...and Customs 'inspection' fee (or some such thing). Ican't remember the eact details but I got stung on what appeared to be a cheap import.
According to the cutoms/tax guy at the time, the threshold is $1000 AUD (on the total cost, including shipping costs) if it's 'ordinary post', but if it comes by Fedex (or other carriers) the threshold is $300 AUD. After that, customs want to know what's in the box, and they charge a fee for loooking/asking - I think it was something like $150 - so my $400 import ended up costing about $600.
The moral of the story is: if it is less than $300 (or $1000 if you can wait for 6 weeks seafreight) you probably won't pay anything at this end, but if it's over, add on GST, duty and customs


(leaving aside any 'fraudulent' shipping documents)
