1. Just because someone says something on a radio show does not make it correct.I just heard a bloke on the radio the other day say he would be charged $10,000 to import one queen be and keep it in quarantine for 3 months. But it's not a money making exsersise.
2, Assuming this queen is a bee it may not be as simple as keeping one queen in a small cage. As a beekeeper I know that a queen bee cannot survive alone. It would have to be put into an existing hive and those bees allowed to fly, with food and water supplied daily. I don't know quarantine facilities but assume that would require a space with no other imports to prevent any possible cross contamination.
3. Maybe you have a good handle on the costs and overheads involved with keeping all these imports secure and separated and daily maintenance but I'm pretty confident the costs would not be low. Try calculating the cost of 3 months full service in a hotel room.
4. Look what the damage and costs last illegal import of queen bee has caused.
