Established in 1999 as The Australian Diving Technologies Conference & Rebreather Forum, OZTek has rapidly evolved, gaining in stature and international recognition to become one of the leading events of its type held anywhere in the world. Focused on the latest developments in diving and the technology used by underwater explorers in their bid to unlock the ocean's secrets, the OZTek Symposium has become synonymous with diving excitement and adventure.

Building on the success of the previous nine events, the OZTek017 Conference will once again feature an international cast of speakers - each an acknowledged expert in their respective field of diving expertise - to enthrall, educate and entertain.

"In my professional life, I have the opportunity to participate in and attend conferences in a range of subjects in USA, Europe, UK, Asia, China and here. OZTek was genuinely of world standard in pretty much every way. The speakers were better than all other conferences I have attended and the venue was great. "
