引用： Goods with a declared or assessed value not exceeding A$1,000
If your goods arrive in Australia by mail and have a declared or assessed value of A$1,000 or less, the goods may be imported free of duty, taxes and Customs and Border Protection charges, unless they are alcohol products or tobacco products. Apart from alcohol and tobacco products those goods will be cleared by Customs and Border Protection and delivered by Australia Post without you doing anything.
Goods with a declared or assessed value over A$1,000
You will be sent a First Notice by Australia Post if you have imported goods with a declared or assessed value of more than A$1,000.
In this case, you need to lodge an import declaration to Customs and Border Protection for the goods. The declaration will be assessed for duty, GST and Wine Equalisation Tax (if applicable). An import processing charge will also apply. Customs and Border Protection will advise you of the amount you need to pay before your parcel will be delivered to you.
Customs and Border Protection cannot allow goods with a value over A$1,000 to be delivered by Australia Post until an import declaration is made and any liability for duty, taxes and charges is paid in full. There may also be AQIS requirements to be met before Australia Post can deliver your goods.
