Inside was about 30 Grey reef sharks, a few Whitetip reef sharks, a Tawny nurse shark, three green sea turtles and a ridiculous amount of fish... all crammed in a hole only 80 metres wide.” Sounds like a busy spot! 😉 Book a scenic flight over the reef with @gbrhelicopters or @air_whitsunday and you who knows, you might even spot interesting geological formations like this from the air yourself! #seeaustralia #thisisqueensland #greatbarrierreef #explore #travel #wanderlust」4月29日 4時00分
