One of the most common questions from first-time buyers and property investors in Sydney is: what exactly is the difference between building insurance and home and contents insurance — and which one do I need?
The short answer: building insurance covers the structure; contents insurance covers what’s inside it. But the detail matters, because gaps between the two are where expensive claims fall through.
Building Insurance: What It Covers
Building insurance (sometimes called home insurance or structure insurance) covers the physical structure of your property — everything that would stay if you picked the building up and turned it upside down.
This includes:
- Walls, roof, floors, and ceiling
- Windows and doors
- Fixed kitchen and bathroom fittings (sinks, baths, built-in cabinetry)
- Garages, carports, and garden sheds on the same land title
- Fences and retaining walls (check policy limits — some sub-limit these)
- Swimming pools and fixed outdoor structures
- Pipes, wiring, and permanent fixtures
Building insurance protects against events like fire, storm damage, flooding (check your specific policy), earthquake, lightning strike, impact from vehicles or aircraft, and malicious damage.
What building insurance does not cover: the belongings inside the house, portable items, or damage caused by gradual wear and tear.
Contents Insurance: What It Covers
Contents insurance covers movable personal property — everything that would come with you if you moved out of the house.
This typically includes:
- Furniture, appliances, and whitegoods
- Clothing and personal effects
- Electronics (TV, laptops, phones — often with limits on portables)
- Jewellery and valuables (usually with a sub-limit; high-value items need to be scheduled separately)
- Sporting equipment and musical instruments
- Curtains and blinds (some policies include these; others treat them as building fixtures)
Contents insurance usually covers loss or damage from fire, theft, storm, and accidental breakage (if you select accidental damage cover).
Combined Home and Contents: The Standard for Owner-Occupiers
Most owner-occupiers in Sydney take out a combined home and contents policy — a single policy from one insurer that bundles building and contents cover. This is generally the most cost-effective structure and simplifies the claims process (you only deal with one insurer, not two).
For a typical Sydney house, a combined policy might cost $2,000–$3,500 per year depending on the property’s rebuild value, postcode, sum insured for contents, and excess level selected.
Investors: Why You Need Landlord Insurance Instead
If you’re renting your property out, a standard home and contents policy is not adequate and may be voided entirely. Most standard policies include a condition that the property must be used as your principal place of residence, or as a short-term holiday rental with restrictions.
For investment properties, you need a landlord insurance policy, which:
- Adds malicious damage by tenants
- Includes liability cover as a landlord (not just an occupier)
- Optionally covers rent default and tenant legal liability
- Is tax deductible as a rental property expense

Strata Units: The Most Misunderstood Scenario
If you own a unit, apartment, or townhouse in a strata scheme, the owners corporation takes out a strata insurance policy that covers the building structure. This means:
- You don’t personally need to insure the building fabric
- The strata policy covers shared areas, the external structure, and common property
- But: it does not cover your internal fixtures, your contents, or your personal liability
Unit owners should take out a strata contents policy (or strata home insurance) that covers:
- Internal improvements you’ve made (new flooring, renovated kitchen)
- Your personal belongings
- Personal liability within the lot
If you’re an investor renting out a strata unit, add a strata landlord policy rather than a standard contents policy.
What “Sum Insured” Means — and Why Getting It Right Matters
The sum insured on a building policy is not the market value of your property. It’s the cost to rebuild the structure from the ground up, including:
- Demolition and debris removal
- Architect and council fees
- Construction costs at current rates
In Sydney, per-square-metre rebuild costs have risen sharply since 2022 due to supply chain pressures and labour costs. Current estimates for a standard brick dwelling in Sydney run from $2,800–$4,500/sqm depending on finish quality and suburb.
Critically, the land value is not included in the sum insured calculation — you only need to insure the structure. Many people make the mistake of using the total purchase price (land + structure) as their sum insured, which leads to severe over-insurance.
Use your insurer’s online rebuild calculator or commission a quantity surveyor report to get an accurate figure. Review it every 2–3 years.
Comparing Policies: What to Check
When comparing building or combined home and contents policies, look beyond the premium:
Defined events vs. accidental damage cover. A defined events policy only covers the risks specifically listed. Accidental damage adds a broader catch-all. The latter costs more but significantly reduces the chance of a denied claim.
Flood definition. Policies differ on whether “flood” includes storm surge, river flooding, and flash flooding. Since the 2022 NSW floods, this has become a major issue in certain Sydney postcodes. Read the PDS carefully.
Excess. A higher excess lowers your premium but increases out-of-pocket costs at claim time. For catastrophic events, a $5,000 excess may be manageable — for frequent small claims, it becomes expensive.
New-for-old replacement. Most quality policies replace damaged contents with new equivalents (not depreciated value). Some budget policies pay indemnity value (depreciated), which can be significantly lower.
Portables and valuables. Base policies often cap cover for laptops, cameras, and jewellery at $1,000–$3,000 per item. Valuable items should be separately scheduled (listed on the policy) for their full replacement value.
The Bottom Line
| Scenario | What You Need |
|---|---|
| Owner-occupier (house or townhouse) | Combined home and contents |
| Owner-occupier (strata unit) | Strata contents / strata home insurance |
| Investor (house or townhouse) | Landlord insurance (building + landlord liability + rent cover) |
| Investor (strata unit) | Strata landlord insurance |
If you’re unsure whether your current policy is adequate — particularly if you’ve recently renovated, changed tenancy status, or bought a property in a flood-affected postcode — it’s worth a 30-minute review with a general insurance broker.
