The 21-year old Australian has been with Killie all season after initially arriving at Rugby Park in the summer and has made 25 appearances in all competitions for the East Ayrshire outfit.
Despite Kilmarnock battling it out to avoid finishing second bottom on the table, which would stave off a relegation playoff, Irvine insists he has thoroughly enjoyed his time with the club.
"It's been a good experience, it's really helped me grow as a player. Playing in 25 games or so is definitely more than I was going to get at Celtic,” he told the Daily Record.
"We're in a bit of a dogfight for that second bottom play-off position, so the pressure's even higher."
As for his imminent return to Celtic, Irvine was hoping to force his way into Neil Lennon’s starting line-up next season.
"I'd find it hard to sit in the reserves after the season I've had,” he added.
