The ACT is fast becoming the futsal capital of Australia - having already produced Tom Rogic - with both the men's and women's open teams vying to be crowned national champions.

Both sides fought their way through the five-day tournament to play in Friday's Futsal National Championship grand finals at the Australian Institute of Sport.

The ACT men needed a win in their last group stage match to avoid a surprise elimination, but three goals in the first eight minutes set them up to obliterate South Australia 6-0 and book their place in the semi-final.

It was a second-half hat-trick from Robbie Cattanach in the semi-final against NSW Metro which allowed the ACT to run away with a 4-1 win and earn a spot in the grand final against Victoria, which defeated Queensland in the other decider.

Cattanach, who had an outstanding season with Cooma in the ACT Premier League, is sharing the scoring lead in the tournament with six goals.

In the four-team open women's competition, ACT entered a reduced squad of nine players for the five-a-side game, but showed it has the talent and fitness to run out games, finishing top of the table to claim its place in the grand final. The home side conceded just five goals in six games and cruised through the final-round match with a 4-0 win over NSW Regional.

Rachel Crittenden scored one goal in the win to leave her two goals clear at the top of the scoring table with six.

The ACT will also meet Victoria in the grand final, the only side to have beaten the Vics during the tournament with a 2-1 victory on Wednesday.
