Well so are NZR , but thats only for the Drua, they will need a shit load more money than part of a sports grant to Fiji from Aus gov't , a few hundred grand a year from NZR and a bit from WR (World Rugby) (World Rugby). They will need NZR and Rugby Australia to throw in a bit to get them on feet properly. Unless they get a generous billionaire ro something.
Personally would be in raptures if Japan and Fiji joined, but finance is a huge part of it, Japan wouldn't have a problem I wouldn't think, but much as I hate to say it I doubt whether Fiji can afford it?
