Welcome to IANTD Australasia.

IANTD was the first agency that offered training in all aspects of EANx through continuing education programs. This allows you to expand your knowledge and training with the top professionals in the field..

IANTD instructors are well trained, highly experienced and extremely qualified. IANTD Standards and Procedures provide for the highest level of EANx education and training available from Snorkelling through to Trimix and Rebreathers. IANTD now offers E Learning courses that are available through our Facilities and Instructors.

Please check our Facility Listing to find your closest training location.

IANTD (IAND, Inc.) was founded by Dick Rutkowski, the former dive supervisor for the National Oceanic and Atmospheric Administration (NOAA). Mr. Rutkowski introduced the recreational diving community to the technology of EANx. This program was developed through NOAA during his tenure. Today the board of directors and the membership of IANTD are composed of many of the most experienced divers in the world pertaining to the use of breathing gases other than air..

IANTD was one of the first International dive agencies to offer a certification program in Enriched Air Nitrox, the company was kept at a slow, yet steady pace from 1985 through February of 1992 with the support of Hyperbaric International. In 1991 the late Tom Mount joined Dick and IANTD became the FIRST to offer training programs in all aspects of technical diving (Advanced Nitrox, Deep Air, Technical Diver, Cave and Wreck Penetration, Normoxic Trimix, Trimix, Expedition Trimix, Rebreathers, etc.) and now Free Diving too! .
