We have always been known for our no nonsense approach to providing dive facilities and instructors
with good service, sound advice and superior teaching materials provided at an excellent value. Change in the
diving instruction business has traditionally been a slow process with few of the established agencies willing to
be “first” with any departure form the “old way of doing things”. We led the acceptance of modern technical
programs with TDI and continue to do the same in traditional scuba training.
Currently TDI offers courses in Entry Level and Advanced Nitrox, Intro to Tech, Extended Range
(deep air to 180 fsw / 55 msw), Entry Level and Advanced Trimix, Decompression Procedures, Rebreathers
(Semi-Closed & Fully Closed), Overhead Environment (Wrecks & Caves) and technician training for
equipment servicing and the blending and mixing of gases. TDI was the first to offer a fully developed training
program for rebreathers and hosted the first ever instructor trainer workshop for that equipment in June of 1995.
Since our introduction in Australia in 1994, the year Technical Diving International was formed, we
have continued to strive to lead the local market. Our instructors were among those that attended the first ever
Rebreather Instructor course in 1995 and we were integral in pioneering the OZTeK Conferences and Dive
Shows, starting with the first in 1999. We lobby Standards Australia as a representative voice not just of our
members but for the entire Recreational (Sport & Technical) Dive Industry. We maintain ties with State
Workplace departments and other regulatory bodies and are active in Dive Industry initiatives. We are a fresh
voice with new ideas who listens to what our members and divers tell us.
Nitrox Diver
This is the entry level certification course for recreational divers wishing to utilise enriched air nitrox
(EAN) as a breathing gas. The objective of this course is to train divers in the benefits, hazards, and proper
procedures for using nitrox mixes from 22% to 40% oxygen content.
Intro to Tech
This course is designed to familiarize students with technical gear configurations, to enhance open
water diving skills (such as buoyancy, trim, and situational awareness), and to introduce students to advanced
gas planning techniques within a no-decompression context a maximum depth of 75 fsw / 26 msw. This course
is strictly a no-decompression course; students are permitted to use Enriched Air Nitrox mixes, provided the gas
mix is within their current level of certification.
Advanced Nitrox Diver
This course examines the use of EAN 21 through 100% (oxygen) for optimal mixes to a depth of 130
fsw / 40 msw. The objective of this course is to train divers in the benefits, hazards and proper procedures for
utilising EAN 21 through 100% (oxygen) for dives not requiring staged decompression.
Decompression Procedures Diver
This course examines the theory, methods and procedures of planned stage decompression diving. The
objective of this course is to train divers how to plan and conduct a standard staged decompression dive not
exceeding a maximum depth of 150 fsw / 45 msw, unless taught in conjunction with the TDI Extended Range
Course. The most common equipment requirements, gear set-ups, decompression techniques and optional
decompression mixtures (including oxygen and nitrox) are presented.
Extended Range Diver
This course provides training and experience required to competently utilise air for dives up to 180
fsw / 55 msw that require staged decompression, utilising nitrox mixtures or oxygen during decompression.
The objective of this course is to train divers in the proper techniques, equipment requirements, and hazards of
deep air diving to a maximum of 180 fsw / 55 msw.
Advanced Wreck Diver
This course provides training and experience to competently conduct advanced wreck dives. This
program includes penetration skills and techniques. The objective of this course is to train divers in the proper
techniques, equipment requirements and hazards of wreck penetration diving.
Nitrox Gas Blender
This course provides the training required to allow candidates to competently and safely blend nitrox
gas. The objective of this course is to train candidates in the proper techniques, equipment requirements and
hazards involved in blending nitrox gases for recreational scuba.
Advanced Gas Blender
This course enables the successful candidate to engage in the preparation of high quality scuba gases.
The objective of this course is to train candidates in the proper procedures needed for the preparation and
blending of high quality gases including nitrogen, oxygen & helium mixtures.
Oxygen Service Technician
This course enables the successful candidate to engage in the preparation of scuba equipment for
Technical Diving Gases. The objective of this course is to train candidates in the proper procedures required
for oxygen equipment cleaning.
Technical Divemaster
This program is designed for Divemasters from other recognized agencies wishing to join as TDI
Divemasters. Once the candidate has successfully met the requirements as a TDI Divemaster they will have the
same privileges as a TDI Instructor at that level. The TDI Divemaster is a leadership rating for dive operation
supervision and to assist in training where allowed. The objectives of this course is to train Divemasters in the
supervision and leadership of divers undertaking Technical dives and Training.
