The Strikers will host second-placed Garden Suburb at Dora Creek Oval in the grand-final qualifier this Sunday at 3pm.

Morisset completed the historic home-and-away season with a 3-nil forfeit victory over Charlestown (who could not field a team on Saturday), then a 3-nil win over Newcastle Suns at Connelly Park on Sunday.

The Strikers were scheduled to play another catch-up game earlier this week, against Westlakes, but competition organisers deemed the match unnecessary, and recorded the game as a nil-all draw.

"For the first grade to win every game they played this season is a fantastic effort, and I don't think that it's been done in this competition," Morisset spokesperson Michael Gavin said.

"The boys were ecstatic."

Key marksman Karl Gavin is in some doubt this Sunday after re-injuring his ankle at the weekend.

"Karl is under a bit of a cloud, and only played half a game against Newcastle Suns," Gavin said.
