Travelling more than 3.2 million kilometres a year, the Court Escort Security Unit (CESU) is responsible for transporting more than 175,000 inmates across New South Wales.
Senior correctional officer Burns (full name not used for security reasons) said it was a unique profession that often went unrecognised.
"It's very much an out-of-sight, out-of-mind operation," he said.
"Behind the closed doors or walls of the jail, the greater community don't realise what goes on."
Corrective Services NSW is now shedding a light on what's involved in this important part of the system.
About 10,000 people work for Corrective Services, with a team of around 565 staff who transport inmates from prisons, courts, police stations and medical facilities.
It's an around-the-clock operation that can be complex at times.
A dangerous job
Jaideep and his wife Sugam (who asked that the ABC not use their full names) moved from Sydney to the regional town of Albury last year.
The husband-and-wife duo have been working for Corrections for the past two years and said no two days were the same on the job.
"You're going to face the things society doesn't want to face, so be prepared for that. They prepare us mentally," Jaideep said.
They said the biggest challenge in the role was managing intoxicated inmates, those with mental health issues and the potential for escapees.
"We have to keep a close eye on them so we don't lose them or they don't get hurt," Jaideep said.
"But that's when our training kicks in and we use all the techniques we learnt from the academy.
"Our job is to keep our community safe. Our job is not to judge them."
Mr Burns said each staff member was well trained to be able to manage the most difficult of situations.
"The goal is for my staff to go home in the same condition they came to work, so it's a matter of training," he said.
After completing a 12-week course, all staff are required to do more training in dealing with volatile inmates and mental health.
Sugam said it was also beneficial working alongside her partner, because they were able to debrief each day and work out the best strategies to handle certain situations.
"We work as a team, so if something comes up we help each other," she said.
Jaideep said through training they had learnt many techniques for managing volatile situations, but the most important was being able to talk with inmates.
"The communication is the best tool that makes them calm down," he said.
"That's our duty of care to look after them ... we make sure they know they'll be fine in our custody," Sugam added.
