Can you take dry ice on a plane?
Carry-on: Conditions Checked: Conditions Same on domestic flights
Allowed with airline approval, usually up to 2.5kg per person, and only in packaging that lets the gas vent. The package has to be marked with the weight and the words "dry ice" or "carbon dioxide, solid".
Approval is per airline and not automatic. Ordinary frozen gel packs need no approval and solve most of the same problems.
Flying within Australia? This rule does not change.
The same rule applies on a domestic flight.
Two rules explain most of this page. Lithium batteries fly in the cabin so the crew can reach them, and the 100ml liquid limit is an international rule. Your flight home is screened under the departure country's rules, which are sometimes stricter than Australia's.
Flying soon? Screening is the easy part
What stops Australians at the airport is more often the passport, the visa or the phone than the bag. Say where you are going and we will show you the entry rules for an Australian passport, what an eSIM actually costs there, and what the insurance covers.
