The Seahawks, last year's AFL Canberra grade three premiers, beat the Diggers, last year's SCAFL runner up, by more than 80 points in a lopsided match.

Before the trial, the women's team had its first intraclub match of the season, and got great participation numbers.

Head coach Mick Kenny said he was pleased with what he saw from new players.

"We lost a lot of experience since last year, so it was a really good opportunity for the young guys to cement a spot in round one," he said.

"A couple of the new guys really surprised me. Leigh Baghurst kicked three goals, and another bloke we got in from the Broulee Soccer Club was really good, but the young blokes impressed me most.

"Christian Filmer and Rex Lee played a bit of reserve-grade footy last year, but they've come along in leaps and bounds.

"It's going to be a big year for the like of Will Aiken and Kyle O'Malley as well. They played the bulk of the trial in the middle, and they'll have that opportunity throughout the season."

Kenny said he was happy with the team's focus on getting its structures right.

"It's a first hit-out, so our skills and work rate were probably down a bit in patches, but other than that, it was a pretty good start to the year," he said.

"Everyone's concentrating on our zones and structures, so once we get the run in the legs, we'll be better for it."

The Seahawks were missing six or seven first-team players on the weekend, but they'll get a chance to play in their next trial match against Bomaderry.

"It'll be similar to this week, we'll probably be missing another six or seven senior guys," Kenny said. "It'll be a fairly different group to what played on the weekend."
