Strata insurance is compulsory for every owners corporation in Australia, yet most lot owners have only a vague understanding of what it actually covers — and a dangerously incomplete picture of what it does not. The building policy arranged by your owners corporation or body corporate satisfies a legal requirement under strata legislation in every state and territory, but that legal compliance is not the same as personal financial protection. The gap between what the strata policy covers and what an individual owner actually needs is wide enough to cost tens of thousands of dollars in an uncovered claim.
What Strata Building Insurance Actually Covers
Strata building insurance is a single policy arranged collectively for the entire scheme — the apartment block, townhouse complex, or mixed-use building — and it covers the structure that all lot owners share. This includes the external walls, roof, foundations, common-area fitouts such as lobbies and lifts, common-area fixtures, swimming pools, and the fabric of the building up to the internal face of the lot boundary. In most states, coverage extends to original fixtures within the lot itself — the original kitchen cabinetry, bathroom tiles, and built-in wardrobes that were present when the building was first registered — though the precise boundary varies by jurisdiction.

The collective nature of strata insurance is both its strength and its limitation. Because premiums are pooled across all lots, each individual owner benefits from a level of building cover they could not arrange as cheaply alone. The policy typically covers events such as fire, storm, water damage from burst pipes, malicious damage, and public liability for incidents on common property. Public liability is particularly important: if a visitor slips on a wet lobby floor and pursues a damages claim, the strata policy responds — not the individual owner's personal policy.
For buyers evaluating a strata property, understanding the scope of building cover is a due-diligence step that sits alongside reviewing the owners corporation records and the strata financial statements. Both should happen before exchange of contracts. The settlement process — including your legal and due-diligence obligations — is explained in detail in our guide to Conveyancing Explained — The Australian Property Settlement Process. Knowing what the strata policy covers before you buy is far less stressful than discovering a coverage gap after you have settled.
Buyers should also note that strata insurance is funded through the owners corporation levies — the quarterly or annual amounts each lot owner contributes. A building that has recently faced a large uninsured event, or one with a history of claims that has pushed premiums sharply higher, will show up in the levy history. Reviewing three to five years of levy notices and the body corporate's sinking fund balance gives a clearer picture of the true ongoing cost of ownership than the strata levy alone suggests.
The Exclusions That Catch Owners Off Guard
The most common and costly misconception in strata ownership is assuming that because the building is insured, the owner's personal contents and improvements are also covered. They are not. The strata policy covers the structure and common areas — it stops at the internal face of the walls, the underside of the floor above, and the top of the floor slab. Everything inside that shell that the owner has added, replaced, or upgraded sits outside the strata policy's scope. Renovated kitchens, upgraded bathroom vanities, timber flooring laid over original tiles, custom built-ins, high-end appliances: none of these are covered by the building policy if damaged or destroyed.
This exclusion is not a technicality — it is a structural feature of how strata insurance is designed. The logic is sound: if every owner's individual improvements were covered by the collective policy, the premium burden on all owners would rise to account for widely varying levels of fit-out. Instead, the policy sets a baseline that corresponds roughly to the original construction standard, and owners who have improved their lots beyond that baseline must insure the difference themselves. This is a frequently misunderstood distinction that leads to genuine financial hardship when a fire or flood claim reveals the gap.

Other significant exclusions include: damage caused by gradual deterioration or wear and tear (including longstanding water ingress that has not been properly reported); damage caused by pests such as termites; loss of rental income by individual lot owners (the building policy does not compensate you if your unit is uninhabitable after a covered event and you lose rent in the interim); and theft from within the individual lot. Short-term rental platforms such as Airbnb introduce additional complexity — standard strata policies frequently exclude or severely restrict coverage for damage caused by paying guests, a point that can result in a denied claim even where the building policy would otherwise respond.
The strata building policy exists to rebuild the structure — not to replace what owners have invested inside it. Every improvement beyond original construction standard, every item of personal property, and every dollar of rental income lost during a claim must be covered by policies the individual owner arranges entirely separately from the owners corporation.
The Three Policies Every Strata Lot Owner Should Hold
Given the exclusions above, responsible strata ownership requires three distinct layers of coverage beyond the building policy. The first is contents insurance, which covers the owner's personal belongings — furniture, clothing, electronics, artwork — as well as any improvements made to the lot beyond original standard. If you have renovated your apartment and the fit-out is now worth materially more than it was at original construction, a contents policy with a building-improvements extension is essential. Renters living in strata properties are in the same position: the building policy does not cover their possessions at all, and a separate contents policy is the only protection available to them.
The second essential policy for strata owners who rent their lots to tenants is landlord insurance. This covers loss of rental income if the property becomes uninhabitable after an insured event, intentional damage caused by tenants, theft by tenants, and legal liability as a landlord. Standard contents insurance does not include these provisions, and many landlords — particularly those new to investment property — incorrectly assume the building policy fills this role. It does not. A comprehensive guide to what landlord insurance covers and how to choose the right policy is available in our Property Insurance Guide. For a full breakdown of the landlord insurance market, see the APF guide to Landlord Insurance in Australia.
The third coverage layer is personal liability insurance. While the strata policy covers public liability on common property, it does not respond to liability claims arising from incidents inside the individual lot. If a guest injures themselves inside your apartment and pursues a personal injury claim against you as the owner, the strata policy is silent. A home and contents policy typically includes personal liability cover as a standard feature, so owners who hold adequate contents cover generally have this layer addressed — but it is worth confirming the liability limit is sufficient given the value of the assets being protected.
Owners in complexes with shared facilities — gyms, rooftop terraces, car stackers, electric vehicle charging infrastructure — should pay particular attention to whether those specific assets and any associated liability are explicitly included in the strata policy schedule. As these facilities become more common in newer strata developments, coverage questions around them are increasingly unresolved at the scheme level, and individual owners can face unexpected exposure to levy special assessments when the building policy responds partially or not at all to a related claim.
How to Check Your Strata Policy and Fill the Gaps
Every lot owner in a strata scheme has the right to inspect the building insurance policy and the certificate of currency — request these from your owners corporation manager if they are not routinely distributed. Reading the policy schedule carefully will reveal the insured sum, the event categories covered, any exclusions specific to your building type, and the excess applicable to each claim type. A very high excess — the amount deducted from every claim before the insurer pays — can make the policy effectively useless for smaller claims that nonetheless cause real financial damage, such as internal water damage from a plumbing fault in a neighbouring lot.
Once you understand what the strata policy does and does not cover, the process of filling the gaps with personal contents and landlord cover becomes straightforward. Compare products across at least two or three insurers, confirm that any improvements you have made to the lot are captured in your contents sum insured, and review your cover annually — particularly after any renovation work. The cost of maintaining adequate personal cover in a strata setting is modest compared with the cost of a single uninsured claim. Buyers researching strata property for the first time can also benefit from engaging a buyer's agent who is experienced with strata due diligence, as insurance adequacy and levy health are both factors a good buyer's agent will assess before recommending an offer.
The fundamentals of strata insurance coverage have remained stable across Australian jurisdictions, but the risk environment for strata buildings has grown more complex — more shared facilities, more short-term rental activity, and more renovation work inside individual lots than at any point in the recent history of apartment living in Australia. Owners who take the time to understand both what their building policy covers and what it explicitly does not will be in a materially stronger position when a claim event occurs — which, across a large strata scheme over many years, is a matter of when, not if.
