Maverick Day is the Head Coach of Muay Thai and the founder of the Top Gun Muay Thai affiliation. In 2017, Maverick relocated from Cairns to Brisbane and in the spring of 2022, founded Ground Zero Gym together with Gürkan Baydogan.

Since Maverick could walk, he has been immersed in Muay Thai, thanks to his father, Ronald Day (Ron). Mavericks’ family owned and operated the Cairns Quest Centre, where Ron was the Head Coach and is one of the most renowned Muay Thai coaches in Northern Queensland. Since Maverick was four, Ron has been an inspirational mentor, paving the way for Maverick to compete professionally and pursue coaching as a profession which began at 16 teaching the Kids Comp Classes at his family’s gym.

In October 2022, Maverick made his mark in Australia as one of the youngest coaches to mould a student into a competitive fighter winning the 2022 WBC Queensland Championship (Female Featherweight).

His achievements as a coach didn’t stop there. Not only has Maverick had a Level 2 National Accreditation since 2018, he has also competed as a Muay Thai fighter at the kid, teen and adult levels, fighting against some of Queensland’s best fighters. On top of all of these achievements, Maverick accomplished all of this before he was 22.

Gürkan Baydogan is a Brazilian Jiu-Jitsu (BJJ) first-degree black belt (IBJJF Certified) under Tito Beltran of Crazy Team. Originally from Berlin, Germany, Gürkan moved to Brisbane in June 2021, and in the spring of 2022, co-founded Ground Zero Gym with Maverick Day and is the Head Coach of BJJ and NoGi.

For nearly 30 years, Gürkan has been involved in martial arts beginning with Wing Chun Kung-Fu and Muay Thai, and then went on to discover grappling resulting in him opening one of the most prominent and renowned martial arts gyms in Berlin – Spitfire Gym in 2013. Since opening Spitfire Gym, Gürkan worked extensively as a grappling coach and an MMA fight manager for various competitors and champions who competed successfully across Europe and worldwide. In late 2019, Gürkan sold Spitfire Gym to one of his students after relocating to Spain, where he joined Crazy Team and could dedicate more time to advancing his grappling skills.

Not only is Gürkan a highly technical coach, he is also a high-level competitor, winning multiple championships throughout his BJJ journey that continues to this day.
