Vape devices and spare lithium batteries must travel in carry-on baggage on every Australian flight and are prohibited in checked luggage. E-liquid may go in either, subject to liquid limits. Vaping on board is banned outright, including in lavatories. Lock your device and empty the tank before flying to prevent pressure leaks.
Flying with Vapes in Australia: What Adult Travellers Need to Know in 2026
Travelling interstate across Australia for business, holidays, or weekend getaways is routine, but flying with electronic cigarettes, pod systems, and lithium-ion batteries requires strict adherence to aviation safety regulations.
Under the Civil Aviation Safety Authority (CASA) regulations and the dangerous goods guidelines enforced by Australian airlines including Qantas, Virgin Australia, and Jetstar, vaping devices are permitted on domestic flights — provided you follow essential packing and battery rules.
The Golden Rule: Carry-On Baggage ONLY
By Australian aviation law, all electronic cigarettes, personal vaporizers, and spare lithium-ion batteries must be transported in your carry-on cabin baggage. They are strictly prohibited from checked luggage in the aircraft hold.
- Why? In the rare event of a lithium battery thermal runaway, the cabin crew is trained and equipped with specialized fire-containment equipment to immediately extinguish any battery fire in the cabin. Inside the unpressurized or cargo baggage compartment, a fire could spread unnoticed.
- Checked Bag Warning: If baggage screeners detect a vape device or loose battery in your checked suitcase during X-ray screening, airport security will physically open your bag, confiscate the device, and leave an inspection notice.
How to Prevent Vape Pod Leaks Caused by Cabin Pressure
One of the most frustrating experiences for travellers is landing at Sydney, Brisbane, or Melbourne Airport only to find their vape pod has flooded the battery chamber.
Aircraft cabins are pressurized to roughly 6,000 to 8,000 feet above sea level. As the plane climbs, the ambient air pressure drops, causing the air bubble trapped inside your vape cartridge to expand and force e-liquid outward through the coil and airflow chimney.
4 Pro Steps to Stop Leaking at 35,000 Feet:
- Detach the Pod from the Battery: Always separate your Relx Pro Pod or cartridge from your Relx Infinity 2 device before boarding. Store them separately in your carry-on.
- Keep Pods Upright or in a Sealed Bag: Place your detached pods in an upright position inside a clear zip-lock sandwich bag or protective silicone pod sleeve.
- Travel with Full or Brand-New Sealed Pods: Unopened, factory foil-sealed pods withstand pressure changes significantly better than partially used cartridges because there is virtually no trapped air bubble to expand.
- Wipe Contacts Upon Arrival: After landing, inspect the magnetic brass connection pins inside the battery slot with a tissue or cotton swab before snapping your pod back in.
Liquids & Security Screening at Australian Airports
For domestic flights within Australia, the 100ml liquid restrictions that apply to international terminals do not apply at domestic security checkpoints. You can carry your bottled e-liquids and prefilled pods through security scanners without having to separate them into clear plastic 100ml bags.
However, you must still comply with general carry-on weight limits and ensure bottles are tightly sealed to prevent accidental leaks.
Airline-Specific Policies: Qantas, Virgin Australia & Jetstar
While all Australian carriers follow standard CASA dangerous goods regulations, here are the airline-specific confirmations:
| Airline | Permitted in Cabin? | Permitted in Checked Baggage? | Charging Permitted Onboard? |
|---|---|---|---|
| Qantas | Yes (Carry-on only) | Strictly Prohibited | Strictly Prohibited (USB / Powerbank) |
| Virgin Australia | Yes (Carry-on only) | Strictly Prohibited | Strictly Prohibited |
| Jetstar | Yes (Carry-on only) | Strictly Prohibited | Strictly Prohibited |
Crucial Warning: You must never charge your vape battery using the aircraft's in-seat USB ports or portable power banks during the flight. Recharging in-flight is strictly forbidden by all Australian aviation operators.
Strict Ban on In-Flight Vaping
It goes without saying: vaping is strictly banned on all flights, inside aircraft lavatories, and within airport terminal buildings.
Aircraft smoke detectors are sensitive optical and ionization sensors capable of detecting both tobacco smoke and dense condensed glycerin vapor. Triggering a lavatory smoke alarm will divert the flight crew, result in law enforcement meeting you at the arrival gate, and trigger hefty civil aviation penalties or permanent airline bans.
Use designated outdoor smoking and vaping zones located outside the airport terminals before passing through security.
Can you take a vape on a plane in Australia?
These come from aviation safety regulation rather than individual airline preference, so they are consistent across Qantas, Virgin Australia, Jetstar and Rex, and they align with international practice.
| Item | Carry-on | Checked baggage | Use in flight |
|---|---|---|---|
| Vape device | Yes | No | No |
| Spare lithium cells | Yes, individually protected | No | - |
| E-liquid | Yes, within liquid limits | Yes | - |
| Power bank | Yes | No | - |
| Charging a device onboard | - | - | No |
The reason devices and cells cannot go in the hold is straightforward: a lithium fire in an inaccessible cargo compartment cannot be dealt with, whereas one in the cabin can. This is why the rule is absolute rather than advisory.
Packing properly
- Lock the device. Five rapid clicks on most regulated devices. A device that fires in a bag generates heat with nowhere to go.
- Protect spare cells individually. Plastic battery cases, or tape over the terminals. Loose cells in a bag with keys or coins are exactly the scenario the rule exists to prevent.
- Empty or part-empty the tank. Cabin pressure changes push liquid through the airflow. A full tank in a bag will usually leak.
- Bag your liquids. Even on domestic flights where the 100 ml rule may not apply, a sealed bag saves your belongings if a bottle weeps.
- Carry the device where you can reach it, not buried in an overhead bag, so you can respond if it becomes warm.
Liquid limits
On domestic Australian flights there is generally no 100 ml restriction on liquids in carry-on, so a full-size bottle is usually fine. On international departures the 100 ml container limit inside a one-litre transparent bag applies, and bottles larger than that must go in checked baggage — which is permitted for liquid, unlike devices and cells.
Screening rules change, and individual airports apply them with some variation. Checking your airline's dangerous goods page before travelling costs a minute and avoids losing something at the checkpoint.
Using a vape at the airport and in flight
Vaping is prohibited on board every Australian flight, including in lavatories, where smoke detectors will pick it up. The consequences are serious and routinely include removal from the aircraft and referral to police. There is no ambiguity here and no carrier treats it leniently.
Airport terminals are smoke-free environments under state law. Some airports provide designated outdoor smoking areas, generally landside, and these usually permit vaping — but once you are through security you are typically committed until you land.
Interstate and international considerations
Rules on possession and use vary by state within Australia, and vary dramatically overseas. Several countries in the region — Thailand, Singapore and India among them — prohibit vaping products outright, with penalties that can include confiscation, substantial fines or detention. Carrying a device into one of those jurisdictions, even in transit, is a genuine risk rather than a technicality.
Check the destination's rules before you fly, not after you land. A country's tourism guidance is rarely the right source; the relevant customs or health authority is.
A short pre-flight checklist
- Device locked and in carry-on.
- Spare cells in cases, in carry-on.
- Tank emptied or nearly so.
- Liquids bagged, and within limits if flying internationally.
- Nothing vape-related in checked baggage except sealed liquid.
- Destination rules checked.
