My husband and I, both divers for 20+ years, will be in Fiji in January 2011.

Any recommendations on diving in Fiji? We'll be staying on Denarau Island. I know that there will be diving of some kind almost everywhere, but any suggestions on don't miss spots? From Denarau, is it feasible to travel by boat very far to dive sites?

We will be there in January, 2011 -- does Fiji have jellyfish issues like Australia that time of year? Any other hazardous issues to be aware of?

Also, any suggested tour operators?
