Just to clarify......i brought over a Laptop & a portable media device in my hand luggage & was asked the age & value of both as i passed through Adelaide customs. I informed them they were both a couple of yrs old.
However i sent over a bag of Unaccompanied luggage & declared on the Customs form that 2 of my Kitesurfing kites were under 12 months old, to which they presented me duty charge of about 100 bucks.......Welcome to Australia !!!!
