA insurance stats page. For a broader view, the national home insurance stats offer useful context on how Australian premiums vary by region.

The Pilbara region commands higher premiums for several structural reasons: it's geographically remote, which increases rebuilding costs significantly; the local economy drives higher labour and materials costs; and while Millars Well itself is not classified as a cyclone risk area, surrounding parts of the Pilbara are — and insurers price regional exposure into their broader risk models.

Property Features That Affect Your Premium

Every property tells a story to an insurer, and this one has several features worth noting:

Double Brick Walls Double brick construction is generally viewed favourably by insurers. It's durable, fire-resistant, and built to last — qualities that can help moderate premiums compared to lighter cladding materials. For a 1985-built home, double brick also signals solid structural integrity, though insurers may factor in the age of the build when assessing maintenance risk.

Steel/Colorbond Roof Colorbond roofing is a popular and practical choice across regional WA. It's resistant to corrosion, relatively low-maintenance, and performs well in high-temperature environments like the Pilbara. Insurers generally consider it a lower-risk roofing material compared to older tile or fibrous cement options.

Slab Foundation A concrete slab foundation is standard for the region and presents minimal additional risk from an underwriting perspective. It's less susceptible to subsidence and termite entry compared to raised timber foundations.

Solar Panels This property includes solar panels, which are increasingly common across Australia. It's important to ensure your policy explicitly covers solar panels — both the panels themselves and any associated inverter equipment. Some policies cover them as part of the building sum insured; others require a separate declaration.

Ducted Climate Control Ducted air conditioning is essentially a necessity in the Pilbara's extreme heat. This system adds value to the building and should be factored into your sum insured to avoid being underinsured in the event of a claim.

Timber/Laminate Flooring Flooring type can influence contents and building claims. Timber and laminate floors are susceptible to water damage, so it's worth confirming your policy covers escape of liquid events comprehensively.

Building Excess: $5,000 | Contents Excess: $5,000 Both excesses are on the higher end of the spectrum. A higher excess typically reduces your premium, but it also means a larger out-of-pocket cost at claim time. Make sure this level of excess is manageable for your household budget.

Tips for Homeowners in Millars Well

1. Review your sum insured carefully At $550,000, the building sum insured needs to reflect the true cost of rebuilding — not the market value of the property. In a remote region like Karratha, rebuilding costs per square metre can be significantly higher than metropolitan areas due to freight, labour, and materials. Consider getting a professional building valuation to ensure you're not underinsured.

2. Confirm solar panel coverage With solar panels installed, check your policy documents carefully. Confirm whether the panels are included under the building sum insured or need to be separately listed. Also verify that the inverter and associated wiring are covered, as these can be costly to replace.

3. Shop around — even if this quote beats the LGA average The fact that this premium is well below the Karratha LGA average is encouraging, but it doesn't mean it's the best available price. Different insurers weight regional risk differently, and comparing multiple quotes can reveal meaningful savings. Use a comparison platform to see what's available for your specific property profile.

4. Consider your excess trade-off With both building and contents excesses set at $5,000, think carefully about whether this is the right balance for you. If you'd struggle to cover a $5,000 excess in an emergency, it may be worth paying a slightly higher premium to bring the excess down. Conversely, if you have a solid emergency fund, the higher excess strategy can save money over time.

Frequently Asked Questions

Why is home insurance so expensive in the Karratha region compared to the rest of WA?

The Karratha LGA — which includes suburbs like Millars Well — has significantly higher home insurance premiums than the WA state average. This is largely due to the region's remoteness, which drives up rebuilding costs through higher labour and materials expenses, as well as freight costs. Proximity to cyclone-risk zones in the broader Pilbara also influences how insurers price regional exposure, even for suburbs not directly classified as cyclone risk areas.

Does home insurance in WA cover solar panels?

Coverage for solar panels varies between insurers and policies. Some policies automatically include solar panels as part of the building sum insured, while others require you to specifically declare them. It's important to check your Product Disclosure Statement (PDS) and confirm that both the panels and the inverter are covered. If they're not explicitly mentioned, contact your insurer to arrange appropriate cover.

What does 'sum insured' mean for home insurance, and how do I know if mine is correct?

The sum insured is the maximum amount your insurer will pay to rebuild or repair your home if it's totally destroyed. It should reflect the full cost of rebuilding — including demolition, materials, and labour — not the market value of the property. In regional areas like Millars Well, rebuilding costs can be substantially higher than in metropolitan areas. A professional quantity surveyor or building valuation service can help you determine an accurate sum insured and avoid being underinsured.

What is a building excess, and how does it affect my premium?

A building excess is the amount you agree to pay out of pocket when you make a claim before your insurer covers the rest. Choosing a higher excess — such as the $5,000 excess in this example — typically reduces your annual premium. However, it also means a larger upfront cost if you need to claim. It's a trade-off between short-term savings and financial readiness at claim time. Make sure your chosen excess is an amount you could comfortably pay in an emergency.

Is a semi detached home insured differently to a freestanding house in WA?

Yes, there are some differences. For a semi detached property, you typically only insure your portion of the building — not the shared wall or the neighbouring dwelling. It's important to clarify with your insurer exactly what is and isn't covered, particularly around shared structures. If you own a strata-titled semi detached, some building cover may be handled through a strata body corporate policy, so you'll need to understand what's already covered before taking out additional building insurance.
