Matt, sorry looks like i'm no help yet. This is the reply i got from my friend.
hello mate - how are you - all good here - The barrier reef is a long way from here - but by all means share my email - I am in kakadu territory! Cheers Steve
Lol, as you can see he is a short and sweet kind of guy. I told him i wouldn't pass on his email, but now i'm thinking why not. More options never hurt anybody.
lol, i'll get it. steve.mcgugan@ntschools.net>
Heh, just realized in the earlier brain-snap moment i had him in Cairns instead of Darwin.
Anyway, just now in searching for a map with cities on it i could copy i've been to a number of places. Here are a couple of them.
Reefs Around Cairns This map shows the Great Barrier Reef, and identifies the major reefs visited by the multi-day liveaboard dive boats operating out of Cairns and Port Douglas.
