How Long You Can Keep a Replacement Car in NSW

You can keep a not-at-fault replacement car for as long as it reasonably takes to get you back on the road: the repair period if your car is repaired, or the period it takes to be paid and buy a replacement if it is written off. There is no fixed number of days in the legislation. What matters is that the period is reasonable, and that you can show why.
That is the short answer. The longer answer is that the clock starts when your car comes off the road, pauses for nothing, and stops at a point you can defend with dates, quotes and messages. This page sets out how the period is measured in practice in Sydney, what ends it early, and how to keep records that hold up when an insurer pushes back.

What reasonable period means in practice
NSW does not set a fixed number of days for a not-at-fault replacement car. The obligation on the at-fault driver comes from the common law, most clearly in Arsalan v Rixon, where the High Court confirmed that a not-at-fault driver can recover the reasonable cost of hiring a substitute vehicle while theirs is off the road. Reasonable is the whole test, and it is measured against your circumstances, not a call centre script.
In practice, reasonableness has three moving parts:
- Your car. A prestige or performance vehicle takes longer to source a like-for-like substitute for, and longer to repair, than a base model hatch.
- The delay. If the delay is caused by the at-fault insurer, by parts availability, or by a repairer's backlog, that time is generally recoverable.
- Your conduct. If you sit on a payout for three months without looking at a single car, the later weeks start to look unreasonable.
The period is not a reward and not a penalty. It is compensation for being deprived of your car. A BMW X5 owner in Mosman whose car is off the road for eleven weeks while a rear quarter panel and radar module are sourced from Germany is in a different position from someone whose bumper is painted in four days.
If you have been hit and you are still working out what you are entitled to, start with not at fault explained and like for like before you agree to anything on the phone.
The clock starts when your car is off the road
The hire period does not begin when you sign a hire agreement. It begins when your car becomes undriveable, or when it is unsafe or unlawful to drive it, whichever comes first. That is usually the moment of the crash, or the moment a repairer tells you not to drive it further.
In Sydney, that distinction matters more than people expect. If you are rear-ended on Military Road at Neutral Bay on a Friday afternoon and your car is drivable but the boot will not latch, the clock may not start until the assessor sees it on Monday. If the car is towed from the scene, the clock starts on the tow truck.
What to do in the first 24 hours:
- Photograph the damage, the position of both cars, and the other driver's plate and licence.
- Get the other driver's insurer and claim number if they will give it. If they will not, note that too.
- Do not admit fault, even conversationally. Insurers read statements literally.
- Call your own insurer to notify, but be clear you are claiming against the at-fault party.
- Get the car assessed quickly, so the off-road date is documented.
The off-road date is the anchor for everything that follows. If it is not documented, the at-fault insurer will try to argue the clock started later. Our first 24 hours page walks through the sequence, and evidence to collect at the scene covers what to photograph before the cars are moved.

Age limits are set per car. Drivers under 25 can hire most cars with Young Driver Cover; the exact terms are shown before you pay.
Repair path: the period ends when the keys come back
If your car is repaired, the reasonable period generally runs from the off-road date to the date the repair is complete and the car is returned to you in a roadworthy condition. Not the date the repairer says it is finished. Not the date the invoice is issued. The date you can actually drive it.
That sounds obvious until you have lived through a prestige repair in Sydney. A Porsche Macan waiting on a front bumper and parking sensors can sit at a Silverwater or Alexandria repairer for two weeks after the panel work is done, because the calibration needs a specific scan tool and the technician is booked out. Those two weeks are part of the period, not a gap in it.
What typically extends the repair period:
- Parts on backorder from Germany, the UK or Japan.
- Repairer backlog after a hailstorm or a run of wet-weather crashes on the M2 or the M5.
- Supplementary assessments when hidden damage is found after the panels come off.
- Insurer assessment delays, especially where the at-fault insurer is slow to authorise.
- Calibration and ADAS work on newer cars, which needs a specialist and a clear bay.
If your repair is dragging, read how long prestige car repairs take in Sydney and parts delays. The hire period usually tracks the repair period, so a repair delay is a hire period question too.
When your car is in the shop and you need something equivalent to drive, this is the point to look at what is available: your car is being repaired.

Start my claimWrite-off path: the period runs while you replace the car
If your car is a write-off, the period is different. It runs from the off-road date until you have had a reasonable opportunity to receive the payout and buy a replacement. The insurer does not get to end the hire on the day it decides to write the car off, because you still do not have a car.
In NSW, a statutory write-off cannot be re-registered, and a repairable write-off has its own process. Either way, the practical sequence is:
- The assessor declares the car a write-off.
- The insurer makes an offer, which you can accept, negotiate, or in some cases take as a cash settlement instead of a repair.
- You receive the funds.
- You find and buy a replacement.
The hire period generally covers steps two to four, provided you are moving. A week to review the offer is reasonable. A month of silence is not. If you are negotiating the payout, keep the emails and note the dates. If you are shopping, keep the listings you enquired about and the dates you inspected.
Two things trip people up. First, the payout landing in your account does not automatically end the hire; you still need time to buy. Second, waiting for a factory order on a new build is usually too long, because the at-fault driver is not obliged to fund a six-month wait for a bespoke specification.
For the mechanics of the payout, see statutory write-off NSW and cash settlement vs repair. If you are already shopping, buying a new car after a write-off covers the practical steps.
What counts as reasonable when you are shopping
Once you are in the market, reasonableness is judged by your effort, not by the result. You do not have to buy the first car you see, but you do have to be looking. Insurers and their lawyers look for evidence of a genuine search: enquiries, inspections, test drives, finance applications, and a decision.
What a reasonable shopping period looks like in Sydney:
- Enquiring on multiple listings within the first week of having funds.
- Inspecting two or three cars in person, not just scrolling.
- Getting a pre-purchase inspection on anything used.
- Making an offer or applying for finance within a fortnight.
- Settling within a few days of agreeing a price.
What does not look reasonable:
- Waiting for a specific colour or option combination that may never appear.
- Holding out for a price below market for weeks.
- Not replying to dealers or sellers.
- Leaving the payout in a savings account while you decide.
If your car was a seven-seat prestige SUV, the like-for-like replacement is a seven-seat prestige SUV, not a compact hatch. That is the standard the hire should be measured against, and it is also the standard your replacement purchase should be measured against. Our replacement by car type page sets out how the tiers work.
If you need a like-for-like vehicle while you shop, these are the kinds of cars that match a large prestige SUV:

What ends the period early
Several things can bring the hire period to a close before you feel ready. Knowing them in advance stops the surprise.
- Your car is returned to you. Once the keys are back and the car is roadworthy, the need for a substitute ends.
- You accept a payout and stop looking. If you have funds and you are not shopping, the clock is against you.
- You buy a car. The day you take delivery of a replacement is generally the end of the reasonable period, even if you have not sold the old one.
- You unreasonably refuse a fair offer. Holding out for an unrealistic figure can cut the period short.
- You stop responding. Ignoring the insurer's requests for updates is the fastest way to have the hire questioned.
- You leave the country or the car sits unused for weeks. If you are not using the replacement, the need is harder to justify.
There is also the question of who is paying. If you are on a credit hire arrangement, the hire company is carrying the cost and recovering it from the at-fault insurer. That does not change the reasonable period, but it does mean the file needs to be clean. Our how credit hire works page explains the arrangement, and repair delays and who pays for the hire car covers the common dispute.
Keeping records that protect the claim
The single best thing you can do for the length of your hire is keep a simple, dated file. Insurers do not argue with a clean timeline; they argue with gaps.
Keep the following, ideally in one folder or email thread:
- The police event number, if you reported it.
- The other driver's name, insurer, claim number and plate.
- Photos of the damage on the day.
- The tow docket and the date the car was taken off the road.
- The repairer's assessment and every update they send you.
- Every email, text and letter from both insurers, with dates.
- Your own notes of phone calls: who, when, what was said.
- For a write-off: the offer, your counter, the settlement date, and your car search records.
A short table helps when the insurer asks why the hire ran as long as it did:
| Date | Event | Evidence |
|---|---|---|
| Day 1 | Collision, car towed | Photos, tow docket |
| Day 4 | Assessor inspects | Assessment report |
| Day 19 | Parts ordered | Repairer email |
| Day 52 | Car returned | Collection receipt |

What happens if the insurer disputes the length
Disputes about the length of a hire are common, and they usually follow the same script. The at-fault insurer argues the period should have been shorter, or that the daily rate was too high, or that you did not mitigate your loss. Your answer is the timeline and the reasonableness of each step.
How these disputes usually resolve:
- You provide the timeline. Dates, evidence, and a short explanation of any delay that was outside your control.
- The hire company responds. If you are on credit hire, the hire company handles the recovery and the correspondence.
- The insurer pays, negotiates, or refuses. Most settle. Some negotiate a reduced period. A few refuse and end up in a tribunal or court.
- If it goes further. The file goes to the hire company's lawyers or yours, depending on the arrangement.
What helps you most is not arguing about the law on the phone. It is being able to say: here is when my car came off the road, here is what the repairer said, here is when the parts arrived, here is when I got the car back, and here is what I did each week in between.

How the period plays out for a prestige car in Sydney
Prestige and performance cars sit at the harder end of the reasonable period, for two reasons: they take longer to repair, and they take longer to replace.
A BMW M3 or a Mercedes-AMG C63 hit on the Cahill Expressway or in the Rozelle interchange often needs panels, sensors and calibration that a general repairer cannot do. Parts come from overseas. The car may sit at a specialist in Artarmon or Botany for weeks. Meanwhile, the like-for-like replacement is not a Corolla; it is another performance sedan or SUV, and those are not sitting on every corner.
On the write-off side, replacing a prestige car takes longer because the market is thinner. There may be four comparable cars in NSW and none in the colour you want. The reasonable period accommodates that, but only up to a point. You are expected to buy a comparable car in comparable condition, not the exact car you had.
If your car is a performance model, BMW M and AMG replacement cars covers what like-for-like looks like. If it is a fleet vehicle, fleet vehicle repair and write-off delays and business and fleet explain how downtime is handled when a business is losing a vehicle, not just a driver.
Wherever you are in the process, the same principle holds: the period is as long as it reasonably needs to be, and no longer. Document it, keep moving, and you will not have to argue about it later.
