In Australia, 'cheers' is used by acquaintances or in inter office emails. A woman can also tell that a man is not interested in her romantically if he signs off 'cheers, catch you later'

Hi Lisa I think Alaric is right - its a typical English word. Used more often as another way of saying 'thanks' in an informal way, but can also be used informally - the nearest equivalent I can think of is 'all the best'. In my experience, it is not common as an e-mail sign-off.

I wouldn't say it is common but it's not so unusual. It is only likely to be used between friends and I believe that it's more common in the UK than in the USA.

In the US, we only say "cheers" when we're drinking. :) For Brit/Irish/Aussie version of "cheers" we'd only say "thank you/thanks", as far as I know. =)

Yeah, in the US, that is not a term that someone would use at the end of a text. It sort of makes sense, but it's kind of weird.
