To follow up in the last post, Australia is very active in the fight against the spread of invasive species. They have an added layer of protection in their security protocols for all incoming international flights. First, all the cabins and luggage are sprayed with a pest control substance immediately upon landing. Second, you required to declare plant and animal products. Lastly, your bags are screened by x-ray, hand, or by some adorable Beagles. Australia will issue serious fines immediately upon the finding of an undeclared product.
Yes, it’s true that Hawaii has some safeguards like this, but the enforcement is extremely lax. Never have my bags been screened and no officer reads your declaration before letting you enter. Lame.
