Mechanic Botched the Repair? How to Get Your Money Back (Australia 2026)

Last updated 27 October 2026 · Reviewed by the Claim Done team · Not legal advice

Can you get your money back from a mechanic?

You can, if the repair or service failed one of the consumer guarantees for services. These guarantees apply automatically whenever a business repairs your car, whether that’s a dealership service department, an independent mechanic, a tyre and brake shop, an auto electrician or a panel beater. They are set out in the Australian Consumer Law (ACL):

• Due care and skill (s 60). The work has to be done with the care and skill a competent repairer would use. Fitting the wrong part, leaving bolts loose, damaging something else while working, or misdiagnosing a fault through carelessness can all fail this guarantee.
• Fit for the purpose you made known (s 61). If you said “the car overheats on the highway, fix that”, the repair has to be reasonably fit to achieve that result, unless you didn’t rely on the mechanic’s skill (for example, you insisted on a particular repair against their advice).
• A reasonable time (s 62). If no completion date was agreed, the job must be finished within a reasonable time. A car left sitting for weeks with no work done can fail this guarantee.

What you get depends on how serious the failure is. For a minor failure, you can require the workshop to fix it within a reasonable time, at no charge. If it refuses, or takes too long, you can have another repairer fix it and recover the reasonable cost, or cancel the contract (s 267(2)). For a major failure, you can cancel and claim a refund for the work you paid for but didn’t get the benefit of, or keep the work and claim the drop in its value (s 267(3)). A failure is major if a reasonable person who knew about it wouldn’t have paid for the service, if it can’t easily be put right, or if the repair “creates an unsafe situation” (s 268). A brake, steering or wheel job done badly can fall into that last group. On top of either remedy, you can claim damages for any loss that was reasonably foreseeable, such as towing, a hire car or damage to other parts (s 267(4)).

A workshop can’t contract out of this. Any term on a job card, quote or invoice that tries to exclude or limit the guarantees is void (s 64). “We take no responsibility for customer cars” and “all repairs final” have no legal effect against these rights.

One honest limit: the guarantees don’t cover a fault the repairer had nothing to do with. If you diagnosed the problem yourself and asked for one specific repair that didn’t cure it, WA Consumer Protection says the repairer isn’t liable for that. The ACCC also says there’s no remedy where you asked for a job to be done a certain way against the business’s advice.

If the car itself was faulty when you bought it from a dealer, that’s a different claim against the dealer, with its own state warranty rules. See our guide to lemon laws in Australia.

The most common problems with mechanics and panel beaters

1. The fault came straight back. You paid to fix a noise, leak or warning light and it returned within days. Claim: a free re-do, or the reasonable cost of another workshop fixing it properly (s 267(2)).
2. The repair caused a new problem. An oil leak after a service, a coolant hose not reconnected, a wheel not torqued. Claim: the cost of fixing the new damage and any foreseeable loss, such as towing (s 267(4)).
3. Work you never approved. You booked a service and got a bill for brake discs and a timing belt. NSW Fair Trading says work must be limited to what you authorised, and WA Consumer Protection says you authorise work “based on the original quote and any agreed additional work”. Claim: you dispute paying for the extra work.
4. Bill well over the quote. NSW Fair Trading says a price agreed before the work starts is generally binding. Claim: the difference between the agreed quote and what you were charged. Our Overcharge and Invoice Dispute letter is built for this.
5. Damage while the car was in their care. Scratches, a dented panel, a cracked windscreen, a kerbed wheel, or a car damaged while being test driven. Claim: the cost of repair, as loss caused by a failure of due care and skill.
6. Panel beating that doesn’t match. Paint that doesn’t match, panels with uneven gaps, rust coming through within months. Claim: a re-do, or another panel beater’s quote to put it right.
7. The car held for weeks. No parts ordered, no updates, no work done. Claim: cancel, collect the car and recover money paid for work not done, plus foreseeable costs such as transport (ss 62, 267, 269).
8. Second-hand or refurbished parts charged as new. NSW Fair Trading says reconditioned or exchange parts should be noted on the invoice. If refurbished parts may be used, the ACL requires a written repair notice before the car is accepted for repair (s 103). Claim: the price difference, and a misleading-conduct point in your letter.
9. “Your warranty is void because you serviced elsewhere.” Usually wrong. The ACCC says servicing at an independent repairer doesn’t affect your consumer guarantee rights, and saying otherwise may be misleading. WA Consumer Protection says independent licensed mechanics can service your car without voiding the manufacturer’s warranty, as long as the work and parts meet the manufacturer’s standards.

Repairer licensing, quotes, liens and compensation funds

Licensing (NSW and WA)

In New South Wales, repairers must have a licence and use certified tradespeople for any repair that affects a vehicle’s safety or performance. Businesses that only fit accessories that don’t affect safety or performance don’t need a licence, but still have consumer law obligations. You can check a repairer on NSW Fair Trading’s public register. In Western Australia, repair businesses must be licensed under the Motor Vehicle Repairers Act 2003 and must employ qualified supervising staff. Only licensed businesses can display the yellow and black licensed-repairer tick sign. An unlicensed operator is worth reporting, and licensing also matters for the compensation funds below.

Quotes, extra work and diagnosis fees

NSW Fair Trading’s guidance is the clearest statement of the rules most workshops work to:

• Get a written quote that covers parts and labour.
• Tell the repairer whether to go ahead with any further necessary repairs, or to call you first. Work must be limited to what you authorised.
• A workshop can charge a diagnostic fee, and you have to pay it even if you then decline the repair. So check what diagnosis will cost before you agree.
• Ask for the repair warranty to be written on the invoice, and ask to see the parts that were replaced.
• Repair prices aren’t controlled, but NSW Fair Trading can look into a complaint about a fair cost. A quote you agreed to is generally binding on the workshop.

Under the ACL you can also ask for an itemised bill within 30 days of the job or the bill, whichever is later. It must show how the price was worked out, the labour hours and hourly rate, and the materials and what each cost. The workshop must provide it within 7 days, free of charge (s 101). This is often the fastest way to expose padded labour or parts you never got.

When the workshop keeps your car

If you don’t pay, a repairer can usually keep the car until the bill is paid. NSW Fair Trading calls this a mechanics or repairers lien, and says that police can’t order the car’s release, although a court can. WA Consumer Protection says a repairer is entitled to be paid in full before releasing the car unless you’ve agreed otherwise. Practical point: NSW Fair Trading also says that paying the bill doesn’t stop you lodging a dispute. If you need the car back, pay, tell the workshop in writing on the same day that you dispute the amount and why, and then claim it back with the steps below.

Insurance repairs

If your insurer chose or approved the panel beater, check your policy: it may require a repairer from the insurer’s network. A dispute with the insurer itself about the claim goes to AFCA, the free financial complaints body (WA Consumer Protection points car-insurance disputes there). Our Insurance Complaint letter covers that route. A claim about the quality of the panel beater’s work still lies against the business that did the work.

Compensation funds for bad repairs

• NSW: Motor Dealers and Repairers Compensation Fund. It can pay for loss from repair work by a licensed repairer or tradesperson that wasn’t competently done. It’s a last resort: you must first take reasonable steps to use your legal remedies, which can include going to NCAT and trying to enforce the order. Claim within 18 months of the loss or of becoming aware of it. The maximum payment is $100,000.
• WA: Motor Vehicle Repairers Act 2003 compensation fund. Owners who lost money through incompetent repair work by a licensed repairer, or incomplete work because a licensed repairer went insolvent, can claim, but only after trying to resolve the matter.

What you can claim from a mechanic

• A free re-do of work that wasn’t done properly (minor failure).
• The cost of another repairer fixing it, if the original workshop refuses, stalls, or you’ve lost confidence after it failed to fix it within a reasonable time. Get at least one written quote or invoice from the second repairer.
• A refund of what you paid for work that failed badly (major failure), less a reasonable amount for any part of the work that was done properly and was of use to you.
• Money you were overcharged: unauthorised work, charges above an agreed quote, parts not fitted.
• Damage to the car caused while it was with them, at the cost of a proper repair.
• Foreseeable loss: towing, a hire car or taxis while the car was off the road because of the bad repair, a second diagnosis fee, and damage the failed repair caused to other parts.

Work the amount out from documents, not feelings. Add up the invoice for the failed work (or the part of it that failed), the second repairer’s invoice or quote, and receipts for foreseeable costs. Leave out anything that would have been needed anyway, such as normal wear items that were due.

Example (round numbers, for illustration only): you paid a workshop $1,200 to replace a clutch. Two weeks later the clutch slips. The workshop says it’s “driver error” and refuses to look at it. Another licensed workshop finds the wrong part was fitted and charges $900 to fix it properly. You also paid $150 for a tow. A reasonable claim against the first workshop is $1,050: the $900 to have the failure remedied elsewhere (s 267(2)) plus $150 foreseeable towing cost (s 267(4)). You don’t also claim the original $1,200, because you now have a working clutch.

Evidence to gather

1. The quote, booking confirmation or job card, and any message where you approved (or didn’t approve) extra work.
2. The invoice and proof of payment (card statement, receipt).
3. An itemised bill, requested in writing under ACL s 101 if the invoice is vague.
4. Photos and video of the problem, with dates: dashboard warning lights, leaks under the car, damage to panels or wheels. If the car was damaged in their care, photos from before you dropped it off help a great deal.
5. The odometer reading when you dropped the car off and when you collected it.
6. A written report or invoice from a second licensed repairer saying what was wrong and what caused it. This is often the single most persuasive document at a tribunal.
7. The replaced parts, if you can get them back (ask for them before the job starts).
8. Receipts for towing, hire cars, taxis and any second diagnosis.
9. Every email, text and call note with the workshop, including dates and names of who you spoke to.
10. The workshop’s legal business name and ABN, from the invoice or the ABN Lookup.

How to get your money back: 5 steps

Step 1: Tell the workshop in writing what went wrong and what you want

Ring first if you like, but follow up in writing the same day. Say what work was done and when, what went wrong, and exactly what you want: the job redone free, a refund of $X, or payment of another repairer’s invoice. Attach photos. Give a short deadline, such as 5 business days, and keep a copy. If the failure is minor, offering the workshop the chance to fix it first strengthens your position later. For problems with other kinds of business, see our get your money back hub.

Step 2: No answer, a refusal or a runaround? Send a formal demand

Our Consumer Guarantee Letter sets out the services guarantees (ss 60-62), the remedies in s 267, the amount and a 14-day deadline. It’s the kind of letter a tribunal expects to see before you file. Workshops that ignored a phone call often respond to a properly framed demand. If your dispute is purely about being charged more than you agreed, use the Overcharge and Invoice Dispute letter ($49) instead. The general Letter of Demand ($49) is a fallback for anything else.

Send a Consumer Guarantee Letter – $49

Step 3: Complain to Fair Trading in the workshop’s state

Lodge a complaint with the consumer regulator in the state where the workshop is, and attach your letter. These services are free and can get a stubborn business to the table, but none of them can order the workshop to pay you. In NSW and WA, where repairers are licensed, the regulator is also the licensing body.

• NSW: NSW Fair Trading, 13 32 20, online complaint form. Its vehicle dispute service is voluntary.
• VIC: Consumer Affairs Victoria, 1300 55 81 81, general complaint form.
• QLD: Office of Fair Trading, 13 QGOV (13 74 68), consumer complaint.
• ACT: Access Canberra, 13 22 81, get help with a consumer issue. It needs proof that you’ve written to the business, and it also helps non-residents with an ACT repairer.
• NT: NT Consumer Affairs, 1800 019 319 or 08 8999 1999, conciliation request.
• WA: Consumer Protection, 1300 30 40 54, complaints. Its motor vehicle branch offers conciliation between repairers and customers.
• SA: Consumer and Business Services, 131 882, contact CBS.
• TAS: Consumer Affairs Tasmania, 1300 654 499, enquiry and complaint form.

Step 4: Still unpaid? Send the final demand

The final demand quotes your first letter, the workshop’s response (or silence) and any Fair Trading reference number, and states that you’ll file a claim if it isn’t paid. In South Australia the courts say a final notice should be given and you should wait 21 days before filing, or you may not recover your filing costs.

Send the final demand – $49

Step 5: File at the tribunal or court in the workshop’s state

Your claim goes to the consumer tribunal or court in the state where the workshop is (see the table below). In NSW, a repair claim is an NCAT motor vehicle claim. In Queensland, a consumer-law claim relating to a motor vehicle, including a repair claim, is a QCAT motor vehicle dispute with a $100,000 limit (Form 59), not a minor civil dispute. In WA, SA and Tasmania you file a court claim at the Magistrates Court. Bring the second repairer’s report: for a disputed repair it is often the most persuasive evidence you have. Our Hearing Bundle ($97) puts your evidence in the order a member or magistrate expects.

Prepare your tribunal application – $97

In WA, SA and Tasmania the same product prepares your Magistrates Court claim.

Where your claim goes in each state

The claim goes to the forum in the state where the workshop is, not where you live.

If the workshop is run by an individual who lives in another state. NCAT can’t decide a dispute between a permanent resident of NSW and a resident of a different state, because of the High Court’s decision in Burns v Corbett [2018] HCA 15. The claim then goes to the Local or District Court, which can make the same orders. This doesn’t apply if either party is a company, and many workshops trade through one. VCAT likewise says it can’t hear some cases where a party lives in another state. Check the workshop’s ABN record before you file.

Time limits: NCAT says to apply within 3 years of when the problem began. VCAT says generally within six years. Don’t wait: evidence about a repair goes stale quickly once the car is driven or fixed elsewhere.

After you win: getting paid

A tribunal or court order is not the end of the road if the workshop ignores it. If the workshop still doesn’t pay, the order can be enforced. In most states it is registered or filed with the court and enforced as a judgment. The main tools are a garnishee order on the business’s bank account or the money its customers owe it, seizure and sale of property, and an examination where the owner must answer questions about its finances under oath. In NSW and WA, an unpaid order against a licensed repairer may also support a compensation fund claim.

Tribunals do not collect the money for you. In NSW, Victoria, Queensland, the ACT and the NT, an unpaid tribunal money order is first registered, recorded or filed with a court. In WA, SA and Tasmania the Magistrates Court decides the claim, so you already have a court judgment. Then you apply for the court’s enforcement tools.

Questions people ask

Can a mechanic charge more than the quote?

Generally not without your agreement. NSW Fair Trading says a price agreed before work starts is generally binding, even if the job costs the workshop more. If extra work was needed, they should have contacted you first. You can dispute the difference in writing, and paying the bill to get your car back doesn’t stop you lodging a dispute afterwards.

Do I have to pay for repairs I didn’t authorise?

You have strong grounds to refuse. NSW Fair Trading says work must be limited to what you authorised, and WA Consumer Protection says repairs are authorised based on the original quote and any agreed extra work. Pay what you agreed to, dispute the rest in writing, and use our Overcharge and Invoice Dispute letter if the workshop insists.

Can a mechanic keep my car if I don’t pay?

Usually yes. NSW Fair Trading says a repairer can hold the car under a repairers lien until the bill is paid, and police can’t order its release, though a court can. If you need the car, pay, state in writing that you dispute the amount, and then claim the money back. Paying doesn’t remove your right to dispute the bill.

What if the mechanic damaged my car?

You can claim the cost of repairing the damage. A repairer must do the work with due care and skill (ACL s 60), and you can recover reasonably foreseeable loss caused by a failure (s 267(4)). Photograph the damage before you drive away, get a written quote from another repairer, and put the claim in writing. Our Consumer Guarantee Letter sets it out formally.

The same fault came back after the repair. What can I do?

Ask the workshop in writing to fix it free within a reasonable time. If it refuses or fails, you can have another repairer fix it and recover the reasonable cost, or cancel the contract (ACL s 267(2)). If the failed repair made the car unsafe, it is likely a major failure, so you can cancel and claim a refund instead.

Can I get a refund instead of another repair?

For a major failure, yes. You can cancel and recover money for work you didn’t get the benefit of, or keep the work and claim its loss in value (s 267(3)). For a minor failure, the workshop gets the first chance to fix it. If it doesn’t fix it within a reasonable time, you can cancel or get it fixed elsewhere at the workshop’s cost.

Does servicing my car at an independent mechanic void the new car warranty?

Not of itself. The ACCC says servicing at an independent repairer doesn’t affect your consumer guarantee rights, and statements suggesting otherwise may be misleading. WA Consumer Protection says independent licensed mechanics can service your car without voiding the manufacturer’s warranty, provided the work and parts meet the manufacturer’s standards, usually set out in the owner’s manual.

Do I have to pay a diagnostic fee if I don’t go ahead with the repair?

Usually yes. NSW Fair Trading says a repairer can charge a diagnostic fee and you must pay it even if you decline the repair. Ask what the diagnosis will cost before you leave the car. If the diagnosis itself was carelessly wrong and cost you money, that can be part of a due care and skill claim.

Is my mechanic licensed?

In NSW and WA, repair businesses must be licensed for work affecting a vehicle’s safety or performance, and both states publish a register you can search. In WA, licensed repairers display a yellow and black tick sign. Licensing matters if things go wrong, because the NSW and WA compensation funds generally cover licensed repairers.

How long does the workshop have to fix my car?

A reasonable time, if no date was agreed (ACL s 62). What’s reasonable depends on the job and on parts availability, and the workshop should keep you updated. If the car sits for weeks with no real progress, you can put a deadline in writing, then cancel, collect the car and claim back money paid for work not done.

Can I take a mechanic to NCAT or VCAT?

Yes. NCAT hears disputes about getting repairs done in NSW, up to $100,000, and VCAT hears goods and services claims, including repairs, with no money cap. Send a formal demand first. Our Consumer Guarantee Letter ($49) is the usual first step, and our tribunal application ($97) prepares the claim.
