We took BobMacs advice, but took 2 x 4 litre casks and had no problems, we drank one and a half and gave the rest away to a couple of aussie women in our hotel.

But alcohol is really pretty reasonable now, 20 years ago the only aussie wine we saw was 'Spritzig Rose' which sold in Perth for about $6 a bottle but cost $25 in bangkok. Beer is cheap.
