The Probationary Constable was among more than 300 to graduate last week, making Class 365 the largest group of graduates in more than 10 years.
Pro Const McDonell is keen to be a part of the community, which he said is not too dissimilar to where he grew up.
The 20 year-old was born and raised in Wagga.
At the Goulburn NSW Police Academy, Pro Const McDonell said his training took eight months in total, including four months on-screen learning the checks and protocols.
The second half consisted of practical and physical training.
As for why he wanted to become a police officer, Pro Const McDonell said the job ran in the family.
He had also seen the impact of the job first hand, inspiring him to enter the police force.
“My mother was a police officer,” he said.
“I heard stories about her time and experiences, and I want to follow in her footsteps.”
“I also just want to make it (the community) a safer place.”
Pro Const McDonell has already adapted well to Deniliquin, and said he related to the atmosphere.
“I lived on a farm all of my life, and I’ve always loved the country.
“I didn’t choose Deni, but I’m very happy to be put in Deni.
“I’ve been here only a few days, but Deni feels like home - just a bit smaller.
“It has all gone smoothly so far.”
Outside of work, Pro Const McDonell’s interests are well suited to Deni while he also suggested he might have to take up a new hobby while he is here.
“I mostly like to go to the gym, camping and motorbiking.
“I think Deni is a pretty good place for those things.
“I might have to get into fishing as well.”
