Strata Insurance Costs in 2026: Why Premiums Are Rising and What Owners Can Do
Strata insurance costs in 2026 are climbing faster than most budgets anticipated. Here's why premiums are rising — and the practical steps committees and managers can take to reduce the pressure.
Strata insurance costs in 2026 have become one of the most urgent line items on every owners corporation agenda in Australia. After several years of compounding pressures — extreme weather events, surging construction costs, and a hardening global insurance market — many schemes are receiving renewal notices that bear little resemblance to last year's premiums. Understanding *why* this is happening is the first step to doing something about it.
What Is Driving Strata Insurance Costs in 2026?
1. Replacement-Cost Inflation Has Not Plateaued
Insurance for a strata building is typically written on a "full replacement" basis — meaning the sum insured must cover the cost of demolishing and rebuilding the structure from scratch, not just its current market value. Over the past few years, the construction sector has absorbed significant cost increases across labour, materials, and trades. Even as the pace of general inflation has eased, building replacement costs have remained elevated. If a scheme's sum insured has not been updated to reflect current rebuild costs, it faces the risk of under-insurance — and insurers are pricing that risk into premiums across the board.
Committees should treat a professional replacement-cost valuation as a non-negotiable part of the renewal cycle, not an optional extra.
2. Claims Frequency and Severity Are Both Up
The volume and cost of strata claims has risen substantially. Water damage — from burst pipes, failed waterproofing, and storm events — remains the most common claim category in Australian strata schemes. But the average cost per claim has grown, partly because of the same construction-cost pressures mentioned above (rectification work is more expensive), and partly because ageing building stock is generating more maintenance-related failures.
Liability claims have also grown in complexity. As owners corporations take on greater responsibilities under safety legislation and duty-of-care expectations, claims arising from slip-and-falls, essential-safety-measure failures, and inadequate common-property maintenance are becoming more consequential.
3. A Hardening Global Reinsurance Market
Australian insurers don't carry all their risk alone — they lay much of it off to global reinsurers. After a string of costly natural catastrophe years globally, reinsurance capacity has tightened and its cost has increased. Those costs flow directly into retail strata premiums. Schemes located in regions with elevated exposure to cyclone, flood, or hailstorm are feeling this acutely, but the knock-on effect is being felt across the country.
4. Climate-Related Risk Reclassification
Many insurers are actively repricing risk in postcodes they consider more exposed to weather-related perils. Coastal, flood-prone, and bushfire-adjacent buildings may find themselves in a higher-rated tier regardless of their individual claims history. This is a structural shift in how risk is modelled and underwritten, not a temporary blip.

The Under-Insurance Problem: A Hidden Threat
Under-insurance is one of the most serious — and still underappreciated — risks in Australian strata. If a total-loss event occurs and the sum insured falls materially short of actual rebuild costs, the shortfall falls on owners. Depending on the jurisdiction, owners corporations have a legal obligation to insure the building for its full replacement value. Failing to do so may also expose committee members to personal liability.
The gap between outdated sums insured and real rebuild costs has widened considerably as construction costs have risen. An independent valuation — not a simple CPI uplift — is the only reliable way to know whether your scheme is adequately covered.

What Committees Can Do to Reduce Insurance Pressure
Rising market conditions don't mean committees are powerless. There are practical, evidence-based actions that can reduce premium pressure at renewal and improve the scheme's overall risk profile.
Commission a Current Replacement-Cost Valuation
An up-to-date, professionally prepared valuation gives your insurer accurate data to work with and protects owners from the financial consequences of under-insurance. It also demonstrates that the committee is managing the building responsibly — something underwriters notice.
Tighten Maintenance and Preventive Inspection Regimes
Claims history is a major pricing input. Schemes with a track record of frequent water damage, defect-related losses, or liability incidents will pay more. Proactive maintenance — including regular inspection of plumbing, waterproofing membranes, roof flashings, fire systems and lifts — reduces the likelihood of the events that generate claims. Document all maintenance work and keep records accessible for your insurer or broker.
Review Your Excess Structure
Accepting a higher voluntary excess can reduce premiums, but this needs to be calibrated carefully against the scheme's capacity to self-fund smaller losses. Some committees establish a reserve within the administrative fund specifically to absorb excesses on minor claims, making a higher excess structure financially viable.
Shop the Market Through a Specialist Broker
Strata insurance is a specialist product and not all brokers have deep experience in it. A broker who works extensively with strata schemes will have access to a wider panel of underwriters, understand the nuances of common property coverage, and be able to present your scheme's risk profile in the most favourable light. Don't accept a like-for-like renewal without testing the market.
Address Known Defects and Common Property Risks
Outstanding defects, especially those related to waterproofing, structural elements, or essential safety measures, can influence both insurability and pricing. If your scheme has known issues, a documented remediation plan — even one still in progress — is better than silence. Insurers are more comfortable with a scheme that is actively managing risk than one that appears to be ignoring it.
Improve Essential Safety Measure Compliance
In most Australian states and territories, buildings are required to maintain essential safety measures (ESMs) — fire sprinklers, emergency lighting, exits, and so on — in working order. Non-compliance can affect both your coverage and your liability exposure. Ensure annual ESM reporting is up to date and that any deficiencies are being actively rectified.
Look at Loss-Prevention Upgrades
Some upgrades have a measurable impact on risk — and on premiums. Water-leak detection systems, for example, can identify slow leaks before they become major claims events. Security upgrades can reduce malicious damage losses. Some insurers will factor documented risk-reduction improvements into their pricing.

What to Raise at Your Next AGM
The rising cost of strata insurance is a legitimate agenda item that deserves honest discussion with owners, not just a line in the levy notice. Committees should be prepared to:
- Present the current sum insured alongside an updated or pending valuation
- Explain the market conditions driving premium increases
- Outline the risk-mitigation steps already taken or planned
- Discuss whether the current excess structure remains appropriate
- Consider whether the capital works (sinking) fund adequately covers potential excess payments
Transparent communication builds trust and reduces the likelihood of levy disputes when owners see a significant premium increase.

The Bottom Line
Strata insurance costs in 2026 reflect a genuine convergence of structural pressures — not a temporary spike that will resolve itself at the next renewal. Committees and strata managers who take a proactive, evidence-based approach to risk management, valuation accuracy, and broker engagement will be far better positioned than those who simply accept whatever arrives in the renewal pack.
Platforms like Orveya can help strata managers and committees maintain the maintenance records, inspection logs, and compliance documentation that support a stronger risk profile at renewal time.
The cost of insurance is partly a function of the market — and partly a function of how well your scheme is managed. Focus your energy on what you can control.
