Australia has the world's most aggressive biosecurity enforcement. Here's the current penalty structure, what to declare, and how to land without a fine.
🚨 The Most Common Mistake: "It's Just One Piece of Fruit"
That apple from your in-flight meal, a forgotten muesli bar, or untreated wooden souvenirs are the top reasons travellers get fined at Australian airports. Detector dogs have an 11% hit rate on secondary screening. The fix: eat it, bin it in an amnesty bin, or declare it — never carry it through the green lane.
| Violation | Penalty |
|---|---|
| Undeclared low-risk item (standard) | 2 penalty units — AUD $660 |
| Undeclared high-risk goods (meat, seeds, plant material) | 6–12 penalty units — AUD $1,980–$3,960 |
| Concealed items (hidden or deliberately obscured) | 20 penalty units — AUD $6,600 |
| Serious/repeat breach | Court prosecution up to AUD $396,000 + possible imprisonment |
Penalty units are valued at $330 each as of 2026 under the Biosecurity Act 2015. Officers have no discretion to waive these once an undeclared item is found — the amount is not negotiable.
| Item | Allowance |
|---|---|
| General goods | AUD $900 per adult (AUD $450 for under-18s) |
| Alcohol | 2.25 litres duty-free (18+ only) |
| Tobacco | 25 cigarettes or 25g of tobacco products (18+ only) |
Currency over AUD $10,000 (or equivalent) must be declared. There is no limit on how much you can carry — only a declaration requirement.
❓ Frequently Asked Questions — Australia Customs
What happens if I forget to declare a piece of fruit from my flight?
If found, it results in an on-the-spot infringement notice starting at AUD $660 for a standard undeclared item, rising to $1,980+ for higher-risk items like meat or seeds. Declaring costs nothing — undeclared and found costs hundreds of dollars.
Can my visa be cancelled over a biosecurity fine?
Yes. For non-citizens, serious or deliberate biosecurity breaches can lead to visa cancellation and a re-entry ban, in addition to the financial penalty.
Are commercially packaged snacks from duty-free shops safe to bring?
They generally clear biosecurity more easily than fresh items, but they still must be declared on your Incoming Passenger Card. Undeclared is undeclared, regardless of packaging.
Do officers have discretion to waive a biosecurity fine?
No. Under the Biosecurity Act 2015, the penalty unit amount is fixed by legislation — officers cannot reduce or waive it once an undeclared item is confirmed.
What counts as a 'concealed' item that triggers the maximum fine?
Anything hidden in false compartments, buried in luggage lining, or deliberately obscured from a routine inspection. This tier carries the harshest on-the-spot fine — AUD $6,600.
