The 20-year old Australian midfielder joined the Hoops from Central Coast Mariners last month and although it feels good to have made it to such a club, he is aware he has plenty of improving to do to assimilate to life with the Scottish champions.
"I have progressed at a fast rate so it's been a great 12 months and hopefully I can continue to develop and go forward in my career," said Rogic, who less than a year ago was playing for Belconnen United in the ACT Premier League.
"There were probably times when I doubted what was going to happen in my football career.
"The past 12 months have been great but it certainly hasn't come without hard work. I know that.
"This is really just the beginning and I have a long way to go and a lot of things to work on before I can consider myself a good footballer.
"But I feel I am in the right hands and in the right place here at Celtic."
