GUFF is the Get Up and Over (or Going Under) Fan Fund which transports SF fans from Europe to Australasia (and vice versa).
This year, a delegate is to be selected to travel from Europe to Australia and/or New Zealand. Voting is open to anybody who is active in fandom. There is a competition this year, so take the time to see which of the worthy candidates you would like to bring down under.
All you need to know about the candidates and voting can be found over at the ozfanfunds site.
