Australian off-spinner Nathan Lyon was the captain of the ACT under-19s the last time they got this close to a historic national championship.

The current crop can go one step better than the star-studded squad of 2007 when it takes on South Australia in its final-round match in Hobart on Wednesday.

Victory over the Redbacks in the two-day game and a NSW loss to Queensland in the corresponding fixture will deliver the ACT its first under-19s title.

The ACT was in the same position six years ago only to fall to NSW in the final game.

Lyon led a quality line-up featuring seven players who have gone on to secure first-class contracts, including West Australian fast bowler Jason Behrendorff and NSW opening batsman Ryan Carters.

The ACT has beaten Tasmania and Northern Territory in its two-day games to go with losses to Queensland and NSW in one-day matches.

Cricket ACT high performance manager Andrew Dawson said it would be a massive achievement for the side to bring home its first national title.

''It's been pleasing how the boys have performed considering we're taking on the development of good, young regional cricketers who missed out through the major pathway system in NSW,'' he said. ''Those lads and the Canberra-based players have clicked nicely together.

''What we felt was the boys were more of a two-day team with their style of play and it's coming along well.''

ACT has been largely without leading opening batsman Matthew Condon, who suffered a broken finger in the first game of the tournament.

The ACT Comets representative and last season's leading run-scorer in the Cricket ACT first-grade competition faces six weeks on the sideline.

It rules him out of contention for the Twenty20 game against the Sydney Thunder at ANZ Stadium on December 19.
