The Brisbane Roar defender has been labeled one of the top defenders in the league this season and there has been excitement growing around a possible Matildas call up off the back of her consistent performances.

McCormick has not only put it her good personal season down to just being able to focus on a single sport but also just having fun.

"Just trying to focus on me and my mentality all year has been about enjoying yourself, have fun and don't live with any regrets," she said.

"I think it's helped take the pressure off and it's contributed to the good personal season I've had.

"If anything comes out of it then that's fantastic for me and I'll be taking it with open arms. Any opportunity to represent my country comes first over anything but at the moment I'm focused on contributing to the team."

In what was originally meant to be a half-season contract so she could go back to Adelaide for AFLW pre-season with the Crows, turned into a season-long adventure.

There was one compromise though, that the 24-year-old would play in the Crows season opener, which meant she would miss the Roar's last regular season match.

Previously, McCormick had to juggle both football and Aussie Rules when their seasons overlapped which at times had been difficult.

"It's quite difficult to sort of know where I am but it's been good for me and the mental side of things," McCormick said.

"Last year, it felt like day-to-day I was switching codes and getting a little bit jumbled in the head and maybe that affected my performance."

After falling at the semifinal hurdle last season, Roar are ready and raring to go against long-time rivals Sydney FC.

It's one of the OG rivalries in the league, having previously faced each other three semi-finals and two grand finals. The two previous times these sides have met this season have seen Sydney take the points in a 3-1 and 5-1 win so the stage is set for a monumental game at Dolphins Stadium.

"Finals football is a new ball game and we will be excited and raring to go," McCormick said.

"It great to have a home semi. It's fantastic for us to have our family in the crowd. We had a great game here last time and we will be taking that into this game. We're excited to be back here."
