Tourist bureau or Ash/Kylie at adventure tours. Grahame @ Cocos Castaway would be the best bet. Seems we were lucky that our planes were on the days scheduled (but any excuse to tell the boss I was stuck on Cocos would have been nice). Pray for another volcano eruption on Bali and you will have a few more days to consider. cauncy is right. You could wade to pula maria (feral chook island). There is a lean to there and plenty of coconuts (and chooks).
