The 20-year-old has joined on a six-month loan from Celtic with the aim of securing first-team football.
The versatile Australian - who can play in defence or midfield - has told new boss Allan Johnston he is ready to be pitched straight into the SPFL Premiership game against St Mirren this afternoon.
Irvine said: "It's a great opportunity for me to hopefully get a regular start in a first team.
"Hopefully I can build on the experience and take it back with me and further my career. It will enable me to progress.
"You can learn a lot in youth games and things like that but once you get to a certain point, I think you need to test yourself physically against men every week.
"The thing I'm most looking forward to is pushing myself and seeing how far I can take it at this level."
Irvine temporarily signed off at Celtic in style with an appearance against Liverpool in last week's friendly in Dublin.
He said: "It was phenomenal and it was quite a surprise as well. To line up in midfield against the likes of [Steven] Gerrard was fantastic."
Irvine is now optimistic that both he and Kilmarnock can enjoy success in the coming months.
He said: "I've been really impressed so far. They've got some fantastic footballers and I really like the style of play the manager has got them playing."
