Can you bring shells or coral into Australia?
Carry-on: Conditions Checked: Conditions Declare on arrival: Required Does not apply domestically
Shells and coral must be declared and need to be clean and free of any animal tissue or sand. Many corals and giant clam shells are also CITES-listed, which means they need a permit regardless of how clean they are.
Sand is treated as soil and is effectively prohibited. A jar of beach sand is one of the more common things people are surprised to lose at Australian arrivals.
Declaring is the whole game here. Under the Biosecurity Act you are not penalised for declaring something, even if the item turns out not to be allowed in - the officer simply takes it. The penalty exists for *not* declaring, and at an Australian airport that means an infringement notice rather than a warning.
So the calculation is lopsided. Ticking the box costs you a few minutes in the biosecurity queue. Not ticking it, and having a biosecurity officer find shells in your bag, costs money and can cost you a lot more than the shells were worth.
If you want shells to survive the border, buy or collect them finished: no sand inside, no dried animal tissue, no soil. Rinse and dry them thoroughly before you pack. Coral is the exception that catches people - much of it is CITES-listed, and a permit is not something you can arrange at the airport.
Flying within Australia? This one does not apply.
This is decided at the Australian border, so it does not apply to a domestic flight.
This one is decided at the Australian border rather than at screening. Declaring a thing costs nothing and a biosecurity or Border Force officer decides - it is failing to declare that carries the fine. If you are not sure whether something counts, declare it.
Shells, coral and sand: common questions
Do you have to declare shells when entering Australia?
Yes. Every shell, piece of coral and marine souvenir has to be declared on your Incoming Passenger Card, whatever condition it is in and whether it is in your carry-on or your checked bag. Declaring it costs nothing even if the item is then refused entry.
What happens if you do not declare shells at Australian customs?
A biosecurity officer who finds undeclared goods in your baggage can issue an on-the-spot infringement notice. You are not penalised for anything you declare, even goods that are not allowed in, so declaring is always the cheaper choice.
Can you bring sand back to Australia?
Effectively no. Sand is treated as soil, which is one of the highest-risk biosecurity categories, so a jar of beach sand is very likely to be taken. It still has to be declared - the penalty attaches to not declaring, not to carrying it.
Can you bring coral into Australia?
Only with the right paperwork. Many corals and giant clam shells are CITES-listed, so they need a permit regardless of how clean they are. A permit has to be arranged before you travel; it is not something that can be sorted out at the airport.
How clean do shells need to be to bring into Australia?
Free of sand, soil and any animal tissue. Rinse them thoroughly and dry them completely before packing. Anything still carrying organic material is the most likely to be treated, exported or destroyed at your cost.
Can shells go in carry-on or checked baggage?
Either. This is a border question rather than a screening one, so shells are not a security issue at the departure gate at all - what matters is the declaration you make on arrival in Australia.
