Coached and mentored by Grant Cunningham, Tyler and Josh Desborough, Sam Swain, and Troy Hill travelled to Sydney twice last month for two separate bouts.

Hill made the most of a City verse Country amateur boxing night in Punchbowl on March 9, achieving his first win in the ring and the opportunity to represent on a state level.

In a three-round, two-minute bout, Hill gave his everything in style to defeat Tamworth's Cameron Bright.

"He did everything we asked and he delivered. He fought the best fight of his life; very technical. It was his first win out of eight fights," Cunningham said.

Hill earned the right to represent team NSW at a State of Origin boxing night at Toowoomba in July. Winners of each match will be honoured with the opportunity to fight for Australia against New Zealand.

On March 30 Swain ended ex-NRL bad boy Tim Simona's professional boxing career before it even started at Condell Park.

"He knocked him out in the first round but the ref did a standing eight count. He knocked him down again in the third round and won convincingly; it was a unanimous decision."

Swain will return to the ring in May where he hopes to "get a bit of revenge" against a component who previously defeated Hill.

Invincible Fitness, a charity raising funds for Westmead Children's Hospital supported by Inverell Boxing Gym, held a fundraising stand at Condell Park.

"It went well, and I'm still selling their shirts for anyone interested. We're raising money to assist young kids like Everlyn Kyling-Melohn who is the youngest child in Australia to have Lhermitte-Duclos disease, a very rare brain tumor."

The not-for-profit gym, run out of Cunningham's backyard also has a GoFundMe page to raise money for new cardio equipment for the junior mentoring program run three days a week.

The amateur fighters train around 10 juniors to give back to the future of boxing and for some extra responsibility- at no charge.

Cunningham's wife, Maryanne will help with corner work during the NSW fight, as only of very few ladies in the state to be qualified in amateur boxing.

The boys will fight on May 31 for a fundraising night to assist the NSW side, all boys will compete in support of Hill.

Later, four, young Aboriginal boys, under the wing of Cunningham, will head to a Koori boxing competition during NAIDOC Week in July.
