Nigel King and Chris Cooper have been invited to Okinawa Japan to compete in the Super Karate-do Okinawa World Grand Prix in August.

Shihan Nick King seventh dan Kyoshi, who is Head instructor at Inverell dojo with branches that include Glen Innes, asked for the pair to join his team.

They will take on hundreds of competitors from over 15 countries in the hotly contested event, with martial artists travelling from countries as diverse as Pakistan and Iran to Portugal and the USA.

Okinawa is the birthplace of all Karate.

The team from Glen Innes earned attention with a series of placings in a recent Brisbane competition, and in a regional comp in Tamworth.

The specific form of karate taught in Glen Innes was founded by Shihan Nick is called Jin Ryu Kan, which translates to "king dragon school". Sensei King, Glen Innes branch's instructor, actually started martial arts by learning Tae Kwon Do but when he left Darwin was forced to start again from scratch by a shortage of instructors.

"Some people when they go through new katas or new styles of martial arts they say they don't want to start all the way back at the white belt but I believe it shows respect that you want to learn from scratch," he said.

He started training with Nick in 2001, winning national titles, but due to a series of surgeries he had to stop for several years. He has been training again in Jin Ryu Kan since opening Kings Gym in 2014, opening the Glen Innes branch of karate in 2017 under Shihan Nick.

Nigel, who is 41, is proud to represent Australia on the world stage. While he has been training most his life in Martial Arts, he never imagined he could compete overseas at the highest levels.

He said he's excited for his students.

"I am a little nervous because I've never actually had any of my students go to Japan or compete at this level," he said.

"I was really quite excited when I had some of my first students go to Tamworth, Brisbane and things like that last year.

"This is on a much grander scale than that."

He said the sport is actually mostly about your mental attitude and concentration; he took it up because he wanted to improve his memory after a car accident.

"That's what a lot of the kata is, it's the application of knowledge of what you've been taught, your different blocks, your kicks, your takedowns and defense," he said.

"There seems to be a lot of different types of martial arts. All ancient societies have their own sort of structure. China has Kung Fu, so that's their style. Japan has their Karate. Korea has Tae Kwon Do, Israel has Krav Maga, Thailand has Muay Tai.

"It's basically all working with the human body so there's only a certain amount of movements that you can do, but they're all slightly different or interpreted differently.

"It is very very physical; if you do it properly by the end of your minute to a minute and a half you're out of breath. It's incredible just how full on it can be."

The competition will take place on August 10 and 11.
