 Cairns Live-Aboard (By

 Shortly after getting our Open
 Water certification, we decided
 that it would be good to go away
 on a holiday where we could ex-
 cersize our new freedom. After
 doing various searches on the
 internet, we found that one of the
 best financially beneficial ways
 to do this was to go on a Live
 Aboard at Cairns. (We did the
 calculations on how much it
 would cost to do day trips, and
 pay for accommodation, meals,
 etc back at Cairns vs a livea-
 board, and the liveaboard came
 up best).
