The reasonable hire test for replacement cars in NSW
A reasonable hire car in NSW is one a court would accept as a genuine attempt to replace what you lost, judged on what you knew when you hired it, not on what an insurer says months later. The test is not a price list. It is a set of factors insurers, assessors and judges weigh together.
If your car was hit and you were not at fault, you can recover the cost of a replacement vehicle that is reasonable in the circumstances. This guide turns that vague phrase into a working test you can apply before you sign anything, with the factors that actually decide claims in Sydney.
Key takeaways
- Reasonableness is judged on what you knew when you arranged the hire, not on how the repair turned out.
- The starting point is always your own car: body type, seats, drivetrain, tier and condition.
- Duration should match the repair timeline plus a short buffer, supported by written repairer advice.
- A cheaper alternative only defeats your claim if it was genuinely available to you at the time.
- You have a duty to mitigate, so return the car promptly and do not upgrade mid hire.
- Reasonableness is judged at the time, not in hindsight
- The starting point: what you were driving
- Availability: what you could actually get
- Duration: how long is reasonable
- Rate: how the daily cost is assessed
- Mitigation and the duty to keep costs sane
- Where prestige cars sit in the test
- Red flags in a hire agreement
- Applying the test before you book
Reasonableness is judged at the time, not in hindsight
The most common mistake insurers make is to assess your hire with the benefit of hindsight. They look back at how the repair unfolded and argue you should have known it would take three weeks, not eight. That is not the test.
The High Court in Arsalan v Rixon confirmed that reasonableness is assessed at the time the hire was arranged, on the information reasonably available to you then. If your panel beater in Alexandria told you parts for a European bumper were six weeks away, and you hired for six weeks on that advice, you were reasonable. If the repair then finished early, that does not make the hire unreasonable.
This matters because insurers routinely send letters arguing a hire was excessive after the fact. Those letters are often bluff. What counts is what you knew, what you were told, and what a sensible person in your position would have done on that day.
Keep everything that shows your state of mind at the time: the repairer's emails, the parts delay notices, the tow truck docket, the messages from the insurer. That is your evidence base.
Read the full breakdown of the decision on our Arsalan v Rixon page.
The starting point: what you were driving
The test starts with your own car. A replacement is reasonable if it puts you back in a vehicle of broadly comparable make, model, age, condition and function. Not identical, comparable.
If you were driving a 2021 Audi Q7 with seven seats and you have three kids in car seats, a Corolla is not a comparable replacement. It does not carry the same load, does not tow the same trailer, and does not serve the same purpose. The hire company's own category system is a rough guide, but the real question is what the car did for you.
Factors that push the comparison up or down:
- Body type and seating. A seven seat SUV replaced by a five seat sedan is a functional downgrade.
- Drivetrain. If you need AWD for a Blue Mountains commute in July, a front wheel drive hatch is not like for like.
- Transmission and towing. A dual cab ute with a tow bar replaced by a small SUV changes what you can do on the weekend.
- Badge and tier. Prestige and performance cars sit in their own bracket, and insurers know it.
- Age and condition. A tidy 2019 car is not fairly replaced by a 2012 with 200,000 kilometres.
Write down what your car actually did in the week before the crash. School runs, site visits, the boat ramp at Rose Bay, the drive to Bowral. That list is your argument for like for like.
More on this in our like for like guide.
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.
Availability: what you could actually get
Reasonableness is not measured against a fantasy car. It is measured against what was realistically available to you, at short notice, in your area, on the day you needed it.
This cuts both ways. If you were driving a common vehicle and there were ten equivalent cars sitting at a depot in Mascot, hiring something far above that tier is hard to defend. But if you drive a prestige car and the only comparable vehicles available were through a specialist provider, that is what availability looked like.
Practical points for Sydney drivers:
- Short notice matters. Most not at fault hires start within 24 to 48 hours of the crash, often while you are still dealing with the tow.
- Location matters. If you are in Parramatta and the closest comparable car is in Alexandria, delivery is part of the arrangement, not a luxury.
- Timing matters. December and January are brutal for availability. School holidays and long weekends empty the depots.
- Your own commitments matter. If you have a booking at the Hunter Valley on Saturday, you need a car that can do the trip, not a city runabout.
When a hire is arranged through a specialist provider, the booking is fulfilled by Drive Tribe (drivetribe.com.au), the trading name of Australian Business Holdings Pty Ltd, and this site is part of that group. Rates, bonds and fees are shown on the car's page before payment.

Start my claimDuration: how long is reasonable
Duration is where most disputes live. The rule is straightforward: you can hire for as long as the repair reasonably takes, plus a short, sensible buffer.
What is reasonable depends on the car and the damage. A prestige car with aluminium panels, radar sensors and adaptive headlights can sit in a repairer for weeks waiting on parts from Germany or Japan. A mainstream car with a damaged door might be back on the road in five days.
Things that legitimately extend the timeline:
- Parts on backorder, with written confirmation from the repairer.
- Repairer capacity. Good shops in Artarmon, Botany and Silverwater are booked out.
- Insurer assessment delays, including requests for a second quote.
- Supplementary damage found once the car is stripped.
- Paint matching and curing time on multi stage finishes.
Things that do not extend it: you going on holiday and leaving the hire car in the garage, or the repair being finished while you are overseas. The duty to mitigate applies to duration as much as to rate.
If the repair is genuinely dragging, document it. Our page on insurer delays covers how to keep the clock honest.
Rate: how the daily cost is assessed
Insurers do not get to cap your hire at a number they like. They have to show that a cheaper reasonable alternative was actually available to you at the time. That is a much harder argument than most assessors admit.
When a rate is challenged, the factors that matter are:
| Factor | What it means in practice |
|---|---|
| Comparable tier | The rate should match the class of car you lost, not the cheapest car on the lot. |
| Availability at the time | A cheaper car that was not free on the day is not an alternative. |
| What is included | Delivery, insurance, unlimited kilometres and a second driver all change the effective cost. |
| Duration of the hire | Longer hires often sit at a lower daily rate than short ones. |
| Market evidence | Rates from comparable providers in the same period carry weight. |
If an insurer says your rate was too high, ask them one question in writing: which specific vehicle, from which provider, was available to me on that date at that rate? Vague assertions about market rates are not evidence.
Our credit hire guide explains how the rate is set and who carries the risk.
Mitigation and the duty to keep costs sane
You have a duty to mitigate your loss. In plain English, you cannot run up a bill you did not need and expect the at fault driver to pay it. This duty is real, and it is the strongest weapon an insurer has.
What mitigation looks like in practice:
- Return the car promptly once yours is repaired or you are paid out.
- Do not keep a hire car while you are overseas for three weeks.
- Do not upgrade tiers mid hire because you like the bigger car.
- Accept a reasonable like for like vehicle when one is genuinely offered.
- Tell the provider if your circumstances change, such as a write off settlement.
What mitigation does not require: accepting a downgrade, taking a car that does not fit your family, or signing a hire agreement that leaves you personally exposed to a claim you did not cause.
If your car is written off, the clock behaves differently. Read repairs and write offs before you assume the hire ends on the day of the payout.

Where prestige cars sit in the test
Prestige and performance cars are not automatically unreasonable. The test is the same: what did you lose, and what was a fair replacement for it?
If you were driving a late model Range Rover Sport, the reasonable replacement is a comparable large luxury SUV, not a base model hatchback. If you were driving a seven seat luxury SUV with kids and gear, the replacement needs seven seats and the same capability.

Each of these sits in the luxury SUV bracket, with AWD, diesel economy for the daily commute, and enough space to do what the car it replaces was doing. Minimum driver age is 30 on the Range Rover Sport and the Genesis GV80, and 20 on the Audi Q7. Self drive only, with delivery available.
The point is not the badge. The point is function, tier and availability on the day. If your car was a prestige SUV and a comparable one was available, hiring it is defensible.

Red flags in a hire agreement
Before you sign anything, read the agreement like a sceptic. A well run credit hire arrangement is transparent about who carries the risk. A bad one quietly shifts it to you.
Watch for these:
- You are personally liable for the full hire if the claim fails, with no explanation of how likely that is.
- No clear end date or process for returning the car.
- Kilometre limits that do not match your normal driving.
- No written confirmation of the daily rate, bond or fees before you take the keys.
- Pressure to sign on the spot, at the scene, or in a tow truck.
- No named provider, no address, no contact details you can verify.
A legitimate provider will show you the rate, the bond and any fees on the car's page before payment. The bond equals the excess you choose. Paying by card carries a small surcharge, while bank transfer and cash on the rental do not. Cars can be booked from a single day.
If the paperwork is vague, walk away and call your own insurer or a solicitor. Our first 24 hours guide covers what to do before you sign anything.
Applying the test before you book
Here is the working test in one place. Run through it before you commit to a hire.
- What was I driving, and what did it actually do for me last week?
- What comparable vehicles were available to me, in Sydney, within 48 hours?
- How long is the repair realistically going to take, on my repairer's written advice?
- Is the rate consistent with the tier of car I lost and what was available?
- Am I returning the car as soon as the repair is done or the payout lands?
- Do I understand who carries the risk if the claim is disputed?
If you can answer those six questions with evidence, you are in a strong position. If you cannot, fix that before you sign.
