$254 million over budget is the number to anchor on#

Suncorp's full-year result, posted on 12 August 2026, is the clearest single document a landlord has for pricing Q4 2026 renewals. Group gross written premium rose 2.7% to $15.407 billion (Reinsurance News, 12 August 2026). Net profit after tax was $1.027 billion, down 28%. The headline figure a landlord has to understand is not the premium growth number or the profit number. It is the natural hazard overrun.

Suncorp set a $1,770 million natural hazards allowance for FY26. Actual natural hazard costs came in at $2,024 million. That is $254 million over the budget it told the market to expect at the start of the financial year. The group responded to 32 weather events, 18 of them declared natural hazard events over $10 million each, and processed more than 120,000 claims across Australia and New Zealand.

For a landlord, the mechanics flow in one direction. An insurer that overran its hazard budget by $254 million in FY26 is going to reset its FY27 budget, lock in reinsurance at the new price, and push the cost back through the premium stack over the next 12 months. Suncorp has already set the FY27 allowance at $1.8 billion, which is above the FY26 budget but below the FY26 actual, so the implicit assumption is a reversion toward long-run averages. If the actual sits above $1.8 billion again, the pricing round that lands on Q1 2027 renewal notices gets harder, not softer.

The group guidance says the direction of travel is set. For FY27, Suncorp has flagged GWP growth of about 3% to 5% and an underlying insurance trading ratio in the upper half of its 10% to 12% target range (Insurance News, August 2026). On a landlord policy that currently costs $2,640 a year, a 3% to 5% headline move is a $79 to $132 base increase before any postcode or claims adjustment.

IAG's 7.6% is the broader market baseline#

Suncorp is only half the market. IAG's FY26 result, posted 13 August 2026, showed group gross written premium up 7.6% to $18.412 billion (Share Cafe, 13 August 2026). Australian Retail GWP was $10.308 billion. That number includes $1.272 billion from the recently acquired RACQ business, which lifts the headline. On the pre-RACQ underlying book the growth was closer to 4.5%, which is the figure to work from if you are modelling the trajectory of your own renewal.

NPAT fell to $1.022 billion from $1.359 billion in FY25. The underlying insurance margin was 15%, inside the guidance range. IAG held the dividend at 32 cents, up from 31 cents.

For FY27, IAG reaffirmed GWP growth guidance of 5% to 8% and a reported insurance margin of 14.5% to 16.5%. That 5% to 8% is a higher baseline than Suncorp's 3% to 5%. The gap between the two baselines is what you should expect to see when you shop a renewal: an IAG-brand policy (NRMA, CGU, SGIO, SGIC, Coles) is likely to come back with a steeper headline move than a Suncorp-brand one (AAMI, GIO, Apia, Shannons), all else equal. The gap narrows once you adjust for postcode risk, loyalty, no-claim history and the specific line item mix on your policy, but the baseline direction is the one to read into first.

Compare the Market's 14.78% is the renewal benchmark#

The clearest customer-side read on where this all lands is Compare the Market's July 2026 index. On a standard scenario (a four-bedroom brick veneer home insured for $700,000 with $80,000 in contents), average indicative home and contents quotes across national capitals rose from $2,529.43 in June 2025 to $2,903.36 in June 2026 (Compare the Market, 16 July 2026). That is a 14.78% rise over 12 months on a like-for-like scenario.

The city split tells the geographic story a landlord has to price into their own renewal:

• Sydney posted the largest dollar rise, $334.01 in annual premium.
• Adelaide posted the largest percentage rise at 14.53%.
• Brisbane posted the smallest percentage rise at 10.66%.
• Hobart, Perth, Darwin and Canberra sat between those ranges on both metrics.

Those numbers are home and contents, not landlord. Landlord-specific policies carry the home-and-contents base plus rent default cover, additional liability lines, loss of rent, malicious damage by tenants, and in some policies a theft of fixtures line. The home-and-contents base is the single biggest driver of landlord-policy movement, so a 14.78% capital city base increase feeds through to roughly a 10% to 13% move on the full landlord bill once the specialist landlord-only lines (which have been moving more slowly) are blended in.

On Canstar's March 2026 benchmark, the national average annual landlord premium stood at $2,640 for houses and $432 for units at the point just before this move. A 10% to 13% blended increase takes the house figure to roughly $2,904 to $2,983, and the unit figure to roughly $475 to $488. For a landlord with a four-property portfolio, that is a line-item increase of around $1,100 to $1,400 across the book, before any location-based risk adjustment.

Postcode-level pricing is the single hardest shift to push back on#

The structural shift to be aware of in 2026 is not the headline rate. It is the move insurers have made toward postcode-level pricing on climate-exposed lines.

AFCA has publicly upheld a 25% landlord premium rise at a Suncorp-owned landlord insurance specialist on the basis of suburb and postcode-level flood risk data (Insurance News, landlord loses complaint over 25% premium hike). AFCA's reasoning was that the insurer had properly calculated the new premium based on data considered at a suburb and postcode level, not on the specific property. The practical read: if your property sits in a postcode whose aggregate loss experience has deteriorated, your premium can move independently of your own claims history.

That is a different complaint environment to the one Australian landlords have operated in for the last decade. Before 2024, the typical landlord renewal dispute was over an insurer-specific pricing error, a misapplied discount, or a misstated sum insured. AFCA upheld plenty of those in favour of the policyholder. The 2026 vintage of landlord disputes is sitting on much harder ground because the underlying driver, postcode-level risk, is defensible to the regulator.

For a landlord, the implication is that the single most effective lever at renewal is shopping across insurers who weight postcode risk differently, not disputing the postcode read with your current insurer. QBE, Terri Scheer, Honey and the big brands all carry different models. A renewal that lands with Suncorp at a 25% increase might land with QBE at 8%. The only way to know is to run quotes side by side with identical sum insured and excess settings.

What the renewal does to a landlord's P&L and tax position#

The cash-flow mechanics on a four-property portfolio in October 2026 look like this.

Start from a $2,640 Canstar benchmark house policy. Overlay the 14.78% Compare the Market capital-city read, cut to 11% once the landlord-specific lines are blended in. That takes the per-property premium to around $2,930. For four properties, the book insurance bill rises from $10,560 to roughly $11,720. The incremental hit is $1,160 across the portfolio, before any postcode adjustment.

Against gross rents, that is a small percentage. Against net cash flow after mortgage, water, rates, strata, management and maintenance, it is often two or three percent of the net annual yield on a geared metropolitan investment. On a $600,000 property returning 3.8% gross and 1.8% net after costs and mortgage, a $300 rise on the policy is roughly 2.8% of annualised net cash flow.

Three tax-side points that matter.

• The ATO treats landlord insurance, building insurance and contents insurance on a rental property as fully deductible rental expenses in the year the premium is incurred (ATO rental expenses). On a 37% marginal rate, a $2,640 landlord premium has an after-tax cost of about $1,663. On the 45% top bracket, the after-tax cost is about $1,452.
• The deduction is annual, not capitalised. It does not get added to your cost base and does not reduce a future capital gains calculation.
• The deduction is unaffected by the 1 July 2027 negative gearing changes on established residential property. Those changes restrict the ability to offset net rental losses against unrelated income, but the operating expenses of a rental property, including insurance, remain deductible against rental income. The after-tax arithmetic above does not change.

For a landlord in the 37% bracket, the real-dollar lift from a $300 premium increase is $189, not $300. On the 45% bracket, the real-dollar lift is $165. The tax shield absorbs about 37% to 45% of the headline rise, which is what makes insurance one of the more forgiving operating-cost lines on a rental P&L even in a year where premiums are up double digits.

The affordability line is lengthening#

The Actuaries Institute's affordability tracking puts the national average home premium up 51% in five years, from $1,940 in 2020 to $2,938 by October 2025 (Actuaries Institute Home Insurance Affordability). On the Institute's measure, around 15% of Australian households, or 1.61 million, now spend more than four weeks of gross income on home insurance. The 14.78% capital-city move in the year to June 2026 extends that line.

For a landlord, the affordability line matters for two reasons.

The first is pricing. The insurer that is pushing a 14.78% capital-city base and a 25% postcode-adjusted top on climate-exposed properties is doing so because the loss experience justifies it. That line is not going backwards. The right planning assumption for 2027 and 2028 is that premium growth continues to run above wage growth, which in the June quarter 2026 printed 3.2% on the Wage Price Index, and above headline CPI, which the RBA's latest Statement on Monetary Policy expects to sit in the mid-3s on trimmed-mean through 2027.

The second is tenant risk. The affordability line also runs through to tenants who hold their own contents insurance. A tenant whose contents premium is up 14.78% in a year is one more squeeze on a household budget already absorbing a 4.60% cash rate and a six-month run of falling consumer sentiment. The practical read is that any insurance-adjacent line in your lease (contents, renters liability, pet damage) is one more place where a tenant may ask for a landlord contribution in 2026-27. The right response, almost always, is a hard no backed by a clean paper trail that the lease was fair at signing.

Three calls a landlord makes before renewal#

The quote-shop call. Before you accept any renewal, run quotes against at least three insurers on identical sum insured, excess and cover lines. The 14.78% Compare the Market read is the floor. The 25% postcode-adjusted top is the ceiling for climate-exposed properties. Where your renewal sits inside that band depends on the insurer's postcode model, your claims history, and your bundling. On a four-property book, a 10% saving across the book is worth $1,000 to $1,200 a year, which pays for a broker review in year one and a renewal review in every year after.

The sum insured reset call. Rebuild cost inflation has outrun headline CPI through 2025 and 2026. Any policy that is renewing with a sum insured for buildings that has been auto-indexed off a 2022 or 2023 base is likely to be underinsured by double digits against current rebuild cost. The right fix is a current quantity-surveyor estimate for anything over $600,000 of building value, and the Insurance Council's online rebuild calculator for anything below that. An underinsured claim is capped at the sum insured, not the actual rebuild, which is the single largest own-goal in a landlord's insurance program.

The timing and tax-year call. For a landlord whose policy anniversary falls in Q4 2026, the premium hits the FY2026-27 tax year. If cash flow allows, prepay the renewal before 30 June 2027 and book the full deduction into the current tax year. For a landlord in the 37% bracket, that pulls forward the $977 tax shield on a $2,640 premium by up to 12 months. Prepayment rules apply to premiums that cover a period of 12 months or less for individual landlords. For landlords holding property via a trust or company, the rules are different and warrant a specific call with your tax agent.

What this does not change#

Insurance is one line in a landlord P&L and the premium rise is a cost, not a trigger for a strategic rethink. Rents are still rising, with Cotality putting national rents up around 5.7% over the year to September 2026. Yields have expanded through the cycle because capital values have fallen faster than rents. Vacancy nationally remains tight. The structural supply shortage has not moved. The policy pipeline (negative gearing changes for new builds from 1 July 2027, foreign-buyer surcharges, the SMSF LRBA ban from 10 August 2026) is unchanged by one insurance renewal round.

What has changed is the operating cost base. The 2026 vintage landlord P&L carries a premium line that is up 10% to 13% blended for the first time in a decade, driven by claims experience and reinsurance pricing that is set offshore. The right posture is to treat insurance as an active cost line, not a set-and-forget one, and to shop every renewal across at least three insurers rather than roll the current carrier for convenience.

Propkt's expense tracking will carry the renewal uplift straight into your annual P&L, flag the deduction against your rental income in the correct tax year, and let you benchmark the per-property premium against the national median by state and property type. The rent management module tracks the policy renewal date against the lease renewal date, which matters because any landlord-insurance change that affects rent default cover should be reflected in the next tenancy renewal correspondence, not left until the claim turns up and the gap is visible.
