Local twins Adam and Luke Moffitt will be among the corrections staff who will be celebrated on Friday.

Adam decided to join Corrective Services NSW 11 years ago, his older brother by five minutes, Luke, joined soon after.

While their CSNSW careers have closely mirrored each other's, they aren't identical so they can't play tricks on their workmates, and they say they don't feel each other's pain.

The 2020 National Corrections Day theme is We Are Family, focussing on the camaraderie of CSNSW staff who work together like one big family. Many of our staff, such as the Moffitt family, are also related.

Adam says it's good working alongside his twin brother at the Mid North Coast Correctional Centre..

"We've worked with each other on and off all our lives, and we can talk to each other if there's been a hairy situation," he says.

Adam and a group of inmates are working to rebuild the habitat of one of the state's biggest koala populations after it was devastated by last year's bushfires around Port Macquarie.

Adam is well qualified to take on the bush regeneration project having worked in horticulture.

The 41-year-old began his CSNSW career as a custodial officer at several prisons before taking on the overseer job and enjoys doing both roles.

"Teaching the inmates new trades is fulfilling, and it's a positive thing for the prison and the community," Adam says.

"There are so many diverse jobs in CSNSW and plenty of opportunities, such as the K9 unit, transport and executive roles."

Luke began his working life as a carpenter and after working at various prisons he now works in the Immediate Action Team, which responds to security and emergency situations at the prison.

Despite often being faced with volatile situations, he likes the team environment.

"We have each other's backs and there needs to be a lot of trust in this job," Luke says.

"We have good mentors too and you learn something from them every day."

CSNSW includes about 5,600 custodial officers, 1,100 Community Corrections officers, 650 industries workers, 700 psychologists and programs officers and 680 administration people.
