Packing for a domestic flight in Australia is significantly more relaxed than packing for an international one — but the rules are not entirely without nuance, and getting them wrong can mean confiscated items at security or a fine at a state border. Here is a complete guide to what you can and cannot take in carry-on luggage on domestic Australian flights, covering liquids, food, alcohol, vapes, power banks, and medication.

Book your flights across Australia — between Sydney, Melbourne, Brisbane, Perth, Adelaide, and regional centres:

This is the single most important difference from international travel: on domestic Australian flights, the 100ml liquid restriction does not apply. Liquids, aerosols, and gels (LAGs) can be carried in your hand luggage without any size or volume limit. You can bring full-size shampoo, perfume, sunscreen, water bottles, and similar items in your carry-on bag without needing a transparent plastic bag or worrying about volume restrictions.

The important caveat: if your domestic flight connects to an international departure, pack any liquids exceeding 100ml in your checked luggage. The international restriction applies from the moment you enter the international terminal security process, regardless of where your journey began.

You can bring food in your carry-on luggage on domestic Australian flights — sandwiches, snacks, meals, and fresh food are all permitted through security screening. However, state quarantine regulations impose significant restrictions on what food you can bring into certain states and territories:

State biosecurity fines are substantial and are enforced at arrival points. When in doubt, eat it before you land or declare it.

Alcohol in checked luggage has no specific volume restrictions on domestic Australian flights. In carry-on luggage, alcohol must remain in unopened containers — you are not permitted to consume your own alcohol during the flight. Duty-free alcohol purchased at an international airport and carried through a domestic connection must remain in sealed tamper-evident bags with the purchase receipt attached. Check individual airline policies before travelling as specifics can vary by carrier.

Vaping devices are permitted in hand luggage only — they are explicitly prohibited in checked bags due to battery fire risk. Vape liquids are allowed in carry-on without volume restrictions, provided they are securely sealed to prevent leaks. You are not permitted to charge your vaping device onboard, and vaping in airport terminals or on aircraft is prohibited under Australian law regardless of airline policy.

Power bank restrictions now apply universally across Australian domestic carriers. The rules are as follows:

Power banks are never permitted in checked luggage — they must always travel in the cabin due to fire risk management requirements.

Prescription medications should travel in their original pharmacy packaging with a copy of your prescription. There are no specific domestic restriction issues with most medications — prescription drugs are treated as permitted items. Liquid medications travel without volume restrictions domestically. If you carry temperature-sensitive medications, bring an appropriate cooler bag and confirm policies with your airline. Inhalers and insulin pumps may require medical certificates if requested at security.
