Yesterday in the Great Barrier Reef!!! After spotting this deep blue hole on google maps we decided to head far offshore, out further than our normal Reef trips to see what dwelled within. What we found inside was hard to believe considering 5 months ago a Cat 4 cyclone went straight over the top of it. At around 15m - 20m deep there was huge Birdsnest Corals (Seriatopora) and super elongated Staghorn Corals (Acropora) both of which were among the biggest and most delicate colonies I've ever seen. Totally unaffected by the cyclone. The position of this deep hole within the lagoon walls has obviously protected these corals for decades. We may very well be some of the first to dive this deep hole as it was hidden within one of the Great Barrier Reef's biggest lagoons...
