Marine Biologist reef conservation work

Our team of dedicated Marine Biologists are actively engaged in conservation work on the Great Barrier Reef. Their weekly tasks include collation of data via observational surveys as part of the Eye on the Reef program with the Great Barrier Reef Marine Park Authority.

Meet our Marine Biologists:

Phil Scott, Marine Biologist and PADI Dive Instructor

Phil graduated from James Cook University with a Bachelor of Science, majoring in Marine Biology. Phil joined the Down Under Cruise and Dive team in August 2018, working onboard Evolution as a marine biologist and PADI Dive instructor. Phil runs the snorkel tours, showing visitors our reef sites though engaging educational tours in the water and also through speeches on the semi-submersible vessel.

Phil also conducts our Cairns Educational Tours for high school groups onboard Evolution, with who we involve in data collection through the coral-watch program run by the University of Queensland. He is also involved in the Eye On the Reef tourism weekly program, where data is collected weekly from our dive sites.

Phil is passionate about helping people fall in love with the reef like he has, and to ignite passion in others through high-quality education so that we can maximise the chances of a functioning reef system in future uncertain times.
