Why this matters

Australia runs one of the strictest biosecurity borders in the world, and tea sits right in its sights because it is dried plant material. Plain tea leaves are low risk, but the moment a blend includes seeds, dried fruit, or flowers, it can carry exactly the pests and plant diseases Australia works hardest to keep out.

The practical risk for travellers is not the tea itself — it is the declaration. Every food and plant product must be ticked on the Incoming Passenger Card. An undeclared box of tea found in your bag can mean an on-the-spot fine, and Australia has cancelled visas over deliberately undeclared biosecurity goods.

Restrictions

What usually clears without trouble:

  • Commercially packaged black, green, white, or oolong tea — leaves or bags — in sealed, labelled retail packaging, declared on arrival.

What attracts scrutiny or seizure:

  • Herbal and fruit blends containing seeds, dried berries, citrus peel, whole flowers, or roots.
  • Blends with ingredients an officer cannot identify from the label.
  • Loose tea in unlabelled bags, homemade mixes, or tea bought at markets without ingredient lists.

The decision is always made at the border. Declaring tea costs you a few minutes at the biosecurity channel; not declaring it can cost you a fine several hundred dollars larger than the tea is worth.

What the official guidance says

The Department of Agriculture, Fisheries and Forestry treats tea as a plant product that must be declared. Commercially prepared and packaged tea is generally permitted into Australia for personal use, while blends containing seeds or other viable plant material may be directed for inspection, treatment, or destruction. The Australian Border Force's "Can you bring it in?" guidance repeats the core rule: when in doubt, declare it, and let the biosecurity officer make the call. A declared item that turns out to be prohibited is simply taken — there is no penalty for declaring honestly.
