10 Things Most People Forget Before Renting a Car in NSW
Renting a car in NSW should be simple: pick the keys up, hit the road, and enjoy the ride. But in reality, small details often get overlooked, and those slip-ups can turn a hire into a costly headache.
We’ve seen it happen: a missed scratch on the bumper or an unexpected surcharge for driving just a few extra kilometres. These things might seem minor in the moment, but they have a sneaky way of showing up on your final invoice.
In this guide, we’ll walk through the 10 things most people forget, and show how a few smart habits can help you rent confidently and drive worry-free.

Toggle1. Inspect Every Inch & Document Existing Damage
Before driving a single metre, take a slow, thorough walk around the vehicle. Look for scuffs, scratches, chipped paint, cracked lights, and windscreen chips: anything that could be pinned on you later. We’ve seen drivers handed a bill for damage they didn’t cause, simply because no one noted it before the trip began.
Use your phone to capture timestamped photos or a video walkaround, making sure to include the wheels, roof, and under the front bumper. It takes just five minutes but could save thousands in disputes.
2. Check Fuel and Fluid Levels Before You Drive Off
Never assume the car’s ready to go, even major rental companies make mistakes. Check that the fuel level matches the agreement. If your contract says it’s full, the gauge should be touching the top. If it’s not, alert staff before moving.
Pop the bonnet too. While most renters overlook this, spotting low coolant or oil before driving off can save you from being blamed for mechanical damage down the line. A quick scan of the dashboard for warning lights is also a smart final step before setting off.

3. Don’t Skip Emergency Gear & Tyres
Breakdowns happen, and when they do, being prepared makes all the difference. Every rental car should come with the basics:
- Spare tyre (inflated)
- Jack and wrench
- Hazard triangle or reflective vest
Check that all gear is present and usable. Then take a quick look at tyre pressure and tread depth. Under-inflated tyres not only wear faster but can also affect fuel economy and safety.
4. Understand Insurance & Excess
Car hire desks often push add-on insurance aggressively, but it’s worth understanding the broader picture of car insurance before you rent.
While rental agreements usually include some basic cover, it often comes with a hefty excess. You might be offered expensive excess reduction products on the spot, but these aren’t your only option.
More importantly, if you’re driving your own vehicle in Australia, not just a rental, you’re legally required to have Compulsory Third Party (CTP) insurance, also known as a Green Slip in NSW.
Providers like NRMA Insurance offer CTP cover that ensures medical costs are covered if someone is injured in an accident you cause. While it doesn’t cover vehicle damage or rental excess, it’s a critical part of staying road-legal — and responsible.
5. Scrutinise The Rental Agreement
That rental contract that comes with your Australian road trip car hire isn’t just admin, it hides some of the most important details of your hire. Look for:
- Mileage limits (some have caps)
- Fuel return rules (full-to-full is usually best)
- Extra driver fees
- Toll processing charges
- Late return penalties
Spend a few quiet minutes scanning these sections and ask questions before you sign. Many of us have learned the hard way. Surprises in the fine print rarely work in the renter’s favour.
6. Age Restrictions & Young-Driver Fees
Just because you’ve got a full license doesn’t mean you’re automatically covered. Many rental companies set a minimum age of 21 and some go higher for premium vehicles. If you’re under 25, expect:
- Daily surcharges
- Higher excess amounts
- Limited insurance options
Always check the age policy ahead of time, especially when booking through third-party platforms.

7. Book & Pay Smart
Booking last-minute often means paying top dollar, especially during peak times. But smart timing and tools help cut costs:
- Book early and track price changes
- Use comparison sites that include insurance filters
- Check cancellation policies (some let you rebook if prices drop)
We’ve shaved hundreds off week-long rentals this way. And remember, walk-up bookings at airport counters almost always cost more. Planning ahead pays off every time.
Conclusion
Renting a car in NSW should feel like freedom, not a trap. But skipping even one of these checks is how good trips turn expensive, fast.
A few minutes of prep upfront can mean the difference between a smooth ride and a stressful one. Knowing what to inspect, what to ask, and what to decline puts you back in control.
Before your next hire, run through this checklist, your wallet and your weekend will thank you.
