But that doesn't mean attending the World Cup as a squad member of a nation ranked sixth in the world is any less special.

“It has always been my goal to play for the Matildas and to get the call up, I wasn’t expecting it this soon," the humble Matilda said.

Roestbakken was an injury replacement for former Matildas stalwart Laura Alleway, who suffered through much of the W-League season due to injury and mixed form, eventually succumbing to a foot complaint.

"To get the call up to come to a World Cup is just an unreal feeling and it couldn’t have happened at a better time, so I am so honoured and so grateful to be standing here today," Roestbakken continued.

“I am absolutely gutted for Laura (Alleway), she is an amazing player and she does deserve to be here. (But) these things happen in football and it is unfortunate, and I wish her all the best in her recovery.

“All the girls and the staff have been excellent. Coming in and transitioning from the Young Matildas to the full women’s team, the girls have been great and really supportive, and so have the staff.”

Despite being named in Milicic's squad, Roestbakken is yet to make her Matildas debut, which could lead to a very memorable match against Brazil if Milicic decides to shake up the team following the disappointing 2-1 loss to Italy.

But while she's a novice at Matildas level, the Future Matildas breakout star has already made 10 appearances for the U20 national team.
