The open road offers an incredible sense of freedom, and driving holidays continue to be a top choice for making memories.

According to a 2024 survey, nearly 92 percent of Australians report taking domestic road trips. With these adventures steadily increasing in popularity, families are spending more hours than ever confined to their vehicles.

Interestingly, the data reveals that Queenslanders are the demographic most likely to embark on long-haul family drives, with almost a quarter reporting their last trip exceeded 15 hours behind the wheel. While over half of drivers proactively prepare by checking tyre pressure, oil levels, and mapping out exact routes prior to departure, true passenger comfort requires a bit more thought.

Upgrading your vehicle for long journeys can transform a stressful drive into a smooth, enjoyable experience.

Prioritise Cabin Sun Protection

A common misconception is that being inside a vehicle fully protects you from the sun. Cancer Council Australia advises that standard, untinted side car windows do not fully block UV radiation, leaving passengers vulnerable to cumulative skin damage.

This is particularly concerning for children seated in the back during long stretches of daytime driving. Recent medical data from 2025 reveals that while front windscreens provide an average of 99.25 percent UV-A attenuation, passenger side windows offer significantly less protection.

Because back-seat occupants are exposed to highly variable UV levels, adding a reliable physical barrier is essential. To combat this exposure, installing the best car side window sun shade provides a vital layer of defence that supplements standard auto glass.

Closely woven fabric window covers are heavily encouraged by skin cancer prevention organisations to substantially reduce the solar radiation transmitted into the cabin, keeping young travellers safe and comfortable.

Implement Smart Temperature Control

Australian summers are notoriously harsh, and the heat trapped inside a car can become dangerous very quickly. Regional automotive testing has demonstrated that a vehicle interior can easily exceed 40 degrees Celsius in just 30 minutes, even when parked in the shade with the windows slightly open. Health authorities warn that a child’s core body temperature can rise three to five times faster than an adult’s, making infants and toddlers highly susceptible to heat exhaustion in warm vehicles.

Parents must also be mindful of how child seats contribute to this trapped heat. Updated 2026 guidance from the sudden infant death syndrome charity Red Nose warns that heavy padding in child car restraints can significantly increase a baby’s body heat, even when the air-conditioning is running at full capacity.

Ensure your car’s cooling system is fully serviced before setting off, and always adhere to strict routines promoted by campaigns like Look Before You Lock.

During 2024 and 2025, roadside patrols responded to more than 1,700 vehicle lock-in emergencies annually, highlighting how easily a busy parent might accidentally leave a child in a rapidly heating car cabin.

Upgrade Rest and Safety Accessories

Driver fatigue is a serious risk on long-haul drives. A nationwide study found that 30.1 percent of Australian respondents have experienced a microsleep, which is a brief, unremembered lapse in consciousness, while driving on long journeys.

Taking frequent breaks is non-negotiable for road safety. The community-led Driver Reviver program operates more than 220 volunteer-run rest sites across the country, where motorists are encouraged to take a 15-minute rest break every two hours.

When outfitting your car interior for these long trips, it is crucial to avoid uncertified aftermarket child restraint accessories. Kidsafe Australia strictly advises against using products that interfere with the safe operation of a car seat. Instead, look for practical upgrades that keep the cabin safe and calm.

Organise Your Cargo for Easy Access

A cluttered car leads to a stressful environment, especially when you need to find an essential item quickly. Upgrading your storage solutions can make a world of difference for everyone on board. Consider implementing these simple cargo upgrades:

• Seat-back organisers: Hang these over the front seats to hold toys, tablets, and water bottles, keeping the back seat tidy and giving kids easy access to their entertainment.
• Boot dividers: Use collapsible crates or boot organisers to separate emergency equipment, such as a first aid kit and spare tyre tools, from your daily luggage.
• Accessible snack stations: Pack a small cooler bag that sits securely between the back seats. This prevents the need to pull over every time someone needs a drink or a piece of fruit.
• Dedicated rubbish bins: A small, leak-proof car bin keeps food wrappers and tissues off the floor, reducing mess and lingering odours.
• Readily available comfort items: Keep travel pillows and lightweight blankets in an easily reachable soft bag, so passengers can comfortably rest during the drive.

Taking the time to prepare your vehicle goes beyond the standard mechanical checks. By prioritising sun protection, managing cabin temperatures, enhancing safety accessories, and organising your cargo space, you can completely change the dynamic of your road trip. A comfortable family is a happy family, and a happy family makes for a much smoother drive.
