The person who books the car is not always the only person who will drive it. On a family holiday, a long run between Melbourne and regional Victoria, or a busy work trip, sharing the driving can make the journey easier. But additional driver rules matter because anyone who gets behind the wheel needs to be properly covered under the rental agreement.

The simple rule is this: if a person may drive the rental car, tell the rental company before they do. Do not assume a partner, colleague or family member is automatically included because they are travelling with you. Adding a driver at collection usually takes only a few minutes. Sorting it out after an incident can be far more difficult.

What is an additional driver?

An additional driver is anyone approved to drive the rental vehicle besides the primary renter. The primary renter is the person whose name is on the rental agreement and who takes responsibility for the booking, payment and vehicle return.

An approved additional driver is listed on that agreement. They are generally subject to the same key conditions as the main renter, including licence requirements, age rules and the obligation to use the vehicle lawfully and with reasonable care.

This is not just paperwork. Rental insurance and damage liability are tied to the agreement. If an unlisted person drives the car, cover may be reduced or excluded, and the primary renter may still be responsible for costs. That is a risk not worth taking to save a few minutes at the counter.

Additional driver rules: what to check before you book

Rental conditions differ between companies and vehicle types, so always read the terms for your booking. The following points are the ones worth checking early, especially if you are arriving on a flight and want a quick pickup.

Each driver needs an acceptable licence

Every driver should bring their current physical driver licence to collection. A photo of a licence on a mobile is not always accepted, and an expired licence will not do. The name on the licence should match the name being added to the agreement.

For overseas visitors, a valid licence from home may be accepted where it is in English. If it is not in English, you may need an international driving permit or an accredited translation as well. Requirements can depend on the issuing country and the rental company, so check before travelling rather than finding out at the airport.

Probationary, provisional and learner licences can also have different conditions. If one of your drivers is on P-plates, contact the rental provider before booking. The answer may depend on their age, how long they have held a licence and the vehicle category.

Age requirements apply to every driver

It is common for car hire companies to set a minimum driver age, and some apply an age surcharge or different excess conditions for younger drivers. These rules apply to additional drivers too, not only the person making the booking.

There may also be age limits for certain vehicles. A larger people mover or SUV can have different eligibility requirements from a small economy car. If your group plans to share driving duties in an 8-seater, make sure every intended driver qualifies before you arrive.

The additional driver usually needs to be present

In most cases, the rental team needs to see each additional driver and check their licence before adding them. That means the person should come to the collection desk or meeting point with the primary renter.

This can catch travellers out when one person collects the car while everyone else waits for bags. If another adult will drive later in the trip, have them complete the paperwork at pickup. It is usually much easier than trying to add them once you are already on the road.

Fees and inclusions vary

Some rental rates include an additional driver, while others charge a daily fee or set a limit on the number of drivers. There is no one rule across Australian car hire, so check the quote and rental terms rather than relying on what happened with a previous booking.

The cheapest-looking rate is not always the best value if it leaves out something your trip genuinely needs. Compare the total cost, including any driver fee, with the convenience of sharing a long drive. Straightforward pricing makes that decision easier.

Why being listed on the agreement matters

The practical benefit is simple: a listed driver can take over legally under the rental terms. The more serious reason is what happens if something goes wrong.

A minor scrape in a car park, a broken windscreen on a country road or a collision can become much more complicated when the person driving was not authorised. The renter may lose the benefit of optional cover, face a higher financial responsibility or breach the rental agreement altogether. Even where no damage occurs, unauthorised driving can create a problem if the vehicle is stopped or needs roadside assistance.

There is another consideration: fatigue. Australia’s distances can be deceptive. A route that looks manageable on a map may feel very different after a flight, a delayed pickup and several hours on unfamiliar roads. Adding a qualified second driver can be a sensible choice when it means both people can stay rested and focused.

Choosing the right car when drivers are sharing

The vehicle should suit all approved drivers, not just the person who booked it. Someone comfortable in a compact Toyota Yaris may prefer it for city parking, while a family with luggage and several drivers might find a Toyota RAV4 more practical. For a larger group, an 8-seater Kia Grand Carnival gives everyone space, but every driver should feel comfortable handling a bigger vehicle.

Think about where you will drive, how much luggage is coming along and whether drivers are used to Australian road conditions. Visitors from countries that drive on the right may need time to adjust to driving on the left, roundabouts and local speed limits. The best handover is not on a busy freeway. Let a less familiar driver start somewhere quiet, adjust mirrors and controls, and get comfortable before a longer leg.

A quick check before collection

Before heading to the rental location, make sure you have four things sorted:

• The names of every person who may drive during the hire.
• A current physical licence for each driver, plus supporting documents for non-English licences if required.
• Confirmation that each driver meets the applicable age and licence conditions.
• Enough time at collection for each driver to be added to the agreement.

Also check the booking name carefully. The primary renter generally needs to be present, hold the payment method required by the rental company and sign the agreement. An additional driver cannot simply collect the car in their place unless the booking has been changed under the provider’s rules.

Can you add a driver after collecting the car?

Sometimes, but do not count on it being quick or possible at every location. The rental company will normally need to verify the new driver’s licence and update the agreement before they drive. That may mean returning to an airport branch or arranging approval another way.

If plans change, contact the rental company first and ask what is required. Do not hand over the keys and assume you can update the paperwork later. This is particularly relevant for one-way hires, where you may be a long way from the original collection point by the time another person needs to drive.

A straightforward way to avoid trouble

At Kangaroo Rentals, the aim is to keep car hire practical rather than turn it into a hard-sell exercise. The clearest approach is still the best one: tell the team who will be driving, bring the right licences and make sure everyone is added before leaving.

A few minutes spent checking the agreement at collection gives everyone more freedom to share the trip, take breaks when needed and enjoy the drive with fewer surprises.
