"Dad got us into it at a young age. She’s doing really well, I’m so happy for her," Sam Roestbakken said.
"I like to think that I was one that helped her achieve what she is achieving. She’s doing really well so it’s good that we can both get out there and play football.
"It’s a good thrill for the family, we’re all happy for her, especially me, I’m really proud to call her my sister.
"But at the same time I’m a little bit jealous that she is living that life that I want to achieve as well, but good on her."
Roestbakken is beginning to plot his path to the top flight and he is weighing up a move overseas to see if he can crack the big time.
He had his chance before but now the 20-year-old says he is ready to put all his eggs in one basket.
"I’m looking at heading overseas after this season and trying to crack it over there, and try and get a little bit more of an opportunity," Roestbakken said.
"I’m happy playing here in Canberra and I think I’m starting to establish myself here. I think I’m ready to make that move so if I can do it I’ll put all my eggs in one basket and give it another go.
"I was looking at heading back over there when I was 16 or 17 but I just wasn’t committed enough. But now that I’m older and mature I really want to give it another go again so I’ll see if I can commit to it and see if I’m at that level."
Monaro stunned Canberra Olympic to open their campaign and the 1-0 result raised plenty of eyebrows in Canberra soccer circles.
But it certainly didn't shock Roestbakken and his Panthers teammates under new coach Zoran Glavinic's regime.
"We’re feeling pretty good after that good win in the first outing of the season," Roestbakken said.
"We’re feeling pretty confident but at the same time we know that teams are going to view us as a threat this time. It’s a good situation to be in though, hopefully we can go out and perform the same as we did last week."
