不清楚你去那州?每个州的law会有点不同,但都有smoke free zone,多数有4 or 5m的law--距离exit 是no smoking区。
如果我沒记错, duty free shop是位於在海关之前,所以duty free是只限於下面的数量: http://www.border.gov.au/Trav/En ... -or-Cigarettes-Back
不然超过数量:
If you bring in more than your duty free allowance for tobacco and cigarettes, you’ll need to pay duty on all of your tobacco and cigarettes, not just on the excess.
