Duty is not GST. Duty on alcohol depends on the alcoholic content - so for example on Gin it is 5% + $68.54 per litre of alcohol (based on the alcoholic content of the gin), plus GST.
Which is why duty free alcohol is so much cheaper then non-duty free.
Cigarettes also attract a high duty.
For other items, such as watches, the duty is only 5% + GST.
