As far as checked baggage, you don't need to worry about liquid restrictions. The rule of 100ml is for carry on. The rules as far as what you can/can not carry apply to the country/countries themselves, not the airlines. Here's a link where you can find info re liquids, aerosoles and gels,plus there's other info about restrictions for what you can carry on board http://travelsecure.infrastructure.g...nal/index.aspx

Some people do lock their bags, or get them vacuum sealed shut in plastic at the airport, but personally I don't see the point. If someone wants in your bag, they'll get in your bag. They'll be smart enough to break the lock and then replace it so it's really only something that is done for your own piece of mind.

As far as staying in contact, we made sure we turned off international roaming to avoid being slugged with huge fees, and then bought a pre paid sim card when we got OS and just used that. We took cash out each day or two, just enough to last us for the next day or two. Where we could we used CC aswell. A friend is currently in the states and she uses a travel credit card (with ANZ I believe but I think all banks have them now) which she uses like an atm/cc. The only reason she does it is because it stays locked at the exchange rate when you put money on the card so she could start putting money on it 6 months ago and then not have to worry about the $$ plummeting while she was over there. This isn't something you should have to worry about going to Fiji though. If you can get onto the internet, you can certainly do internet banking.
