Hi Kite!
You have made a good choice with BNE (if you indeed had a choice this time) - great weather, and a good base with crew who have been around for a while in general.
I have just returned from exchange number 3 - had a ball over there!
Most Atlantic crew seem to gravitate to the New Farm, Teneriffe, Newstead or Fortitude Valley areas as they are close to the nightlife, cafes/bars and public transport to get you out to the airport. They are a little more expensive, but you are only here for a year, and compared to London prices - it is cheap!!
See you soon!
