"I'm very grateful he is always following me around to all my games, my mum and dad are really awesome and my partner too," she said.

"They've rarely missed one of my games," McGregor added.

This is the third year McGregor is donning the Blues jersey having made her debut in 2016, just two years after she took up the game thanks to a suggestion from NSW captain Maddie Studdon.

The Blues, who came into camp on Sunday, have been training well in the lead up to tomorrow night despite having five debutants in the side.

However, McGregor is confident with the way the team has been going as they look to take their third consecutive title.

"Mentally we have given ourselves every opportunity to be victorious again on Friday night," she said.

"I think once again we've got the team to win.

"I know Queensland will have that mindset as well, they are a strong side and they are going to be a really tough opposition but I really believe in our girls and that we can get the job done," McGregor said.
