Australia Just Had Its Biggest Month of Car Sales Ever. Here's Why That's Dangerous for Your Finance Deal.

The Record Nobody's Talking About

Australia's new car market just smashed every record it's ever set. In June 2026 alone, 140,058 new vehicles were delivered — the highest monthly figure in Australian history, up 9.9 per cent on June 2025. BYD came within 243 sales of toppling Toyota as the nation's top-selling brand. The Tesla Model Y topped the sales charts for the second month in a row. Nearly one in four new vehicles sold was fully electric.

It's a genuinely exciting moment for Australian car buyers. More choice, more competition on price, and more technology than ever before. But here's the thing nobody in the showroom is going to tell you: a booming car market is one of the best environments for a bad finance deal to hide.

Why a Busy Market Hurts Buyers at the Finance Desk

When showrooms are moving record volumes, the pressure shifts. Salespeople have less time per customer. Finance managers are processing more deals. And the detail that gets glossed over — the interest rate, the comparison rate, the hidden fees, the add-on insurance — is exactly the stuff that costs you thousands over the life of a loan.

The numbers are stark. The average car loan interest rate across Australia is currently 8.92% per annum, with average monthly repayments of $710 over five years on a $34,282 loan. The average new car loan sits even higher, at $46,055. Meanwhile, the lowest rate available in the market right now is 5.66% — a gap of more than three percentage points. On a $46,000 loan over five years, that difference adds up to thousands of dollars out of your pocket.

And if you're buying at the dealership and taking whatever finance they put in front of you? There's a real chance you're sitting closer to the 8–9% end of that range, not the 5–6% end.

The Chinese Car Boom Makes This More Complicated

The other big story in that June data: China supplied more than a third of every new vehicle sold in Australia — 46,592 units, or 35.5% of the entire market. BYD, Chery, Haval, Jaecoo, Zeekr, Xpeng — these brands are now mainstream, not niche.

That's great for competition and affordability. But it creates a specific finance problem: many lenders and banks still don't have robust resale data for newer Chinese models. When a lender can't accurately predict what a car will be worth in three to five years, they price that uncertainty into your loan. You may be quoted a higher rate, a lower loan-to-value ratio, or a Guaranteed Future Value figure that's been set conservatively — meaning the lender is protected, but you're not getting the best deal.

If you're buying a BYD, a Chery Tiggo, a Haval Jolion, or any other Chinese brand that's relatively new to Australia, ask your lender directly how they're calculating residual value and whether it affects your rate. Don't assume the finance offer you're getting is the best one available.

ASIC Has Been Watching — and What They've Found Is Ugly

While Australians have been buying cars in record numbers, the regulator has been busy taking the industry to court. Here's what's happened just in 2026 alone:

• Money3 Loans was ordered by the Federal Court to pay $1.55 million in penalties for breaching responsible lending obligations when providing car finance to vulnerable consumers. The court found Money3 failed to properly verify borrowers' living expenses — even though it had access to their bank data.
• Diamond Wheels (Lansvale Motor Group) and Keo Automotive — one of Australia's largest family-owned dealerships — were found by the Federal Court to have provided car loans to consumers without a credit licence and charged unlawful and excessive interest charges. The dealership had been doing this between 2014 and 2024. A penalty hearing is scheduled for 20 August 2026.
• ASIC published a 37-page report on the motor vehicle finance sector after noticing a rise in complaints, finding shortcomings in lender oversight of dealers and brokers selling loans, and putting the industry on notice to lift its standards.

That last point matters. ASIC's position is explicit: responsibility for consumer outcomes cannot be outsourced. Lenders are now on notice that when a dealer or broker sells a dodgy loan on their behalf, the lender wears the consequences. That's good news long-term. But the industry is still catching up — and right now, today, plenty of Australians are still signing contracts without fully understanding what they're agreeing to.

The Rate Gap Nobody Shows You

Here's a number worth sitting with. The average variable car loan rate right now is 8.35%, according to July 2026 data from Finder. But the lowest secured car loan rate available is 5.66%. Green car loans for EVs and plug-in hybrids start even lower, from 5.54%.

If you're buying an EV — and given that nearly one in four new cars sold in June was electric, there's a decent chance you are — you may be eligible for a significantly lower interest rate than a standard loan. Lenders are currently offering an average discount of 1.2% to 1.7% on interest rates for green-eligible vehicles. On a $50,000 loan over five years, that's potentially $2,000–$4,000 in your pocket, not the lender's.

The catch? Most buyers don't know to ask for it. And most dealers have little incentive to tell you, especially if they're earning a commission on the finance product they sell you.

The ATO Numbers Business Owners Need Right Now

If you're buying a car for business use, there's a fresh number to know. From 1 July 2026, the ATO car limit for the 2026–27 financial year is $69,883 — up from $69,674 in 2025–26. This is the maximum value you can use to calculate depreciation on a passenger vehicle used for business purposes. If you buy above that figure, your depreciation claim is capped regardless of what you paid. And the cents-per-kilometre rate has also moved, up to 91 cents per kilometre for 2026–27.

None of this changes the fundamentals — if you're using a vehicle for both business and private purposes, you can only claim the business portion, and you need records to back it up. But it does affect how you structure your finance, and whether the timing of your purchase matters for your tax position. Speak to a financial adviser or accountant before signing — a small timing decision can make a meaningful difference to your tax outcome.

The Five Questions to Ask Before You Sign

With the market moving at record speed, here's a practical checklist to run through before you put pen to paper on any finance contract in 2026:

• What is the comparison rate? Not the headline rate — the comparison rate, which includes fees. If the dealer can't tell you immediately, that's a red flag.
• Is this a green loan rate? If you're buying an EV or PHEV, ask specifically whether you're eligible for a lower rate. Don't assume you're getting it automatically.
• What is the total amount repayable? Add up every dollar — principal, interest, fees, add-on insurance. That's the real cost of the loan.
• Does the lender have a credit licence? It sounds like a basic question, but as the Diamond Wheels case showed, not every entity offering you finance actually has the legal right to do so.
• What happens at the end of the loan? If there's a balloon payment, a Guaranteed Future Value, or a residual — understand exactly what you're on the hook for when the term ends.

The Milam Difference

Most Australians are used to two options at the end of a car finance deal: pay out a balloon payment, or hand the car back and walk away with nothing. Milam is built around a third option — one where you get lower weekly payments AND an equity payout when you return the car, because you've been building equity in the vehicle the whole time, not just paying down someone else's interest margin.

In a record market, with dealers busier than ever and lenders under regulatory scrutiny, the smartest thing you can do is understand exactly what kind of deal you're getting into — and whether it's actually working for you, or just for the finance desk.
