Yes, and PET containers don't leak or get broken in the suitcase (and believe me , baggage gets rough treatment) , and the 1kg saved means I can bring more shopping back. The malt Scotch goes into a glass decanter when I get back , and does not suffer in plastic.
I always make truthful declarations - and to date the customs guys just wave me through - its not worth their bother.
Yes, and at the end of the day will only carry my legal entitlement in - or a tad more. I also believe opening the bottle, or transferring it to the wrong container - this process marks the contents as 'condemned' and has a zero duty rating , but still liable for excise on alcohol content. (plus GST). If this amount is less than $50 or some magic value that they don't tell, 99% of the time , they just wave you on. I have also declared a handful of miniatures over the limit, and also waved on.
I suspect customs officers are looking for the ones who are in on the resell racket, or attempting to deprive the local DF shops - busting Britons with 6 weeks worth of smokes from Dubai seems common, while the others would rather catch a drug mule, or someone with undeclared food.
As for the Airport DF Shops - believe me they are suffering big - the rent is killing them, the GFC has made a little dent,
but now the price of so many goodies is under $1000 - direct online shopping is also cutting into Camera lines and the like.
I suspect their buy price is higher than their American counterparts. Volume static, rents up, costs up, price of electronic gizmos down. I suspect they are preying for the liquids rule to change, or SACL to show mercy on the rent side.
The Australian DF Shops have now earned a reputation for being expensive (and HK) , Changi and BKK are happy to
take the money, if even only slightly cheaper. Personally I think their range is coughpy and limited - not a patch on Dubai.
Combined with first impressions (at the airport) , I am not sure if Australia 'gets' the tourism experience.
