Canberra winger Cotric is the latest in a long line of players whose eligibility is blurred but according to the man himself, there's no doubting where his allegiances lie.
"I grew up in Canberra, I grew up there my whole life," Cotric said.
"I was automatically NSW. I love NSW, ever since I was a kid. A few of my family and friends are from Queensland but I always hated them."
He was born and raised in Canberra's southern suburbs and played his junior football with the Valley Dragons.
He was scouted by the Raiders from a young age, playing Harold Matthews Cup and SG Ball with the green machine before getting his first taste of representative football with the ACT Schoolboys team.
Then at 15, he was selected in the NSW Under-16s before playing under current Blues coach Brad Fittler in the Blues' under-18s.
While his selection for the Blues will raise eyebrows in the sunshine state, under NRL rules, players born in Canberra are NSW eligible because the NSW Country Rugby League oversees and controls the game in the ACT.
Cotric's said his Origin debut represented the realisation of boyhood dream having grown up idolising the likes of Jarryd Hayne.
"There was one tear shed when I was with my dad, he gave me that hug. Just to see him that proud, I shed a tear," Cotric said.
"I watched it as a kid and with my mates, we'd all get together and have a big BBQ. Jarryd Hayne at the likes of them boys, I can't believe it. I've always dreamed of it."
Cotric will make his Origin debut at Suncorp Stadium next Wednesday after Tom Trbojevic's hamstring injury opened up a spot on the right wing.
Since earning his first-grade debut with Canberra in 2017, he has played on the left flank - except for the Raiders' past two matches against South Sydney and North Queensland during which he has shifted to the right.
"All throughout the 20s I was a right side player, I feel comfortable," Cotric said.
"When I started playing grade I went over the left side. I don't mind, I like both."
