NUCA is based on the Sunshine Coast in beautiful South East Queensland. Our SMART Urban Combat System was developed as a means of providing self defence training to meet today's needs. At the foundation of our style are techniques from Okinawan Goju Ryu and Zen Do Kai as well as Brazilian Jui Jitsu and Muay Thai. The system was created as a result of an obvious need for a street system as opposed to a sports style martial art.

We are a Black Belt Academy.

What's the difference?

Our Black Belts are Earnt, not bought.

Black Belt training courses. Learn the secrets of GoJu Ryu karate as taught in the birth-place of karate, Okinawa.   This traditional combat system was developed specifically for unarmed combat as opposed to many sports style karate.

Muay Thai.  Our system incorporates Thai style fighting.  This system blends perfectly and extends the effective combat capabilities by incorporating the use of elbows and knees. Ideal for close range fighting. 

Ground Combat.  Our system also incorporates Brazilian Jui Jitsu for those occasions when the fight ends on the ground.  The NUCA system has been developed to include techniques for all situations.

Women's Self Defence. NUCA is ideal for Women of all ages and we have incorporated training techniques that are specifically suited for women’s self-defence and rape defence.

Weapons.  NUCA trains in a variety of weapons.  We study Okinawan Kobudo weapons such as Bo, Nunchucka and Sai but we also incorporate knife fighting and edged weapon defence.

Kid's Classes. NUCA welcomes children into our classes. We teach people of all ages in an open learning environment where children train with parents or other adults.

Okinawan GoJu Ryu Kenkyukai

This is a karate organisation set up to promote research into the practical application of Okinawa Goju Ryu Karate kata and technique. It was instituted by Masaji Taira Sensei (9th dan, Hanshi), to provide a collaborative learning group of like-minded pracitioners to collectively advance our karate..

Taira Sensei heads the Okinawa Goju Ryu Kenkyukai, is best known as a researcher and practitioner of the bunkai of the Goju Ryu kata, and is renown for being unusually open in his teachings, feeling that the techniques and learning must be shared, for their preservation and to test their effectiveness. 

NUCA is an accredited Okinawan GoJu Ryu Kenkyukai Club and Grant Rohde is accedited as a Jun Shibu of the organisation.
