Trading seeds overseas.
The bottom line is don't unless you have Australian Quarantine Service (AQS) approval.
I just came back from a great trip to Canada. The Inn we stayed at before flying home had magnificent gardens and hanging baskets full of flowering plants.
When we checked out the staff hand out 2 packets of mixed seed to remember them by. I remarked they will probably be confiscated by customs on arrival back home.
The said "Oh no we have checked this out and all is OK. We have no trouble sending the seeds to Europe and the USA."
Not wanting to argue the point with their well meaning offer I took the seed packets and flew out of Vancouver for home.
We landed in Brisbane and declared the seed packets like all good OZ citizens do.
Guess what. The Customs officer seized the seeds as they were only identified by their generic name and no other information required was present. I remarked to the officer what was said in Vancouver. She just rolled her eyes and said "That figures."
I did get a nice thankyou from her for declaring them and not trying to sneak them through.
It was real nice to get a pretty smiling face and a welcome when going through customs in Australia. Not like customs in a certain country we visited. I am sure their customs officer was DRAGON LADY.
ALL incoming mail is also x-rayed, sniffed and scanned for banned imports and I am told the detection success rate is exceedingly high. Now I wouldn't like a "please explain or else" from AQS as they do have a very big stick.
