Carrying cash from United States to Australia
Two separate rules apply to any cash journey: one where you leave, one where you arrive.
Do you need to declare?
Yes: and on both legs of the journey. Leaving United States, U.S. Customs and Border Protection requires a declaration above USD 10,000. Entering Australia, AUSTRAC requires a declaration above AUD 10,000. The two rules are independent: satisfying one does not satisfy the other.
Travelling as a family or group?
The threshold applies to your combined total, not per person. A family of four each carrying a little under the limit is still over it, and splitting cash between travellers to stay under does not make it legal.
The two legs
| Leg | Limit | Form | Authority |
|---|---|---|---|
| Leaving United States | USD 10,000 | FinCEN Form 105 (CMIR) | U.S. Customs and Border Protection |
| Entering Australia | AUD 10,000 | Cross-Border Movement: Physical Currency Form | AUSTRAC |
The same reporting duty applies when leaving the United States.
Declare A$10,000 or more moving into Australia, counting Australian and foreign currency together.
If you do not declare
United States: Seizure of the currency and possible civil and criminal penalties.
Australia: Significant fines; undeclared cash may be seized.
There is no limit on how much you may legally carry in either direction, the duty is to report it, not to keep under it. Failing to report is the offence.
Currencies
United States uses USD; Australia uses AUD.
