Sad to say, you're dream will never happen.

1) The great barrier reef is dying due to global warming. You might want to hurry up before it all dies and becomes just dead coral.
2) Because its dying, there are already alot of limitations on it. I highly doubt they will allow underwater construction next to it.


Me? I'm an internet troll. I roam around forums making snide witting retorts and I get paid in the tears and whimpers of my victims.
