Imagine your brand-new car is written off in an accident just months after you drive it out of the dealership. Your insurer pays the market value—but you still owe thousands more on your loan. That’s where gap insurance steps in, covering the difference so you’re not left financially stranded. As more Aussies finance their cars and with new consumer credit reforms in 2025, gap insurance has become a hot topic. But is it really necessary, or just another add-on best skipped?
Gap insurance, sometimes called Guaranteed Asset Protection, is designed to pay the shortfall between your car insurer’s payout and what you still owe on your car loan if your vehicle is declared a total loss. This often happens when:
For example, suppose you buy a new Mazda CX-5 for $50,000 with a $45,000 car loan. Six months later, the car is written off in a flood. Your comprehensive insurer pays $38,000 (current market value), but you still owe $42,000 on your loan. Gap insurance covers the $4,000 difference, so you don’t have to pay it out of pocket.
Gap insurance isn’t for everyone. It’s most relevant if:
On the other hand, if you’ve made a large upfront payment, have a short loan term, or are buying a used car that’s already depreciated, the risk of a loan shortfall is much lower.
The financial watchdog ASIC has tightened regulations on add-on insurance products, including gap insurance, following years of customer complaints and poor value. Here’s what’s changed in 2025:
These changes make gap insurance fairer and easier to understand, but they also highlight the need to shop around—never accept the dealer’s first offer without comparing alternatives from banks, credit unions, or insurers.

Drawbacks:
Before signing up, ask yourself: What’s the maximum I could owe above my car’s value? Is that a risk I can afford to self-insure, or does gap cover make sense?
In 2025, with car prices rising and more Australians taking out longer car loans, negative equity risks are real. Take Sarah, who financed a 2024 Toyota Hilux with a 7-year loan and a $5,000 deposit. When her ute was stolen and written off in January 2025, her insurer paid $44,000—but her loan payout was $48,200. Because she had gap insurance, Sarah avoided a $4,200 bill and walked away debt-free.
