Frequently Asked Questions

What are the restrictions for powders, liquids, aerosols and gels (PLAGs) in carry on baggage?

If you're travelling overseas, there are restrictions on the quantity of liquids, aerosols and gels and some powders (PLAGs) you may carry onboard, including those purchased from duty free. These restrictions apply to all passengers leaving on international flights, as well as those transiting and/or travelling on the domestic leg of an international flight within Australia. Exemptions apply for medicines, medical products, medical devices and baby products that you may need during your journey.

Flights within Australia are not subject to PLAGs restrictions for onboard baggage. However, if you are travelling domestically, but departing from T1 International, you are subject to powder, liquid, aerosol and gel restrictions. Visit the Home Affairs website for more information.

What items are prohibited items that cannot be carried onboard an aircraft?

Items classified as prohibited items, including weapons and dangerous goods, cannot be carried onboard an aircraft. If you have any of these items in your carry on baggage, you will need to surrender these at the screening point.

If in doubt about whether an item can be carried onboard, check with your airline prior to arriving at the airport. In some cases, you may be able to pack the item in your checked baggage. Please refer to the Home Affairs website for further information.

I am travelling internationally, can I bring baby products onboard with me?

You are allowed to carry onboard a reasonable quantity of powder, liquid, aerosol or gel items for a baby or infant for international flights. Pack only what you need for the duration of a flight and any delays that may occur. There are no quantity restrictions for organic powders such as powdered baby formula.

Baby products may include milk, including expressed breast milk and powdered formula, sterilised water, juice, and baby food in liquid, gel, powder or paste form.

For more information and to view the full list of baby and infants products, please visit the Home Affairs website.

What can I bring when arriving into Australia?

The Australian Government has strict security measures and procedures restricting or prohibiting certain items you can bring into Australia. For more information on what you must declare and what you cannot bring into Australia, please visit the Australian Border Force website.

How do the body scanners at the airport work?

All body scanners in Australia use non-ionising millimetre-wave technology. This means they do not emit ionising radiation like that of x-rays.

The low intensity waves and short duration of the scan means you are exposed to less energy than other common everyday devices such as mobile phones. The millimetre-waves are reflected off the surface of the skin and do not penetrate the body.

There are no known health risks from undergoing a scan so travellers who have a medical condition or are pregnant should not be concerned.
