Strata Insurance in Australia - What Owners and Committees Need to Know

We’ll keep things approachable and jargon-free so that any property owner or committee member can understand the essentials.

What Does Strata Insurance Cover?

Strata insurance typically covers:

The Building and Common Property (e.g. walls, roof, lobbies, gardens)
Common Area Contents (e.g. foyer furniture, gym equipment)
Public Liability (injuries on common property)
Loss of Rent/Temporary Accommodation (after major damage)

It does not cover:

Personal contents of owners or tenants
Upgrades or improvements inside units (these may need contents insurance)

Optional extras often include:

Office Bearers’ Liability
Fidelity Guarantee
Volunteer Workers Cover
Machinery Breakdown (important if your building has lifts)
Catastrophe Cover
Workers’ Compensation (if applicable)

Always check your building’s policy and definitions carefully!

Is Strata Insurance Legally Required?

Yes, strata insurance is mandatory in all Australian states and territories.

Owners corporations must:

Insure the building for full replacement value
Have public liability insurance (usually at least $10M)

The insurance is organised and paid by the owners corporation, and each owner pays their share through strata levies.

How Strata Insurance Is Organised

Strata insurance is usually arranged by:

The strata committee
The professional strata manager

They often work through:

Insurance brokers who specialise in strata insurance
Underwriting agencies who package strata policies

The insurance policy covers all owners collectively. There’s typically one master policy, not individual ones per lot.

Owners pay the premium via their strata levies, proportional to their unit entitlements.

How Are Strata Insurance Premiums Calculated?

Premiums are influenced by:

Building Sum Insured (the higher the rebuild cost, the higher the premium)
Building Features (e.g. lifts, pools increase costs)
Location (cyclone, bushfire, flood risks)
Claims History (more past claims = higher premiums)
Building Age and Condition
Security Measures (sprinklers, CCTV can lower premiums)
Size and Occupancy (larger buildings, more short-term rentals = higher risk)
Excess Choices (higher excess = lower premium)
Optional Covers Chosen (e.g. machinery breakdown)

Important: Lifts almost always increase premiums because they add expensive equipment and liability risk.

Strata Insurance Fee Breakdown

Strata insurance fees usually include:

Base Premium (risk cost)
GST (10%)
Stamp Duty (varies by state, around 9%-11%)
Broker Commission (commonly ~20% of the base premium)
Broker Fees (sometimes in addition to or instead of commission)
Strata Manager Commission (sometimes a cut from the broker commission)

Example:

Base premium: $7,000
- GST and stamp duty: ~$1,470
- Broker commission: ~$1,400
Total: ~$10,000

Notable Exclusions

Strata insurance typically does not cover:

Personal contents inside individual units
Routine maintenance, wear and tear
Structural building defects or poor workmanship
Gradual earth movement (subsidence)
Flood damage (unless added)
Damage from coastal erosion, war, or nuclear incidents

Always review your policy’s Product Disclosure Statement (PDS).

Who Are the Major Underwriters and Brokers?

Top strata insurers in Australia include:

CHU Insurance (owned by Steadfast, backed by QBE)

Recent Developments and Controversies

Rising Premiums

Climate change (cyclones, floods, bushfires) has caused big premium hikes.
The Cyclone Reinsurance Pool (2022) is helping lower costs in northern Australia.

Commissions and Transparency Issues

ABC’s Four Corners (2024) exposed hidden insurance commissions.
ACCC called for a ban on strata insurance commissions.
Some strata managers and brokers are now offering flat-fee models instead of commission-based.

Cladding and Defects

The flammable cladding crisis made some buildings hard to insure.
Structural defects (e.g. Mascot Towers) show that insurance does not cover poor construction.

Market Consolidation

Fewer insurers are competing in the strata market.
Owners should shop around and demand disclosure of all commissions and fees.

Bottom line: Strata insurance is essential for protecting your building and investment. Stay informed, review your building’s policy each year, ask for fee transparency, and be proactive about building maintenance to keep premiums manageable.
