Carlton Draught is a pretty good beer (for those who are adults of course). But even if you aren't old enough to have alcohol you should be able to enjoy this ad. Its very funny, quite Australian in its feel (without making us Aussies groan) and would have cost a lot to make. This is definetly one of the better ads on in Australia.
I would rate this trailer PG for two swears.

Enjoy, and remember (if you are old enough) to drink responsibly.
(The Aged 18+ rating in the corner of the screen doesn't mean its explict but that's the legal drinking age in Australia and its required to be there by law.
