How to lower your car insurance in Australia (without losing cover)

A practical guide to lowering car insurance premiums in Australia by adjusting the things that genuinely move the price — without quietly stripping out cover or relying on tricks that can backfire later.

Lowering a car insurance premium is mostly about finding the legitimate levers and pulling them in the right combination. Some adjustments save real money. Others save trivial amounts but add risk. This guide separates the two.

The companion piece to this is our cheap car insurance page, which focuses on the cheapest-overall question. This page is more about optimisation — how to lower what you currently pay without changing the level of cover.

What does "lowering your premium" actually mean?

There are two flavours people often mix up:

• Reducing the price for the same level of cover — usually by switching insurers, lifting the excess, paying annually, or removing extras you don't use.
• Reducing the level of cover — moving from comprehensive to third party, or stripping useful inclusions out. Cheaper, but a different product.

Both are legitimate. The point is to know which one you're doing.

Key things to understand before you adjust

• Insurer-to-insurer differences are usually larger than setting tweaks. Comparing properly often beats fine-tuning a single policy.
• Excess is your biggest single setting lever — see our excess explainer.
• No-claim bonus stacks over time. Protecting it can be more valuable than chasing a small premium cut. See no-claim bonus.
• Loyalty pricing is a real thing. Long-tenured customers don't always get the best renewal price.
• Honest disclosure matters. Saving $100 by under-stating something usually isn't worth the risk of a denied claim later.
• The PDS will tell you what's covered after each adjustment. Worth a quick read after every change.

How to lower your car insurance step by step

1. Compare at renewal. The single highest-impact move for most people. Our compare car insurance page covers the framework.
2. Re-quote with a higher excess. Try $1,000 and $1,500 against your current excess.
3. Strip optional extras you genuinely don't use. Hire car cover is great if you'd actually use it, less so if you wouldn't.
4. Pay annually if cash flow allows. Many insurers add a few percent for monthly payments — covered separately on our pay monthly page.
5. Update circumstance changes. Lower annual kilometres, off-street parking, or removing a regular driver who no longer drives the car can all push the price down.
6. Bundle thoughtfully. Multi-policy discounts can be worth checking, but only when both policies remain competitive.
7. Read the PDS after each tweak to confirm you haven't unintentionally changed cover.

Common mistakes to avoid when chasing a lower price

• Under-stating annual kilometres or business use to reduce the premium. Tempting and dangerous.
• Removing useful extras to save trivial amounts. A $30 saving on hire car cover could become a $500 cost the next time you're off the road.
• Switching insurers for a $40 saving when the hassle and any switching fees swallow the difference.
• Stacking a high excess on top of multiple optional excesses without modelling what you'd actually pay at claim time.
• Forgetting to compare again next year. One round of comparison shopping isn't a permanent saving — pricing models shift.

What affects how much you can realistically lower your premium

• Driver age and experience. Less room to move at very young or very old ends of the curve.
• Recent claims. A recent at-fault claim limits how much premium relief is available short-term.
• Vehicle. A change of car can sometimes do more than any single setting tweak.
• Location. Postcode-level claim history is largely fixed unless you move.
• Claims-free time. Building or protecting a no-claim bonus pays off year on year.
• Insurer mix. Some insurers price aggressively for some profiles and not others. The best car insurance page covers how to think about which insurer may suit which driver.
