$450Who teaches you
I'm Paul Gammer. I've been diving since 1998, teaching since 2010, teaching TDI technical courses since 2013 and the Poseidon rebreather since 2014. I'm a PADI Master Scuba Diver Trainer and an SDI, TDI and RAID instructor.
I keep groups small because that's how people learn properly. If you want a course 1:1, just ask.


Where we dive
Confined water sessions run from the Perth Diving Academy facility in Hillarys. Open water dives are around greater Perth, from Rockingham up to Mindarie, and often from PDA's boat Wildcat in the Marmion Marine Park.
