If you put any value of over $1000 Aud be it the declared value or insured value or both then our customs will hold the item for ransom. There is a lot of hidden fees to pay if the magical $1000 is exceeded. I have tried to explain that the detectors are to be sent back to the customers but it falls on deaf ears. Our Government insists that we are the lucky country, but with anti business tactics like they have i call it the stupid country. I have looked into various ways to overcome this stupid system but i would be caught up in hours of paper work, lodging bonds, and more government fee's. I will put up some more info as time permits.
