OAKHILL College's futsal team are the new state champions.
Throughout the championships in Penrith on July 25, the boys conceded two just goals as keeper Max Bestford kept six clean sheets in seven games.
In the grand final they faced Georges River College Oatley Senior Campus and won 1-0, with the goal being scored during the first half by Edward Rinaldi.
Of the 35 state teams that competed, Oakhill made it to the grand final undefeated, beating every team, including reigning champions Bossley Park High, in the semi-final.
Coach Mitchell MacLaren said he was proud of the boys.
"They played with heart until the end and they are already looking forward to the challenge of defending the title next year," MacLaren said.
"They went throughout the 13 games undefeated, an amazing effort considering that half the boys hadn't played Futsal at a competition level before."
Player Edward Rinaldi, 16, said they won thanks because of the team's camaraderie on and off the field.
"We supported each other throughout," he said.
Oakhill had won the regional championships at Dural Sport and Leisure Centre in June.
The team won the tournament undefeated, beating Glenwood High School in the grand final 5-2.
Captain Brad Mitchell scored a hat-trick in the opening five minutes.
Futsal is a five-a-side indoor version of soccer. It is played on a basketball- size court that requires fast play and precision.
NSW is the only state to hold a competition, so there are no national championships.
