I ve rang customs ,duty free and the air port and no one knows if we can buy duty free in Adelaide then fly to Melbourne and go thou all the security checks with our 'sealed' bag of a bottle of gin ,cigs and perfum and get on our international flight. What a bunch of dimwits!!!!!!! I know the regs. re 100mls etc but I thought that if your bag was SEALED you could travel with it.Question how can duty free shops in citys sell you boose etc if you cant take it with you PLEASE HELP ....... Im confused
