Strata insurance is mandatory across every Australian state and territory for any building subdivided under a strata or community title scheme — yet the policy that the body corporate takes out on behalf of all lot owners routinely leaves individual owners significantly underinsured. The strata building policy covers the common fabric of the building: the external walls, roof, shared facilities, and common property. It does not cover what is inside your front door, what you have done to your lot since settlement, or your personal liability as an occupier. For the estimated two million Australians living and investing in strata-titled properties, understanding exactly where the body corporate policy ends — and where personal cover must begin — is one of the most important and most frequently misunderstood aspects of property ownership in Australia.
What the Body Corporate Strata Policy Actually Covers
A strata insurance policy is arranged and paid for by the owners corporation (also called the body corporate), funded through levies collected from all lot owners. The policy is legally required to cover the building as originally constructed, meaning the structural shell, common areas such as lifts, foyers, car parks, pools, gyms, and shared utilities infrastructure. It must also include public liability cover for incidents occurring in common areas — if a visitor slips in the foyer and sues, the strata policy responds. In most states, the insured amount must reflect the full replacement value of the building, which is typically assessed by a qualified valuer at regular intervals, commonly every three to five years.
The critical phrase here is "as originally constructed." This means the strata policy covers the building as it was when the subdivision was registered — the standard finishes, standard fixtures, and the structural fabric of each lot. If the building was constructed with basic tiles, basic benchtops, and standard bathroom fittings, the strata policy will reinstate to that standard after a covered loss such as a fire or major flood event. Any upgrades you have made — engineered timber floors, a renovated kitchen, a new bathroom — are your responsibility, not the body corporate's. This distinction is widely misunderstood by both owner-occupiers and investors, who often assume their renovated lot is fully covered under the strata policy simply because strata insurance is compulsory.
For investors, understanding this boundary has direct financial consequences. An investment property with renovated interiors that suffers a fire, burst pipe, or storm damage may be reinstated only to its original specification under the strata policy. The gap between original specification and current fitout is an uninsured loss unless the investor holds their own contents and improvements policy. Before purchasing a strata lot — particularly an older one that has been renovated by previous owners — it is worth clarifying with the body corporate what the current building replacement sum insured reflects, and whether any improvements register have been maintained. For further detail on how strata ownership structures work, see the APF guide to Strata Title vs Torrens Title Explained.
It is also worth noting that strata policies vary considerably in their inclusions depending on the insurer and the building's risk profile. Older buildings, those in flood-prone postcodes, or those with combustible cladding may carry exclusions or higher excesses that the average lot owner is unaware of until a claim is lodged. Lot owners have the right to request a copy of the Certificate of Currency and the full policy schedule from their body corporate — a step that relatively few owners take proactively.
The Four Coverage Gaps Every Strata Owner Faces
The most common gap is contents. The strata building policy does not cover furniture, appliances, personal belongings, or any fixtures that are considered "loose" rather than structurally fixed. For owner-occupiers, a standard home and contents policy purchased individually fills this gap. For landlords renting out a strata apartment, a dedicated landlord insurance policy is the appropriate product — it covers not only contents (if furnished) but also loss of rental income following a covered event, tenant default, and damage caused by tenants. A standard home and contents policy does not typically respond to rental income claims, making the distinction between product types material for investors.
The second gap is improvements and betterments. As discussed, any structural or cosmetic upgrade made after the original construction — whether by the current or a previous owner — is generally excluded from the strata building policy. Owners who have installed ducted air conditioning, replaced windows with double glazing, or retiled bathrooms need to account for these improvements either through a separate improvements policy or by ensuring their contents insurer specifically extends cover to owner-installed fixtures. This is an area where underinsurance is particularly common in established apartment markets, where decades of renovation work by successive owners has created a material difference between the original specification and the current fitout.
The third gap is personal liability within the lot itself. The strata building policy provides public liability cover for common areas. It does not extend that cover to incidents occurring inside your lot. If a tradesperson is injured inside your apartment, or a guest is hurt due to a defect that is your responsibility to maintain rather than the body corporate's, the strata policy is unlikely to respond. Individual lot owners need their own liability cover, which is typically included as a feature of home and contents or landlord insurance policies. For investors managing multiple strata properties, this is a risk that compounds across the portfolio.

The fourth gap is temporary accommodation or loss of rent following a building-wide event. While the strata policy may cover damage to the building after a covered loss, the policy does not automatically provide for your accommodation costs while the building is repaired. Some strata policies include a loss of rent or temporary accommodation benefit as a listed extension — but many do not, and the benefit amount is often capped at a level that does not reflect current rental market rates. Owner-occupiers and investors alike should verify whether this benefit exists under the current strata policy, and ensure any shortfall is covered under their own policy.
Background: Strata Insurance in the Broader Property Ownership Context
Strata title as a legal concept was first introduced in New South Wales in 1961 and subsequently adopted across all Australian states and territories. It was designed to allow individual ownership of lots within a multi-unit building while providing a collective mechanism for managing and insuring the shared structure. Today, strata and community title schemes accommodate a substantial share of Australia's housing stock, particularly in capital city markets where apartment living has expanded significantly over the past three decades. The legislative frameworks governing strata insurance obligations differ modestly between jurisdictions — Queensland, Victoria, New South Wales, and Western Australia each have their own strata management acts — but the core insurance requirement is consistent: buildings insurance covering the full replacement value of the common and lot structures is mandatory.
What has changed over time is the complexity of what strata buildings contain. Early strata buildings were simple walk-up apartment blocks with minimal shared facilities. Contemporary strata developments in major cities can include swimming pools, rooftop terraces, concierge services, car stackers, and embedded energy networks — all of which increase the insurance complexity and the premium the building attracts. This growing complexity is one reason lot owners are well advised to read the strata policy carefully rather than assuming that mandatory coverage equals comprehensive coverage. For those weighing the cost implications of buying into a strata scheme — including the stamp duty payable on purchase — the Stamp Duty in Australia — State by State Guide explains how transfer duty is calculated across each jurisdiction.
Practical Steps for Strata Owners and Investors
The single most important step a strata lot owner can take is to obtain and read the current strata insurance Certificate of Currency and policy schedule. This document confirms the insurer, the sum insured for the building, the public liability limit, what exclusions apply, and what extensions are included. Many owners never request this document, leaving them unaware of material exclusions or under-insurance until a claim event forces the issue. Most body corporates are obliged by legislation to provide this on request — and in some states, it must be made available proactively at annual general meetings.
Once the strata policy scope is understood, the next step is to assess the gap. For owner-occupiers, a home and contents policy should at minimum cover personal belongings, any improvements made to the lot, and personal liability within the lot. For investors, a landlord insurance policy is the appropriate vehicle, covering tenant-related risks including default, intentional damage, and loss of rental income — risks that no strata policy addresses. It is also worth reviewing whether the strata building sum insured has been updated recently. Buildings that have not been revalued in several years may carry a sum insured that no longer reflects actual replacement costs, which have risen materially across most Australian markets in recent years due to construction cost inflation.
Strata insurance is compulsory — but compulsory does not mean comprehensive. The body corporate policy is designed to protect the shared asset, not the individual owner's interests inside their lot. The gap between what the building policy covers and what the owner actually needs is where most strata underinsurance occurs.
Finally, investors considering strata property acquisitions should factor insurance-related costs into their due diligence before exchange. Reviewing the strata levy schedule — which includes the insurance levy component — provides insight into what the building currently pays for cover and whether any special levies have been raised to address insurance shortfalls or building defects. A building with a history of claims, unresolved defects, or cladding issues may face restricted insurer appetite and significantly elevated premiums that flow directly into owner levies. A buyer's agent with experience in strata properties can assist with this due diligence process.
