In Reply to: Duty Free should be LEFT in Perth posted by Glenda on Sunday, 29. April 2012 at 07:43 Bali Time:
Anything bought duty free in whatever country has to leave that country. Bringing things back or taking them into another country has a totally other set of rules without particular limits to each country. You don't have to consume your alcohol overseas but you can only import 2.25 litres into Australia regardless of it being purchased duty free or not.
