Known locally as ‘Diver Di’,    Diana Doreian qualified as a diver in 1993, and then certified as PADI Divemaster & Instructor in 1997 soon after returning from Japan for her 1996 ‘gap year’ learning the culture & language.

Following this she spent many years working with introductory diving on the Great Barrier Reef, giving divers their first ever ‘Discover Scuba Diving’ Experience, along with Learn to Dive courses. After stints working on resort islands, some time as a Japanese speaking rainforest guide, plus some underwater videography, she returned to teaching scuba courses and running dive centres, continuing her personal diver education to IDC Staff Instructor, and assisting Instructor Training programs.

Later moving to Brisbane, and discovering the local dive scene, she found much satisfaction in finding new outdoor hobbies, mountain biking, rock climbing, camping & hiking, whilst working for outdoor adventure stores & scuba equipment wholesalers.

Later working as an independent PADI Instructor assisting Go Dive Service Centre with their logistics, running personalized training courses, international & local dive travel.  A fulfilling but very busy schedule, with the wide range of ‘day jobs’ keeping her on her toes and fast-paced at times.


Schedules can be tricky sometimes. often juggling between the bespoke programs requested by scuba, along with four overseas trips a year and local diving & some charity events, she tries to navigate everyone’s times to the best and most productive results!

Diver training

Working together with up to five dive companies, SubmersibleHumans training programs aims to give students the best of all flavours possible, when it comes to skills, experience & training.

From this type of training she is developing very well rounded, confident divers, who benefit from courses planned to their schedule, as well as an instructor who is focused on their personal development of a diver as an individual, not as a group of 8 or sometimes more.

Local Diving

SubmersibleHuman is now building a Dive Club – Dive Tribe Brisbane with a group of committed PADI Professionals – to give divers oppertunities to socialize and dive with local buddies.

International Dive & Snorkel Travel 

On average, three to four overseas trips, and two national trips are planned each year, with a range of trips for snorkelers, novice divers and more experienced divers to enjoy a holiday joining a group of like minded travelers, without needing to ‘mind the details’ too much, with SubmersibleHuman tidying up the details & schedules.

In 2018, Di celebrated 22 years as a PADI Professional – Divemaster & Instructor. As a tribute to her original Course Director, a ‘Thank-you John’ video was created:
