Carrying cash from Australia to Singapore
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 Australia, AUSTRAC requires a declaration above AUD 10,000. Entering Singapore, Immigration & Checkpoints Authority requires a declaration above SGD 20,000. The two rules are independent: satisfying one does not satisfy the other.
The two legs
| Leg | Limit | Form | Authority |
|---|---|---|---|
| Leaving Australia | AUD 10,000 | Cross-Border Movement: Physical Currency Form | AUSTRAC |
| Entering Singapore | SGD 20,000 | CBNI declaration (via the Singapore Arrival Card or the official app) | Immigration & Checkpoints Authority |
The same duty applies moving money out. Bearer negotiable instruments payable to any person must also be reported.
Required when the total value EXCEEDS S$20,000, exactly S$20,000 does not trigger it. The duty applies whether the cash is yours or carried for someone else.
If you do not declare
Australia: Significant fines; undeclared cash may be seized.
Singapore: An offence under the Corruption, Drug Trafficking and Other Serious Crimes (Confiscation of Benefits) Act 1992.
Neither threshold on this route is a cap: you may carry more, but above it the duty is to report the cash, not to keep under the figure. Failing to report is the offence.
Currencies
Australia uses AUD; Singapore uses SGD.
