Fascinating thread, I just had to dip in.
So in chronological order:
Vancouver (Open Water dives at Whytecliff Park)
Red Sea (Northern region from Hurghada-based liveaboard)
Whitsundays, Australia
Northern Great Barrier Reef and Coral Sea from liveaboard
Vanuatu - Espiritu Santo (President Coolidge)
Fiji - Kadavu
Fiji - Off Viti Levu
British Columbia - Howe Sound
England - Wraysbury Lake (doesn't count; it's a reservoir near Heathrow airport)
Gozo
Definite plan in the next six months:
Return to Australia
Possibly:
Southern Red Sea
Hopefully:
Papua New Guinea
Micronesia
Scapa Flow
