The OZTek Awards celebrate the achievements and endeavours of Australia's leading Divers and Dive Industry personnel - the people who have helped push the boundaries of knowledge and exploration in the field of advanced and technical diving.
On Sunday 15th March 2015, during the Gala Award Ceremony, previous OZTEk award winner Dr Richard 'Harry' Harris announced OZTek's 2015 Outstanding Achievement Award. This is what Harry had to say to packed audience of advanced and technical diving movers and shakers.
"It is an enormous honour to be asked by the OZTek Organisers to present this very well deserved award to a close friend, a wonderful dive budy, a mentor and a constant voice of reason in the mad world of technical diving!
I would like to break with tradition and ask this man - John Dalla-Zuanna - to come and join me up here, whilst I tell you why he is such a special guy in this great sport of ours.
At the cheeky young age of just 58, JDZ is truly a veteran of the sport of cave and technical diving. Cave diving in Australia started pretty much at the time JDZ started cave diving, so it is impossible to consider one without the other. Around the time the CDAA became incorporated in 1973, JDZ started visiting the Mount Gambier area. He cut a fine figure in Piccaninnie Ponds with his Moray suit! He became qualified in 1975 as member #256 and from that time on was inspired by the sport. A trip in the late 70's to Florida to meet Sheck Exlley, Wes Skiles and Woody Jasper quickly led to adopting sidemount diving, and feeling the thrill of laying line in virgin passage.
Thus the passion was born and returned to Australia and began teaching both open water and cave diving. He has reached the highest levels of recreational and cave diving instructor. And, as a long time FAUI instructor, a PADI Course Director and CDAA Advanced Cave instructor, countless students have come under his thoughtful and methodical influence. The CDAA has benefited enormously from John's vision for cave diving, and he has filled a voluntary position with that organisation in some form or another almost continuously. Ken Smith always said that he used to think cave diving politics were a matter of life and death, and now he realises it is much more serious! JDZ has been a calming influence on all factions of the CDAA for many yearss and is unique in that he is respected and heard by all sides.
I met John at OZTek in, I think, 2003. We had been exchanging emails for awhile and I was about to leave to live in Vanuatu. John had built a rebreather heads up display from an LED light and a mobile phone vibrating motor! He generously gave me this device to put onto my KISS rebreather, which considerably enhanced the safety of my cave exploration at the the time.
After my stint in Vanuatu JDZ was one of the instructors on my penetration course and we struck up a real friendship underscored by our passion for caves, rebreathers and exploration. John had dived in so many caves around the world and along with guys like Paul Hosie, Craig Challen and Ken Smith, I quickly found a group of experienced cave divers who mentored me into the world of exploration and expedition diving. I am sure John has had a major impact on many other peoples' lives, the way he has influenced mine.
JDZ's ingenuity goes way back. He built a radio detection device called 'the Thumper' which played no small part in the mapping of Mount Gambier's showpiece, 'Tank Cave'. John was an early adopter of closed circuit rebreathers, and along with Tubby McKenzie the early leaky valve CCR Dolphin was born and dived to 85 metres on the Bayonet in the ships graveyard in Victoria. It was this creation that caught my eye and got me into rebreathers in 2002.
John the inventor became an indispensable part of the Wetmules team. (Moto: Lurching from crisis to crisis). His lithium scooter batteries propelled Craig Challen and I to the end of Cocklebiddy in 2008, where Craig added new line to the end of the cave. They also now famously caused the fire which burnt my car to the ground on the way home! His early 12 volt heated undergarments kept us warm in the Pearse Resurgence and his wonderful pasta kept us fed.
John is a regular ocean and wreck diver. He has numerous sub 100 metre / 328 feet wreck dives to his credit and continues to teach young divers open water diving through the La Trobe university club, sharing his passion for all things aquatic. His huge passion right now is the 3D mapping of cave using a combination of video and gaming technology, and in this area he is becoming a world leader. I hope many of you got to see his talk on this today. As the current Site Director of CDAA he shows no sign of letting up, and I look foward to sharing many more dives with this wonderful friend and great ambassador for the sport of technical diving.
John Dalla-Zuanna, please accept this Outstanding Achievement Award for your long standing contributions to cave and technical diving."
