Hi All,
Well I have looked into this a little further and looks like, If I am reading this correctly there is not 5% tariff on Astronomy gear.
http://www.customs.gov.au/site/page.cfm?u=4273
See Schedule 3 - Chapter 90 Notes - (search for 9005 in this pdf)
http://www.customs.gov.au/webdata/re...ter90notes.pdf
then look up 9005 in this list of tariffs.
"Goods - 9001 to 9021.10.20"
http://www.customs.gov.au/webdata/re...r90goods_a.pdf
Note its free.
However I belive GST would still applied on items above 1000$, This is applied on the price + shipping/handling + insurance.

Fahim
