A total of 168 competitors from 21 Kumiai Ryu Martial Arts System locations from across Australia attended the championships, held this year at Dubbo.

Thirty-eight members of the Dubbo dojo contested this year's nationals with events available for members as young as four years old to competitors in their 60s.

Contestants participated in a range of activities which was reflective of their age and/or experiences including kata (forms), light contact sparring, full contact sparring, sword combat, sumo wrestling, modified Muay Thai and MMA.

A real star on the day was seven-year-old Rhianna McMullen, who secured four gold and one silver, and was awarded the most spirited junior (under-12s) competitor of the day.

Fourteen-year-old Hamish Grant, who has only been training for 12 months, also excelled with two gold, two silver, two bronze and one fourth place.

Another highlight was the Dubbo demonstration team consisting of Hamish Grant, Dylan McLauchlan, Jordan Heaton, Shadia Muller, Caitlin Powyer, Bailey Jones, Wasim Radwi, Kaiesha Clarke-Russo, Joe Jacobson and Emelia Polansky, winning the highly sought-after national demonstration team champions trophy.

"All members of the Dubbo dojo participated in good spirits and did exceptionally well, considering for most of them it was their first National Martial Arts Championships," Dubbo dojo instructor Shidoin Daniel Andersen said

Several team members have been selected to represent NSW in the AMAC Australasian Championship in Melbourne on November 28 and 29.

Medals and trophies were awarded to the top-four placegetters in each event, with Dubbo students taking out 23 gold, 26 silver, 23 bronze and 19 fourth places.
