About
Paul Gammer
Diving since 1998, teaching since 2010, and teaching technical and rebreather courses for more than a decade.
I run Roleystone Diver Training from the Perth hills. It's deliberately small: I teach every course myself, in small groups or 1:1, so the course moves at your pace.
Most of my teaching now is technical and rebreather training. I've been teaching TDI technical courses since 2013 and the Poseidon rebreather since 2014, and I'm one of very few instructors in Western Australia who is current on the Poseidon. I still enjoy teaching new divers, though, and the recreational courses are where many of my technical students first started.
