The former Central Coast Mariners player unleashed an unstoppable rocket to ensure his Scottish Premier League side beat Killie 1-0 by the skin of their teeth at Rugby Park.
But Rogic admits his sensational strike was no fluke and he had been scoring similar strikes for fun at the Hoops Lennoxtown training centre.
"I felt last week in particular I had a really good week," Rogic said.
"And when you get a chance you just have to take it. It doesn't always happen like that but fortunately this time it did. The last couple of days in training I did score a couple but not quite like that.”
Rogic had been sidelined with an ankle injury he suffered at the start of the year but has made an encouraging return to full-fitness.
"At the end of January, I hurt my ankle against Hamilton so I was out for a few weeks, and when you lose your place in the team sometimes, you just have to work hard, we've got a good squad, and show the coaches what you can do in training,” Rogic said.
"As a substitute you want to try and have an influence on the match. Obviously we all want to be starting, but that's a decision the coaches make and, as a player, you just have to respect that and be as ready as you can as a substitute and try to have an influence when you come on. Thankfully that was the case for me."
Twenty-four hours after the game and the 23 year-old on his way back to Australia boasting a huge grinning smile as he met up with coach Ange Postecoglou and his international team-mates.
