The NSW Police Force has welcomed 349 new probationary constables, as Class 368 attests, becoming the largest class to graduate in 13 years.

Graduating students began their first day as sworn officers on Monday, the same day nine cadets started their police cadetship program – the first since 1977.

The cadets – all aged 17 and 18 – have spent the last four weeks undergoing an induction.

For the next 12 months, the cadets will be placed at The Hills and Sutherland Shire Police Area Commands, where they will undergo paid experience, learning firsthand what life as a police officer involves.

Six police dogs were also attested - three drug detection dogs named Horrace, Bachar and Quattro, and three general purpose dogs named Evie, Charger and Pride.

Class 368 is the last class to be graduating with Charles Sturt University, before the program begins with Western Sydney University.

In recognition of the long-standing relationship between the NSW Police Force and Charles Sturt University, a lecture hall at the NSW Police Force Academy has been renamed after the university.

Minister for Police and Counter-terrorism, Yasmin Catley thanked every recruit for their commitment.

“To every officer who attested, and every family standing behind them: thank you,” Minister Catley said.

"NSW backs you, NSW is grateful, and we wish you a long, safe and rewarding career.

“Every one of these 350 officers represents more support for the frontline and more protection for communities right across the state – and each of them have chosen duty, service and the responsibility of keeping NSW safe.

“The Minns Government is proud to be rebuilding the NSW Police Force.

"For too long, the former government failed to invest properly in our police.

"They capped wages, let recruitment slide and left the Force under pressure – and we know thousands of experienced officers left because it.

“There is more to do, but the momentum is real – the last class broke a 13-year record, and this class has broken it again.”

Commissioner Lanyon said he is incredibly proud to welcome Class 368 to the force.

“It is my privilege today to welcome part of a new generation of officers who will shape the future of the NSW Police Force,” Commissioner Lanyon said.

“Each recruit has already shown discipline, courage and commitment to becoming a police officer and I’m confident in their ability to serve the communities they have been placed in.

“I am proud to welcome the recruits to a career that will demand a lot of them but one that will make an impact.”

The Commissioner will also present a retired Senior Constable with the Commissioner’s Valour Award for his bravery during the pursuit and arrest of heavily armed offenders at Tugun in February 2015.
