GUFF is the Going Under (or Get Up-and-over) Fan Fund which transports SF fans from Europe to Australasia (and vice versa).
Nominations in the race to send a European fan to Worldcon in Wellington, New Zealand (29 July-2 August) are open to anyone who was active in fandom prior to January 2018.
Depending on the length of trip they’re able to make, the winner could also consider visiting other parts of New Zealand and Australia to visit fans. The winner will also be required to take over the administration of the fund for the next northbound and southbound races.
Lots more information is available on the Oz Fan Funds GUFF page. Even if you don’t wish to run for this yourself, give some thought to who might be a suitable candidate – perhaps you could offer to nominate them.
