How to Save on Insurance in Australia: Home, Car & Health in 2026
Insurance premiums have surged across Australia. Learn proven strategies to reduce your home, car, and health insurance costs without sacrificing essential cover.
Why Australian insurance premiums have surged
Australian insurance premiums have increased dramatically since 2022, driven by a convergence of factors. Home and contents insurance has risen approximately 16% year-on-year, making it the single largest contributor to CPI inflation. The primary drivers are: increased frequency and severity of natural disasters (the 2022 floods alone cost insurers $7.4 billion), rising global reinsurance costs as climate risks are repriced, higher building material and labour costs pushing up claim values, and supply chain issues extending repair timelines. Car insurance has increased 12–14% due to higher repair costs — modern vehicles with sensors and cameras cost significantly more to fix — and rising theft rates. The ACCC has noted that insurance affordability is now a critical consumer issue, with approximately 1 in 7 Australian homes effectively uninsured or underinsured. Understanding why premiums are rising helps you make informed decisions about where to adjust your cover.
Compare, compare, compare: breaking the loyalty tax
The 'loyalty tax' in insurance is well-documented: insurers offer their best prices to new customers while gradually increasing premiums for existing policyholders. ASIC research found that loyal home insurance customers paid 27% more on average than new customers with the same risk profile. The fix is simple but requires annual effort: get at least three quotes every renewal. Use comparison sites like Compare the Market, iSelect, and Canstar, but also go direct to insurers not listed on comparison sites (RACV, NRMA, Budget Direct, and Youi often do not appear). When you receive your renewal notice, call your current insurer and tell them you have a cheaper quote — retention teams often have authority to match or beat competitor prices. This single habit of comparing annually can save $300–$800 on home insurance and $200–$500 on car insurance each year. Set a calendar reminder 3–4 weeks before each policy renewal date.
Excess strategies to lower your premiums
Your excess (the amount you pay when making a claim) has a significant inverse relationship with your premium. Increasing your home insurance excess from $500 to $1,000 typically reduces premiums by 15–25%. Increasing car insurance excess from $600 to $1,200 can save 10–20% on annual premiums. The strategy works if you can afford to cover the higher excess from savings in the event of a claim, and if you rarely claim. Statistically, most policyholders make a home insurance claim only once every 8–12 years, so the cumulative premium savings usually far exceed the one-time higher excess payment. For car insurance, consider your vehicle's value: if your car is worth $8,000, a $2,000 excess might not make sense as the insurer would only pay $6,000 on a total loss. For home insurance, ensure your excess is comfortable but meaningful — $1,000–$2,000 is the sweet spot for most households.
Bundling discounts and other savings tactics
Most major insurers offer multi-policy discounts of 5–15% when you bundle home, contents, car, and landlord insurance with the same provider. Suncorp, AAMI, Allianz, and QBE all offer bundling discounts. However, always check that the bundled price is genuinely cheaper than the best individual prices from different insurers — sometimes the cheapest individual policies from separate companies still beat a bundled deal. Other proven savings tactics: pay annually rather than monthly (monthly payments typically include a 10–15% loading), install security devices (alarm systems can reduce home premiums by 5–10%), increase home security with deadlocks and window locks, and for car insurance, limit named drivers to exclude high-risk drivers under 25. Paying by direct debit to avoid credit card surcharges saves another 1–2%. These small changes compound: a combination of comparison shopping, higher excess, annual payment, and bundling can reduce total insurance costs by 30–40%.
Health insurance: understanding the rebate tiers
The Australian Government Private Health Insurance Rebate reduces your premium based on your age and income. For singles earning under $97,000 (or families under $194,000), the rebate is approximately 24.6% for those under 65. The rebate drops to 16.4% for singles earning $97,001–$113,000, then 8.2% for $113,001–$151,000, and zero above $151,000. If you earn above $97,000 as a single (or $194,000 as a family) and do not hold hospital cover, you pay the Medicare Levy Surcharge (MLS) of 1–1.5% of taxable income — this is effectively a tax penalty for not having private hospital cover. For a single earner on $120,000, the MLS would cost $1,200–$1,800 per year, which often exceeds the cost of a basic hospital policy. Running the numbers to determine whether holding basic hospital cover saves you money via MLS avoidance is one of the most overlooked tax planning strategies in Australia.
Reducing health insurance costs without losing value
The most effective way to cut health insurance costs is to match your cover level to your actual usage. If you are a healthy 30-something who only needs hospital cover for MLS purposes, choose a Basic or Bronze tier hospital policy with a $750 excess — premiums can be as low as $90–$130 per month. Drop extras cover if you are not regularly using dental, optical, or physio — many people pay $50–$80 per month in extras premiums but only claim $300–$500 per year. If you do use extras, check that your annual claims exceed your annual extras premium, otherwise you are losing money. Consider health fund alternatives for extras: a dental plan through a provider like National Dental Care ($25/month for two check-ups) may be cheaper than full extras cover. Review your policy annually using privatehealth.gov.au — the government's official comparison tool that lists every policy from every fund with standardised benefit descriptions.
Green slip and CTP insurance savings
Compulsory Third Party (CTP) insurance — called a green slip in NSW — is required for all registered vehicles and costs vary significantly between providers. In NSW, the State Insurance Regulatory Authority's Green Slip Price Check (greenslips.nsw.gov.au) lets you compare prices across all licensed CTP insurers. Price differences of $50–$150 for identical cover are common. In Queensland, CTP is included in registration costs with no choice of provider, but in NSW, Victoria (TAC levy), South Australia, and the ACT, shopping around can save money. For NSW drivers, the cheapest green slip providers are typically QBE, NRMA, or GIO depending on your vehicle type, age, and location. Business-use vehicles pay significantly more than private use — if you have changed from business to personal use, update your CTP to save $100–$200 immediately. At-fault claims can increase CTP costs at renewal, so maintaining a clean driving record has a direct financial benefit.
