Your rights in 60 seconds

• The Australian Consumer Law (ACL) always applies to a car bought from a dealer, new or used, of any age: it must be of acceptable quality for its price, age and kilometres.
• Major failure: refund or replacement, your choice (ACL ss 259(3), 263(4)). The dealer cannot force a repair on you.
• Minor failure: the dealer must fix it within a reasonable time, or you can have it fixed elsewhere at its cost or reject the car (s 259(2)).
• The NT adds a dealer’s duty to repair (Consumer Affairs and Fair Trading Act 1990 s 168): for a used car sold no more than 10 years after manufacture with under 160,000km, defects that appear within 3 months of you taking possession or 5,000km after the sale, whichever comes first. Motorcycles qualify up to 5 years and 30,000km. New cars and demonstrators are covered too. It sits on top of the ACL: when it ends, your ACL rights do not.
• There is no cooling-off period for any car purchase in the NT.
• NTCAT hears claims up to $25,000. From $25,000 to $250,000 the claim must go to the Local Court.

Which state’s law applies to you

It is the location of the dealer that sold you the car that counts, not where you live. If the dealer is in the Northern Territory, the NT dealer’s duty to repair, NT Consumer Affairs and NTCAT (or the Local Court) are the ones that apply, even if you live in Queensland or bought online and had the car shipped to you. If the dealer is in a state, read that state’s page: the NT duty will not apply, even if you live in Darwin or Alice Springs. The ACL applies either way.

The interstate rule. Burns v Corbett [2018] HCA 15 stops state tribunals that are not courts, such as the NSW and Victorian tribunals, from deciding disputes between an individual or sole-trader dealer and a buyer who lives in a different state. It does not limit NTCAT on an NT dealer claim: the rule is about residents of different states, and NTCAT is a territory tribunal. An NT dealer claim stays in NTCAT (up to $25,000) or the Local Court (above $25,000) wherever you live.

NT Consumer Affairs helps interstate buyers. Its conciliation service is normally for NT residents, but it accepts disputes about a motor vehicle bought in the NT even if you live elsewhere.

Your rights under the Australian Consumer Law

The ACL (Schedule 2 to the Competition and Consumer Act 2010 (Cth)) applies in the Northern Territory exactly as it does everywhere else, and the NT dealer law says nothing in s 168 “derogates from” the ACL acceptable quality and fitness guarantees (CAFTA s 168(6)(b)). You are a “consumer” if the car cost $100,000 or less, or is a kind of vehicle ordinarily bought for personal or household use, so a family car is covered even above $100,000 (ACL s 3(1); Competition and Consumer Regulations reg 77A).

Acceptable quality (s 54)

The car must be fit for all its usual purposes, acceptable in appearance and finish, free from defects, safe and durable, as a reasonable consumer who knew its full condition (including hidden defects) would regard as acceptable. That is judged against the nature of the car, the price, anything the dealer or manufacturer said about it, and other circumstances such as age and kilometres. An old, cheap car need not be perfect, but it must run, be safe and last a reasonable time for what you paid.

The guarantee does not cover faults the dealer specifically pointed out before you agreed to buy (s 54(4)), faults your own inspection ought to have revealed (s 54(7)), or damage from abnormal use (s 54(6)). The car must also match its description, such as the model, year or service history advertised (s 56), and be fit for any purpose you told the dealer about, such as towing (s 55).

What is a major failure (s 260)

A failure is major if any of these apply:

• a reasonable consumer fully aware of the problem would not have bought the car;
• the car departs in a significant way from its description;
• it is substantially unfit for its normal purpose, or for a purpose you made known, and cannot be fixed easily and within a reasonable time; or
• it is unsafe.

Several minor faults can add up to a major failure. For contracts made on or after 18 December 2020, two or more failures, related or not, are a major failure if a reasonable consumer aware of them taken as a whole would not have bought the car (s 260(2)). The ACCC’s industry guide adds that repeated repairs that keep a car off the road for unreasonable periods are likely to be a major failure.

Refund or replacement is your choice (ss 259(3), 263(4))

For a major failure you can reject the car, and the dealer must act “in accordance with an election made by the consumer”: refund what you paid plus the value of any trade-in, or replace the car with one of the same type and similar value if one is reasonably available. A credit note is not a refund (s 263(5)), and the ACCC says a refund for a major problem should be the full amount you paid (ACL s 263(4)). If the car cannot be returned without significant cost to you, the dealer must collect it at its own expense (s 263(3)). Instead of rejecting, you can keep the car and claim its drop in value.

The rejection period (s 262)

You must reject within the time in which it would be reasonable to expect the fault to show up, considering the type of car, its likely use, how long it should last and how much use is reasonable. The Act sets no fixed number of days or kilometres, and the ACCC says the period can run past a warranty. Reject in writing as soon as you know the fault is major.

Damages, “sold as is” and the manufacturer

• Extra losses that were reasonably foreseeable, such as towing, inspection, a hire car or wasted registration, are recoverable (s 259(4)).
• “Sold as is” or “no refunds” does not remove the guarantees. A term that tries to is void (s 64).
• The dealer cannot send you to the manufacturer. The ACCC says the dealer “must not tell the consumer to go to the manufacturer for a remedy”; the dealer recovers its own costs from the manufacturer (s 274).
• The manufacturer owes damages only: the drop in value and foreseeable losses (ss 271-272), claimed within 3 years of when you first became aware, or ought reasonably to have become aware, of the failure (s 273). A refund or replacement comes from the dealer.
• Misleading you about your rights is penalised. Refusing a remedy is not yet a penalty offence (reforms are announced, not passed), but misleading you about your rights is: in February 2024 the Federal Court ordered Mazda Australia to pay $11.5 million in penalties for misleading 9 consumers.

If the car is on finance

• A dealer-arranged lender is jointly liable with the dealer for consumer guarantee failures if it is a “linked credit provider” (ACL s 278), up to the amount financed plus interest and costs (s 281).
• Rejecting the car can end the loan. If the sale is rescinded, you can end a tied loan from the dealer’s linked lender and recover interest you paid (National Credit Code s 135). Tell the dealer and the lender in writing.
• Keep paying while a minor fault is fixed, as the ACCC advises. If you cannot pay, give the lender a hardship notice, orally or in writing; it must answer in writing within set times (NCC s 72).

The NT dealer’s duty to repair (statutory warranty)

The NT rule is in Part 10 of the Consumer Affairs and Fair Trading Act 1990 (NT) (CAFTA), Division 5, Subdivision C, ss 168-171, headed “Obligation of dealer to repair certain defects”. The dealer must, at its own expense, “repair and make good the defect … so as to place the vehicle in a reasonable condition having regard to its age and the distance it has travelled” (s 168(3)). It covers defects that existed, or were potentially there, at the time of sale and later appear (s 168(1)(a)). The duty is treated as an express term of your contract of sale (s 168(4)).

The exclusion form does not remove your ACL rights. NT Consumer Affairs calls the waiver form “Notice to purchaser: Sale excluding statutory warranties”, and nt.gov.au calls it “form 12”. It can only exclude the s 168 repair duty. The prescribed warning itself tells you that you can still expect the car to be fit for its purpose, and the ACL guarantees cannot be signed away (ACL s 64).

Two more NT protections. It is a condition of every dealer sale that the car is of a standard fit to meet registration requirements under the Motor Vehicles Act 1949, unless it was sold for wrecking or under an approved-form contract excluding that condition (s 165). And a dealer’s contract for a second-hand car must be in writing in the approved form; if it is not, you can rescind by written notice within 3 months of the contract date, with each side giving back what it received (s 160).

Cooling-off in the Northern Territory

There is no cooling-off period for vehicle purchases in the NT, new or used. NT Consumer Affairs states this in capitals in its used-vehicle fact sheet, and nt.gov.au repeats it. There is no right to change your mind after you sign. Your exits are the ones on this page: a fault that gives you rights under the ACL or s 168, or (for a used car) a contract that was not in the approved written form (s 160). Read the contract and inspect the car before you sign.

Compensation fund

None. The NT dealer law (CAFTA, as in force at 28 August 2026) has no claim, fidelity or compensation fund for people who buy from motor dealers, and NT Consumer Affairs’ motor vehicle pages mention none. Your remedies are against the dealer itself, and against a dealer-arranged lender where ACL s 278 applies.

New cars in the Northern Territory

Unlike most states, the NT has its own rule for new cars. Under s 168 Case 1, the selling dealer must repair defects in a new or demonstrator car that appear while the manufacturer’s warranty is still running, or within 3 months or 5,000km if there is no manufacturer’s warranty. That duty passes to later owners until a dealer acquires the car or a financier repossesses it (s 171(2)-(3)).

This is on top of the ACL guarantees and the manufacturer’s warranty. The ACL guarantees are not limited to the manufacturer’s warranty period and can continue after it ends. There is no cooling-off period for new cars.

Private sales and auctions

• Private sales: the s 168 duty binds only a dealer. NT Consumer Affairs says that when buying privately “you will not have the benefit of a statutory warranty or consumer guarantees”, and recommends a PPSR check. But someone who sells 4 or more cars in 12 months is presumed to be a dealer (s 126(1)), so a “private” seller with a yard full of cars may owe you the dealer duty.
• Auctions: sales by a licensed auctioneer at auction are excluded from s 168 (s 169(3)(e)). The ACCC says most consumer guarantees do not apply to second-hand cars bought at auction.
• Online marketplaces: the ACL auction exclusion covers auctions run by the seller’s agent. The ACCC’s industry guide says eBay auctions are not “sales by auction” for this purpose, because eBay is not the seller’s agent.

Evidence checklist

1. The contract (check it is on the approved form) and the tax invoice, with the dealer’s registered company name.
2. Any exclusion form you were asked to sign, and where and in front of whom you signed it.
3. The advertisement or listing (screenshot it now, before it disappears).
4. Photos of the odometer on the day of sale and today, and the build or certificate plate date.
5. Dated photos and videos of each fault, including warning lights and noises.
6. Your written description of the defect to the dealer and proof of when you sent it.
7. The dates the car was with the dealer for checks or repairs (they pause the 3-month clock).
8. An independent mechanic’s report or quote, ideally saying whether the fault was likely present at sale.
9. Every message with the dealer: texts, emails and notes of calls (date, time, who, what was said).
10. Receipts for towing, inspection, hire cars and repairs you paid for.
11. Your finance contract, if the dealer arranged the loan.
12. Your NT Consumer Affairs conciliation reference number.

The 5 steps to a refund, replacement or repair

Step 1: Contact the dealer

Phone the dealer and describe the fault, then email the same description that day so there is a written record. Give them 24 hours to respond, and note every call (date, time, who, what was said). The NT law sets no deadline for a written defect notice, but the defect must appear within the s 168 period, so tell the dealer as soon as it shows up and keep proof of the date.

Step 2: No response or a refusal: send a formal demand

If the dealer ignores you, refuses, blames the manufacturer or offers less than you are entitled to, send a formal demand. Ours sets out the ACL and the NT dealer’s duty to repair, lists the defects, states your choice of refund, replacement or repair, and asks for a written response by a firm deadline.

Send the dealer a formal demand – $49

Step 3: Complain to NT Consumer Affairs

Apply to NT Consumer Affairs for conciliation and attach a copy of your demand letter to show you tried. This matters in the NT: its conciliation service only takes a dispute if you have written to the business asking for a written response within 7 to 10 business days. Your letter is that proof; let its deadline pass first.

The other conditions: the goods or services are worth $75 or more; you live in the NT, or the dispute is about a motor vehicle bought in the NT; there may be a consumer guarantee failure; if you paid by credit card, a chargeback has been tried; no legal action has started; both you and the dealer are willing to take part; and the dealer is not in liquidation. So apply before you lodge with NTCAT. The service is free, informal, voluntary and confidential. NT Consumer Affairs tells you within 10 business days whether it has accepted your request, but “can’t force anyone to accept an outcome”. It is not compulsory before NTCAT.

Step 4: Send the final demand

When NT Consumer Affairs gives you a reference number, send a final demand quoting your first letter, the dealer’s response (or silence) and that number, with a short final deadline before NTCAT or the Local Court.

Send the final demand – $49

Step 5: Apply to NTCAT (or the Local Court above $25,000)

For claims up to $25,000, file a Form 1 Initiating Application with NTCAT, naming the dealer by its registered company name, not its trading name. For $25,000 to $250,000, the claim must go to the Local Court. Then follow the process; the tribunal or court decides the outcome.

Prepare your tribunal application – $97

Where your claim goes

NTCAT small claims fees in full from 1 July 2026: for an individual, under $2,000 $129; $2,000 to $10,000 $259; over $10,000 $518. For a body corporate, $160, $324 and $648. Fee waivers are available for hardship (Form 8).

No special car process. Unlike Queensland, the NT dealer law has no dedicated tribunal procedure for car claims; they go through NTCAT’s ordinary small claims jurisdiction under the Small Claims Act 2016 (NT). That Act has no provision letting you give up the amount over $25,000 to stay in NTCAT, so value your claim carefully before choosing the forum.

How to apply to NTCAT. Complete the Form 1 Initiating Application. Contacts: email AGD.ntcat@nt.gov.au; phone 1800 604 622 or (08) 8944 8720. Casuarina Registry: The Met Building, Level 1, 13-17 Scaturchio Street, Casuarina NT 0811 (post: PO Box 41860, Casuarina NT 0810). Alice Springs Registry: Westpoint Building, 1 Stott Terrace.

After you win: getting paid

NTCAT does not enforce its final orders. If the dealer does not pay, you register the NTCAT order with the Local Court. Once registered, it is taken to be an order of the Local Court and can be enforced like one. Not complying with an NTCAT order is also an offence.

Step 1: register the NTCAT order

File a copy of the monetary order certified by the NTCAT Registrar as a true copy, and your affidavit about the amount not paid (NTCAT Act s 84). No fee is payable for filing the order or the affidavit. If the Local Court decided your claim (claims over $25,000), you already have a Local Court order.

Step 2: choose how to enforce it

The Local Court can enforce a money order by a warrant of seizure and sale, an attachment of earnings order, an attachment of debts order, a charging order, appointing a receiver, sequestration, or any combination of those.

• Bank account or money owed to the dealer: for a garnishee (attachment of debts) order, apply to the registrar of the court where the judgment was made.
• Wages: under an attachment of earnings order, the court decides the amount, making sure the debtor keeps enough for living expenses. This is called the protected earnings rate. An employer must not dismiss or disadvantage an employee because of the order.
• Property: under a warrant of seizure and sale, a bailiff takes and sells goods the debtor fully owns. The debtor keeps essentials such as clothing and tools of trade. The warrant stays in force for 12 months.

Finding out what they own: examination summons

The court can issue an examination summons. The debtor must attend and give details of their weekly costs and a payment plan. If they do not attend, the court can adjourn or issue a warrant for their arrest. A debtor cannot be fined, imprisoned or arrested just for not paying a debt.

Local Court fees as at 1 July 2026.

Questions people ask

Is there a lemon law in the Northern Territory?

No, there is no separate lemon-law Act in the Northern Territory. Your protection comes from the Australian Consumer Law, which gives a refund or replacement for a major failure, plus the dealer’s duty to repair in section 168 of the Consumer Affairs and Fair Trading Act 1990 (NT), which covers many used cars and also new and demonstrator cars.

Can I return a used car to a dealer in the Northern Territory?

Yes, if the car has a major failure you can reject it and choose a refund or a replacement under the Australian Consumer Law. There is no cooling-off period in the NT, so you cannot return a car just because you changed your mind. For a minor fault, the dealer can choose to repair it.

What is a major failure for a car?

A major failure is a fault so serious that a reasonable buyer who knew about it would not have bought the car. It also covers a car that is unsafe, departs significantly from its description, or cannot easily be made fit for normal use. For contracts from 18 December 2020, several minor faults together can be a major failure.

Does the Australian Consumer Law apply to second-hand cars?

Yes, the Australian Consumer Law applies to second-hand cars bought from a dealer, whatever their age or kilometres. The car must be of acceptable quality for its price, age and condition. Most consumer guarantees do not apply to private sales or auctions. The NT dealer’s duty to repair applies on top of the ACL for qualifying cars.

I live in another state – which tribunal do I use?

Use the forum where the dealer is: for an NT dealer that is NTCAT for claims up to $25,000 and the Local Court above that, wherever you live. The Burns v Corbett limit on tribunals hearing disputes between residents of different states affects some state tribunals that are not courts, such as the NSW and Victorian tribunals; it does not affect NTCAT. NT Consumer Affairs also conciliates disputes about cars bought in the NT for non-residents.

How long do I have to reject a faulty car?

You must reject within a reasonable time, called the rejection period, which depends on the type of car, its likely use and how long it should last. There is no fixed number of days, and it can run past any warranty. The NT dealer’s duty to repair covers used-car defects appearing within 3 months or 5,000km.

Can the dealer refuse a refund and only offer repairs?

Not for a major failure: then you choose between a refund and a replacement, and the dealer cannot insist on a repair. For a minor failure the dealer may choose to repair, replace or refund, but must fix it within a reasonable time. Your ACL rights do not end when a statutory warranty expires.

What does it cost to go to NTCAT?

An NTCAT small claim costs an individual $129 for a claim under $2,000, $259 for $2,000 to $10,000, and $518 for over $10,000 (fees from 1 July 2026). Companies pay $160, $324 or $648. Fee waivers are available for hardship. Claims over $25,000 go to the Local Court, where a Statement of Claim costs $648.

What if the car was on finance?

If the dealer arranged the loan through a lender it works with, that lender is jointly liable with the dealer for consumer guarantee failures, up to the amount financed plus interest and costs (ACL ss 278, 281). If the sale ends, for example because you rejected the car, the National Credit Code usually lets you end a tied personal loan from a linked lender and recover interest you paid (s 135), unless you approached the lender yourself. Tell both the dealer and the lender.

Can I get my money if I win and the dealer still won’t pay?

Yes, there are legal ways to enforce an order the dealer ignores; see “After you win: getting paid” above. If the dealer arranged your finance, the lender is jointly liable, and a judgment can be enforced against the lender once a written demand on the dealer has gone unpaid for 30 days (ACL s 283). The NT has no dealer compensation fund to claim from.

Is there a cooling-off period for cars in the NT?

No, there is no cooling-off period for any vehicle purchase in the Northern Territory, new or used. You cannot cancel just because you changed your mind. You can still rely on the Australian Consumer Law and the dealer’s duty to repair if the car is faulty, and for a used car you can rescind within 3 months if the dealer did not use the approved written contract.

The dealer asked me to sign a form excluding the warranty. What does that mean?

It excludes only the NT dealer’s duty to repair, and only if signed away from the dealer’s premises in front of a nominated person or police officer who read you the prescribed warning first. Any other exclusion is void. The form cannot remove your Australian Consumer Law rights, which no contract can sign away (ACL s 64).
