Australia Is Buying Record Numbers of Cars Right Now. Here's What Three RBA Rate Rises Have Done to Your Loan.

Record Sales. Record Rates. A Dangerous Combination.

July 2026 was the strongest July for new car sales Australia has ever seen. A total of 108,577 new vehicles were delivered last month — up 4.2% on July 2025 — and EVs alone made up more than one in five of every car sold. It is an extraordinary market. But here is the problem nobody at the dealership is talking about: you are signing finance contracts in one of the most expensive rate environments in years.

The cash rate currently sits at 4.35%, having risen 0.75 percentage points across three consecutive RBA moves in February, March, and May 2026. That has fed directly into what lenders charge you. The average car loan rate across all borrower types has climbed to 8.92% p.a. — and one tracker shows the average secured car loan rate rising more than 0.50 percentage points in just six months, hitting its highest point in 2026 as of July. The RBA meets again on 10–11 August. A hold is expected, but it is not guaranteed.

Let that sink in. Australians are buying cars in record numbers at the exact moment borrowing costs have surged. If you are one of those buyers, the finance decision you make right now could haunt your budget for the next five years.

What Three Rate Rises Actually Cost on a Real Australian Car Loan

Let's use real numbers. The average new car loan in Australia is currently $46,055, and the average loan term is five years. Here is what the RBA's 0.75 percentage point hiking cycle has done to that loan — assuming lenders pass the moves through to car loan pricing (which the data shows they largely have):

• At 8.17% p.a. (pre-hike baseline): Monthly repayments ≈ $937. Total interest over 5 years ≈ $10,165.
• At 8.92% p.a. (current average): Monthly repayments ≈ $956. Total interest over 5 years ≈ $11,297.
• Difference: An extra $19 per month — or roughly $1,130 in additional interest over the life of the loan. On a larger loan, that gap blows out fast.

Now factor in that the best rates for prime borrowers range from 6.59% to 9.95% p.a. right now — a spread of over three percentage points. If you are a good borrower but you signed with the first lender you spoke to (usually the dealer's in-house finance), you could easily be sitting at 9.5% when you qualified for 6.9%. On a $46,000 loan over five years, that difference costs you roughly $3,400 in extra interest. That is not a rounding error. That is a holiday.

Why Dealers Love a High-Rate Environment

Here is something ASIC made official in its landmark June 2026 report, which examined data from over 350,000 loans across eight of Australia's largest car finance providers: lenders are not paying enough attention to how dealers and brokers are selling their products — and the consequences for borrowers are real.

The ASIC review found shortcomings in how lenders oversee distributors like brokers and car dealers who sell their loans, directly exposing consumers to harm. In plain English: the dealer sitting across from you has an incentive to put you into a more expensive loan, not a cheaper one. That is not a conspiracy theory. It is a documented finding from Australia's corporate regulator.

In a high-rate environment, this dynamic gets worse. When base rates are elevated, a dealer can justify quoting you a rate that looks "competitive" compared to an even higher benchmark — while still clipping a margin for themselves and the lender. You walk away thinking you got a deal. You didn't.

The Record EV Sales Story Has a Finance Sting in Its Tail

More than one in five cars sold in July was a battery EV — a milestone achieved for three consecutive months now. Australia has purchased 127,244 battery EVs in 2026 alone, already surpassing all of 2025. That is remarkable. But EV finance comes with a specific wrinkle that standard car loan ads never mention: residual value risk.

If you are financing an EV with a GFV (Guaranteed Future Value) loan, a novated lease, or any product with a balloon payment, the lender sets an assumed future value for your car at the end of the term. Here is the uncomfortable truth: some Chinese-brand EVs — and there are now over 90 different Chinese-branded models available in Australia — have experienced faster depreciation as new models flood the market. If the car is worth less than the residual figure when your finance ends, that gap is yours to cover.

The ATO sets minimum residual percentages: 65.63% of the financed amount after one year, 46.88% after three years, and 28.13% after five years. If you financed $60,000 over three years, your minimum residual is around $28,128 — plus GST. If the market only values that car at $24,000 on the day you hand it back, you are personally responsible for the $4,000-plus shortfall. Nobody at the dealership walked you through that scenario when you were excited about the test drive.

The Smart Moves to Make Before 11 August

The RBA announces its next rate decision on Tuesday, 11 August 2026. All four major banks — CBA, NAB, ANZ, and Westpac — are currently forecasting a hold at 4.35%, with June's CPI coming in softer than expected at 3.8% headline. But underlying trimmed-mean inflation is still running at 3.6%, above the RBA's 2–3% target band, and Governor Bullock has not ruled out further hikes. Markets are pricing about a 20–30% chance of an August rise. That is not nothing.

If you are buying a car right now — or about to — here are the moves that actually protect you:

• Get a pre-approval from a bank or credit union before you walk into a dealership. This gives you a real number to compare against whatever the dealer quotes. If they can beat it, great. If they can't, you already have your finance sorted.
• Ask for the comparison rate, not just the headline rate. The comparison rate includes fees and gives you a better read on true cost. A loan advertised at 6.49% can have a comparison rate of 8.20% once establishment fees are loaded in.
• On a GFV or balloon-payment loan, ask the lender to show you what happens if the car is worth 20% less than the guaranteed value. If they refuse or can't answer, walk away.
• Check whether your rate is fixed or variable. Variable-rate car loans generally offer more flexibility and no early repayment penalties — which matters if rates do fall in 2027 as some major banks forecast. Fixed locks you in, for better or worse.
• Consider a shorter loan term if your budget allows. On a $30,000 loan at 7.5% p.a., choosing a three-year term over five years saves around $2,500 in interest. That is real money back in your pocket.

What Milam Does Differently

Most car finance products in this market take your money and give you nothing back when the car leaves your hands. GFV loans hand the car back with nothing to show for it. Standard loans have you paying down interest on a depreciating asset with no upside.

Milam is built on a different idea: lower weekly payments AND an equity payout when you return the vehicle. You are not just servicing debt — you are building a position. In a market where rates are elevated, average loan sizes are hitting $46,000 for new cars, and ASIC has formally warned that borrowers are being overcharged by the very dealers selling them finance, a product that puts money back in your hands at the end is not a gimmick. It is just better maths.

This is not financial advice. Before signing any car finance contract, speak to a licensed financial adviser who can review your full situation.

The Bottom Line

Australia just had its best July for car sales ever. EVs are booming. Chinese brands are reshaping the market. It is an exciting time to buy a car. It is also, objectively, an expensive time to borrow money — and the ASIC data makes clear that the industry is not always working in your favour when it sells you finance. Know your rate. Know your residual. Know what you get back at the end. Everything else is just a shiny brochure.
