Should You Renew or Switch Car Insurance in Australia?
In a Nutshell: Don't automatically renew your car insurance. Switch every 2–3 years to save the most money. Loyalty is rarely rewarded — new customer discounts are 15–30% below renewal prices. Get a quote from your current insurer (as if you were a new customer) and compare with 2–3 competitors before renewing.
The Loyalty Penalty
| Year with Same Insurer | Average Premium (Same Car, Same Driver) | vs New Customer Price |
|---|---|---|
| New customer | $1,000 | Baseline |
| 1 year | $1,050 | +5% |
| 2 years | $1,100 | +10% |
| 3 years | $1,180 | +18% |
| 5 years | $1,250 | +25% |
| 8+ years | $1,300 | +30% |
💡 Why? Insurers offer introductory discounts to attract new customers. After 12 months, they gradually increase your premium — relying on your inertia to not switch.
The Renewal Process — What to Do
| Step | Action |
|---|---|
| 1 | Don't auto-renew — always review before the renewal date |
| 2 | Check your renewal notice — look for any premium increase |
| 3 | Call your current insurer — ask them to match a cheaper quote from a competitor |
| 4 | Get 3–5 quotes from competitors — use comparison sites and direct insurers |
| 5 | Compare the features — not just the premium. Check excess, hire car, extras |
| 6 | Decide: renew or switch |
| 7 | If switching — ensure the new policy starts the day after the old one ends (no gap) |
| 8 | Provide your NCB — your new insurer needs proof of your no-claim bonus |
When to STAY with Your Current Insurer
| Reason to Stay | Why |
|---|---|
| You have a strong multi-policy discount | Car + home bundle with 15% off — switching one may cost more overall |
| You've had recent claims | A new insurer may charge more because your last claim is recent |
| You have a high NCB protected | If you have no-claim bonus protection, switching resets that protection |
| You're mid-policy | It's usually not worth cancelling mid-policy (cancellation fees, lost premium) |
| Your insurer matches the competitor's price | If they match, staying is easier and avoids admin |
| You love the customer service | Good service has value — especially if you've had a good claims experience |
When to SWITCH
| Reason to Switch | Why |
|---|---|
| Premium increased by 10%+ at renewal | New customer discounts elsewhere will beat this |
| You've been with the same insurer for 3+ years | Loyalty penalty is costing you — switch |
| Your circumstances changed | New car, moved house, added a driver — a fresh quote may find a better deal |
| Better features elsewhere | Another insurer offers more for the same price |
| Negative claims experience | If your insurer treated you badly, it's time to leave |
| Your insurer won't match | They gave you a take-it-or-leave-it price — take it somewhere else |
How Much Can You Save by Switching?
| Scenario | Renewal Price | Switch Price | Saving |
|---|---|---|---|
| Safe driver, been with Insurer A for 5 years | $1,250 | $950 (switching to Insurer B) | $300 (24%) |
| Young driver, 2 years with Insurer C | $2,100 | $1,700 (switch to Insurer D) | $400 (19%) |
| Family, 3 years, multi-policy | $1,150 | $1,050 (switch — but check multi-policy impact) | $100 (9%) |
💡 Average saving from switching: $200–$400 per year — about 15–25% off your premium.
The Art of Negotiation — How to Get Your Current Insurer to Match
| Script | What to Say |
|---|---|
| "I've received a lower quote from [competitor] for $X. Can you match it?" | Most insurers have a retention team that can offer discounts |
| "I've been a loyal customer for X years and I'd like to stay, but the price needs to be competitive." | Loyalty works against you — until you say you're leaving |
| "What can you do to reduce my premium?" | See if they offer discounts you're not currently receiving |
| "Can you waive the monthly payment fees if I stay?" | Small ask — often granted |
⚠️ Be prepared to walk away. If they won't match or come close, switch. The threat of leaving only works if you're actually willing to do it.
The Switching Process
| Step | Action |
|---|---|
| 1 | Buy the new policy (effective from your desired start date) |
| 2 | Provide your NCB details to the new insurer |
| 3 | Cancel the old policy (after the new one starts — avoid a gap) |
| 4 | Get a refund from the old insurer (pro-rata for unused premium, minus admin fee) |
| 5 | Set up payment for the new policy |
| 6 | Confirm cover and check your documents |
⚠️ IMPORTANT: Never cancel your old policy until the new one is active. A gap in cover means no protection — and your NCB may not transfer.
Key Takeaway
- Loyalty is rarely rewarded — switching every 2–3 years saves 15–25%.

- Do NOT auto-renew without checking competitors.
