Hello Blue
That wasn't too hard, I just asked about the free trade agreement with the US of A, the pencil pusher realised straight away that he was wrong and said " oh, that shouldn't have been charged " yeah right, you would think that these public servants would know how to do their job but it needs a dumb schmuck to tell them, if I was syndical I would think they saw it as sport to get as much as they could from the general public.
As to if you can expect it or not, in theory, all parcels coming into the country are liable to have charges against them including GST, however, generally if the value of the goods are <$1000.00 then customs appear to leave you alone. If the goods come in from countries other than the States and we don't have a free trade agreement with them then duty could be payable as well, ( even ftom the States, if the goods are not substantially manufactured then duty is payable on them as well )
I think what is happening though is the volume of goods enetering the country is now so great due to Ebay and others, that the customs service is swamped.
As an example, I have bought in Nema 23 size steppers from the States in the past ( thanks woody ), 6 will fit into a 20 pound box from Elwood, the steppers will cost me about US300.00, Woody is another US$60.00 ( ish ) so id GST was levied on the steppers the AU gov' would get about $37.00. now if it was a gift then no GST is payable, the customs declaration would need to be read, a form filled out, sent to me, paid and collected, the collection would be done by Aust Post, who would then have to send it to customs, all for $37.00, would you do that if you were trying to maximise profits?
Bear in mind though that if you have to pay GST, then the goods you buy he will also have had GST charged on them so you are not any worse off.
Sorry for the long winded reply.
here are other ways of bringing bulky / heavy stuff into the country but since I'm thinking of selling linear rails of hobbyist cnc'ers you'll have to work that out for yourself/s.
