Jdsk posted his link while I was typing and the current limits appear more generous than they used to be
They are a lot more generous. It is now 7 cases of 25cl dumpy beers. It used to be one or two I think. Much more wine as well - about 25 bottles.
Fags still at 200, although this was criticised by health campaigners. For Australia (and maybe other countries) there is no duty free allowance for tobacco products. They are not allowed to be imported.
Self use, but giving as a gift is allowed
By the way, the link above has a rogue x at the beginning.
