Jarrod Buick, Joseph D'Souza-Bullman and Adam Rusgnach represented NSW at the national titles last year and are joined this year by clubmate Tim Hawken.

The Coniston club dominated the men's gymnastics Level 8 open division at the state titles, with Buick backing up from his fourth-place finish in the Level 7 open division in 2014 by winning the Level 8 state crown this year.

The 14-year-old pipped SCGA clubmates D'Souza-Bullman and Rusgnach, who finished second and third respectively.

The trio are joined at the nationals in Melbourne on May 17-24 by Hawken, who will represent NSW in the Level 7 open division team.

South Coast Gymnastics Academy owner and long-time club coach Liz Medway was rapt by the performance of her four members at the state titles.

"They deserve all the success, they train very hard all year round," she said.

At last year's nationals, D'Souza-Bullman won four gold medals and was Level 7 men's open Australian champion for 2014.

D'Souza-Bullman claimed gold in the rings, vault, high bar and parallel bars and a bronze medal for the floor event.

He won another gold medal for being one of the four South Coast Gymnastics Academy members in the NSW team, which claimed the overall team national title.

Rusgnach finished second overall, after winning a silver on the rings and bronze on pommel horse as well as top 10 placings for floor and high bar.

Buick also impressed with a gold medal for his floor performance, silver for parallel bars and ninth-place standing overall.

"They train six days a week... I'm hopeful the guys can do just as well in Level 8," Medway said.
