David Marinakis
Brazilian Jiu Jitsu Coach (Black Belt 2nd Degree)

“I got introduced to BJJ back in 2003 after watching the early UFC’s and Gracie in Action tapes (you can still find some of these on YouTube). Basically these tapes showed these smaller statued Jiu Jitsu guys defeating all these larger opponents from other martial arts backgrounds. I felt like I had stumbled upon the holy grail of martial arts! I was looking for something to train in and wasn’t interested in doing Kata’s or ‘Forms’.  I wanted something more real, practical, challenging, and Jiu Jitsu met that need for me. In 2005 when I found the right training environment, I fell in love with Jiu Jitsu and never looked back.”

BJJ Accomplishments:

“My proudest accomplishments to date have been representing Australia twice at the ADCC Submission Wrestling World Championships in both Barcelona, Spain and Nottingham, UK where I got to compete with 2 of my idols, Rubens ‘Cobrinha’ Charles and Leo Vieira.

I have also qualified twice to represent Australia at the World Pro Jiu Jitsu Championships held in Abu Dhabi, bringing home a bronze medal in 2011, Brown & Black belt division.

In 2015, I completed a 10 year goal of winning a State and Pan Pacific gold medal at every belt level when I won the Victorian and Pan Pacific Championships at Black Belt. I won this again in 2018 along with a Silver medal at the 2019 Asian Open in Tokyo, Japan.

Coach Lee and myself both teach the BJJ classes at Immersion meaning there’s 2 black belt coaches on the mat every night! We’d love to have you join us so we can share our Jiu Jitsu with you.”

‘Competition to me is pure, you can’t fake your skill or talk it up. It is what it is. It also teaches you how to handle pressure and how to deal with defeat and success, it will make you stronger’. Lee Ting

Lee has a dynamic teaching style bringing serious training with a bit of play and laughter. Lee is always trying to bring out the best in his students, both mentally and physically. This also transcends through other facets of their lives also.
