For three of the young fighters, the wins were a first time occurrence.

"Caitlyn Usher, Olivia Usher and Grace Isaac have been training tirelessly, and to be successful in their fights was outstanding to see," Muay Thai instructor at Blue Eagle Training and Fitness, David Flood said.

"Caitlyn Usher was a true sportsman displaying control in her very first fight and Olivia Usher fought three hard rounds against a male opponent, she kept her cool and moved forward the whole fight and was victorious."

St Joseph's Catholic College student, Grace Isaac, stepped up to take on an older opponent, and despite a last minute rule change fought a structured and aggressive fight, Mr Flood said.

Winning all three rounds, the Muay Thai instructor said he was very proud of the tireless effort and sportmanship.

"Grace fought a very hard and much older opponent, showing composure, and fighting to our game plan.

"She was always on the front foot and didn't give an inch.

"She displayed accurate punches, kicks and knees to come away a very decisive win, showing everyone what she was capable of."

Isaacs had previously competed in Darwin and Perth this year, but was unsuccessful in her bouts against more experienced fighters.

With four fights now under her belt she is preparing for her next competition in NSW in August.

Seasoned fighters, Blair Andrews and Jarrod Frazier were also successful on the night.

"Frazier fought what can only be described as a clinical demonstration of what Muay Thai is all about," Mr Flood said.

"He was cool, calm and calculating, stopping his opponent in the third round and taking out the winning title by a TKO."
