Liquids, aerosols & gels

To protect you from the threat of liquid explosives, the Australian Government has a few rules for taking liquids, aerosols and gels within your carry-on baggage on flights in and out of Australia.

Domestic flights

Flights within Australia are not subject to restrictions on how much liquid, aerosols and gels you can carry onboard.

International flights

Quantity restrictions

There are restrictions on the quantity of liquids, aerosols and gels you may carry, including duty free liquids, aerosols and gels. These restrictions do not apply to your checked baggage carried in the hold of the aircraft. 

When you pack for international travel, pick your liquids, aerosols and gels – such as creams, perfumes, sprays, gels, toothpaste, lip balms and similar substances – carefully, making sure no container exceeds 100ml.

You’ll need to present these items in a clear, resealable plastic bag to show to security screening officers. We provide plastic bags at international security screening points to help make the screening process as easy as possible, however we recommend you prepare these items before arriving at the airport.

For further details about liquid, aerosol and gel restrictions and how they need to be presented at the screening point, visit the Australian Government’s Travel Secure website.

Items purchased from an off-airport duty free shop

It is recommended that duty free liquid, aerosol or gel items purchased from a duty free shop that is not at Perth Airport be placed in your checked baggage. Goods must be in a sealed bag and have the accompanying receipt provided at time of purchase alongside them. 

Alternatively you can present the items at the screening point to undergo security screening. In both cases, you must have the receipt ready for inspection as you proceed through passport control and the security screening point. If the screening process clears the items, you will be able to take them on board your flight. If the screening process does not clear the items, you will be asked to surrender them.


Necessary prescription and non-prescription medicines (including special dietary products), medical items and baby products are exempt from the 100ml limit.

Exempt items do not have to be carried in the clear, resealable plastic bag, however, you’ll need to present them separately at the security screening point.
