Gas Bottle Transport Regulations Australia: The 2026 Safety Guide
Quick Answer: In most Australian states and territories, two standard 9 kg LPG bottles can generally be transported when the relevant safety requirements are followed. However, the rules vary NSW limits an enclosed vehicle to 9 kg combined, while other jurisdictions apply different bottle-size, quantity, ventilation or water-capacity requirements.
If you travel with LPG gas bottles for camping, caravanning, or 4WD adventures, it’s important to understand the regulations and safety concerns before you hit the road.
While some states allow you to transport gas bottles inside your vehicle, safety experts strongly recommend against it. The risks are real and preventable.
Common Gas Transportation Questions:
How many gas bottles can i transport in a ute?
In most Australian states, you can legally transport up to two 9kg gas bottles (totalling 18kg of gas) in an enclosed vehicle. However, when using an open ute tray, safety is significantly higher as any leaking gas can dissipate into the air rather than pooling in the cabin. Always ensure bottles are secured upright in a dedicated holder to prevent rolling or valve damage.
Is it safe to travel with a gas bottle inside a car?
While transporting LPG cylinders inside a car may be legal when your state or territory’s quantity, restraint, valve and ventilation requirements are followed, it is not the safest option. LPG can accumulate inside an enclosed vehicle if a cylinder leaks and may ignite, so an open-air cargo area or properly vented external compartment is safer wherever possible.
What are the gas bottle storage requirements for camping?
When at a campsite, gas bottles must be stored in a well-ventilated area, at least 1.5 meters away from any ignition sources (like your campfire or stove). They must remain in an upright position at all times to ensure the pressure relief valve functions correctly. If you are storing them on your vehicle, ensure they are housed in a crash-resistant, secure gas bottle mount that prevents movement during off-road travel.

State & Territory Guidelines for Transporting Gas Bottles
New South Wales (NSW)
In an enclosed vehicle, you may transport up to two LPG cylinders with a combined capacity of no more than 9 kg such as one 9 kg gas bottle or two 4.5 kg gas bottles secured upright with their valves closed and POL plugs fitted.

Victoria (VIC)
When transporting LPG cylinders in Victoria, you can generally carry up to two standard 8.5 or 9kg gas bottles.
Keep each bottle upright and securely restrained, with the valve tightly closed and the protective cap or plug fitted. Protect bottles from heat, damage and ignition sources, and carry them in an open tray or externally ventilated compartment wherever possible.

South Australia (SA)
You can generally transport two standard 8.5 kg LPG bottles under the small-load exemption; three may exceed the 62.5 L combined water-capacity threshold, so check each bottle’s stamped WC, and always secure bottles upright with sealing plugs fitted and keep them out of the passenger space.

Western Australia (WA)
Do not carry an LPG cylinder larger than 9 kg in a car. Secure cylinders upright on the vehicle floor, keep the windows open for cross-flow ventilation, do not place cylinders in an enclosed boot, and remove them from the vehicle as soon as possible. An open ute tray or trailer is preferred.

The Risks of Transporting Gas Bottles Inside Your Vehicle
Even if it’s legal where you are, there are serious dangers: The main risk is that a leaking LPG bottle can fill the enclosed vehicle with highly flammable gas. LPG vapour is heavier than air, so it can collect in the footwells, boot and other low areas
• Gas leaks - LPG can pool in low areas of the car, creating an explosive environment.
• Ignition hazards - Sparks from static, electrical switches, or the engine can ignite leaked gas.
• Heat build-up - Car interiors can exceed 50 °C, raising pressure and the risk of venting.
• Crash projectiles - A loose bottle can become a dangerous missile in a collision.

A Safer Alternative - External Mounting
Safety authorities recommend mounting gas bottles outside the vehicle whenever possible. By using an external gas bottle holder:
• It will keep your gas bottles ventilated.
• Reduce the risk of gas build-up.
• Prevent bottles from becoming dangerous projectiles.
• Free up valuable interior space.
See Top End Campgear Gas Bottle Holder Range for secure external mounting sizes for 2 kg, 3 kg, 4 kg, and 9 kg gas cylinders. Secure Mount options also include Roof Rack Holders and Spare Tyre Holders
Travel safe. Follow the rules. And when in doubt, keep your gas bottles outside.
