Strata Insurance in Australia: Key Gaps Owners Still Face

The critical mechanism to understand is that strata insurance is structured around the common property boundary. In most strata schemes, "common property" is defined precisely by the strata plan registered with the relevant state titles office — and that boundary does not necessarily coincide with the interior walls of your unit. In many older schemes, the common property boundary runs to the inner face of the external walls, meaning the plaster, paint, flooring, and fixtures inside your apartment sit outside the strata policy's scope entirely. This is a structural feature of strata law, not a policy exclusion that can be negotiated away. For a fuller explanation of how strata title defines ownership boundaries, see our guide on Strata Title vs Torrens Title Explained.

Strata policies also typically include common property public liability cover, which protects the body corporate — and by extension lot owners collectively — against third-party injury or property damage claims arising in shared spaces. If a visitor slips on a wet communal staircase and sues, the strata policy generally responds. What it does not cover is a slip inside your own apartment, or damage caused by a leak originating from your unit that affects a neighbour. Those scenarios create personal liability for the individual lot owner, not the body corporate.

It is worth understanding that strata insurance premiums are paid collectively through body corporate levies, and the cost is shared across all lot owners in proportion to their lot entitlements. Many lot owners notice this only as a line item in their quarterly levy notice — without appreciating that the underlying policy protects the building, not their personal assets within it.

The Three Coverage Gaps Every Owner Must Address

The most common gap is contents. Strata insurance does not cover furniture, electronics, appliances, clothing, or any other personal property inside a lot. For owner-occupiers, this means a standard home and contents policy — applied to the unit's interior — is essential. For investors who lease their apartment furnished, a landlord insurance policy that includes contents cover is the appropriate product. An unfurnished rental still warrants landlord insurance for the fixtures and fittings the investor has installed — floor coverings, window treatments, light fittings — which may not be captured by the strata policy depending on how the common property boundary is drawn.

The second gap is lot owner's improvements. If you have renovated your apartment — installing a new kitchen, updated bathrooms, or timber flooring over the original concrete slab — those improvements are almost certainly not covered by the strata policy. Strata insurance is typically written to cover the building as originally constructed, or to a standard specification. Any upgrade above that standard is the lot owner's responsibility to insure separately. This is particularly relevant for investors who have spent materially upgrading a unit to attract higher-quality tenants: the investment in those improvements is uninsured unless a separate policy is taken out.

The third gap is personal liability within the lot. If a guest is injured inside your apartment, or if a burst pipe originating in your unit floods the apartment below and causes substantial damage, your personal liability as the lot owner sits outside the strata policy. A personal liability extension — typically available as part of a contents or landlord insurance policy — addresses this directly. The consequences of being uninsured against a significant water damage claim from a neighbouring lot can be severe, particularly in a high-rise building where one burst pipe can cascade through multiple floors.

Loan Structure, Equity, and Why Insurance Matters More for Leveraged Owners

The interaction between insurance coverage and loan structure is underappreciated by many apartment buyers. An owner who has purchased with a high loan-to-value ratio carries more financial exposure to an uninsured loss than one who owns outright. If an uninsured fire destroys the contents and improvements in your unit, and you are simultaneously servicing a mortgage, you face the cost of replacing those assets from cash flow — without the buffer that equity would otherwise provide. This dynamic is especially relevant for investors who use interest-only loan structures, where repayments are lower but no equity is being accumulated. Our guide on Interest Only vs Principal and Interest — Which Loan Structure is Right? explains how the choice of loan structure affects an investor's overall financial resilience, which in turn affects how much weight a comprehensive insurance policy carries in the overall risk profile.

For first-home buyers entering strata buildings — often the most accessible price point in capital cities — understanding this insurance gap is particularly pressing. A buyer who has stretched to their borrowing limit, relying on LMI or a family guarantee to enter the market, has even less capacity to absorb an uninsured loss. The assumption that the body corporate's strata policy "covers everything" is one of the more costly misconceptions in Australian apartment ownership. Lenders require strata insurance as a condition of settlement, but they do not require the individual lot owner to hold contents or liability cover — that discipline must come from the buyer.
