"It's obviously a big aim from being a first-year rookie, but you've got to set hard goals," Mullett told kangaroos.com.au after stepping off the training track on Tuesday.
"I'll definitely set goals to play AFL football next year. I'll hope to play consistent footy in the VFL and hopefully push the selectors to see that I'm good enough to play at that level."
The 18 year-old was selected with North’s second-pick in the rookie draft and says it was one of the most exciting moments of his life.
"It was amazing. I had my brother, my girlfriend and my family there watching on the computer," Mullett added.
"The Kangaroos took me and I was just over the moon, I've never been that happy."
An apprentice landscaper, Mullett has had to adapt quickly to life as an AFL footballer and the heavy demands of his new career.
"It's ridiculous. We trained only two days a week at TAC Cup for an hour or an hour and a half. Just the difference in drills and the intensity is phenomenal, I can't even describe how much of a step up it is. It's been an eye-opener.
"Being a draftee you're only doing about 60% of the running, but the intensity of training has absolutely blown me away.”
And travelling from Moooroolbark in Melbourne's outer-eastern suburbs for training every day offers another challenge.
"It's killing me. I don't want to be late so I'm allowing an hour and half or two hours. It's a long way home after a big day so some days I've just been having dinner and going straight to sleep."
Hurdles aside, Mullett has already impressed with his skills at training, most predominantly on his favoured left-foot.
But it's another asset he's most proud of; standing at just 184cm he earned a reputation during his junior career as a high-flyer.
"I took a few big speckies last year so I don't mind going for a ride...for my height it's good to have,"
Mullett spent much of his time at the Eastern Ranges as a wingman and admits there are areas of his game to fine-tune.
"I want to improve my gut running and ability to run both ways and I need to be able to play four consistent quarters of football," he said.
"Last year I was in and out. I'd have a good seven minutes, then go missing for seven minutes. In those quieter times, I've just got to work into the game, put some more blocks on and put some tackles on, just so I can keep in the game for four quarters.”
