The team from the nation's capital suffered a 4-1 loss at the hands of Brisbane Roar last round with the result ending their top four hopes.

Canberra was able to get back into the game but just like the first half, a defensive error led to the home side extending their lead.

"I would take responsibility for the scoreline but in terms of the way the girls played that's just not the Canberra United that I've coached all season," Garriock said.

"There were just too many players, big players, who didn't perform at their best."

It's the second consecutive season that Canberra has failed to make the finals of the W-League after finishing fifth in the 2017/18 season.

Garriock took over the head coach role in August 2017 and worked with the squad already in place for the pst season but after being in the role for a full year, she was able to build a squad, one her and the coaching staff were excited.

However, it didn't always run smoothly with international players having to leave and season-ending injuries to the newer squad members.

"Going into the season, I was really excited for the squad and I think some results didn't fall our way," Garriock said.

"We didn't close out games throughout the season. In the short season, you do need to close out games so that's one thing to reflect on."

While their season may be over, Garriock says that the groundwork is already in place for the next season. Although there is one position she needs to firm up.

"We have a solid foundation but I do need to find a striker to finish off those goals and depth as well," Garirock said.

"In terms of our culture, in terms of the players, week in week out and their attitudes are phenomenal."

Canberra United play their last home game of the season on February 5 against Melbourne Victory.
