Joyce Samuel

Independent Assistant Instructor

Joyce never anticipated scuba diving would become her passion, especially since she once feared snorkeling. But everything changed when her husband suggested they learn to scuba dive and explore the Great Barrier Reef. After several months of training—where clearing her mask was a real challenge—she finally achieved her goal. In September 2019, they took their first ocean dive off a liveaboard in the Great Barrier Reef, and Joyce was instantly hooked! Now an Assistant Instructor, she’s eager to keep learning and share her love for diving. Joyce proudly identifies with the “80-80-80 club,” enjoying dives in warm waters (around 80°F), warm air above 80°F, and visibility of at least 80 feet. Her favorite dive spots? Anywhere she can blow bubbles and explore the wonders below.
