Peter Letts
Founder of Abyss Scuba Diving and PADI Course Director
With a passion for transforming nervous first-timers into confident divers, Peter Letts has played a key role in shaping diver education in Sydney since the 1990s.
Peter learned to dive in Cairns in 1992. Originally a very nervous diver, he overcame his fears and quickly became addicted to the sport. He completed a wide range of courses, becoming a Master Scuba Diver and then a Divemaster. He worked as a Divemaster for several years before becoming an SSI Open Water Instructor in 1996 and crossing over to a PADI Open Water Instructor in 1997.
In 2000, Peter left the corporate world and opened Abyss Scuba Diving in Sydney. He started the business with his daughter, Rachael Fallon, and the first diver he ever trained, Kellie Oldfield.
Driven by a vision to build a world-class PADI dive centre, Peter implemented global best practices and worked tirelessly to establish Abyss as one of Australia’s top training facilities.
In 2008, Peter travelled to the USA to become a PADI Course Director. He later contributed to the development of PADI eLearning and was a pioneer in using social media to promote scuba diving. Peter has represented the dive industry at major trade shows and corporate events.
In 2021, Peter was honoured with the Australian Underwater Products "Legend Award." At that time, he stepped down from daily operations, passing leadership to his daughter Rachael. His legacy continues through the dive centre’s commitment to excellence and innovation.
