His father and three uncles are in the noble profession.

So that's why graduating from the Fire and Rescue NSW Emergency Services Academy was "the best experience of my life".

Mr Jones, 24, was one of 16 new recruits to complete the training and graduate last month.

He encourages everyone to apply in the latest round of recruitment, which closes on Sunday.

"Everyone from all cultural backgrounds and different professions should apply to become a firefighter," Mr Jones said.

"We help diverse communities so it is good to have people who speak different languages and have different religions and trades."

Mr Jones said he always knew he wanted to help people so he continued to apply for the academy even though he was rejected twice.

"I knew I wanted to become a fireman from a young age," Mr Jones said.

"My father is a fireman and he suggested I get some life experience before I apply to be a firefighter. So I went and became a carpenter.

"I enjoyed helping people create their dream homes but I wanted to do more for the community.

"I followed in my father's footsteps and became a fireman.

"The application process is no easy feet so I had to work hard and I knew I would eventually get in."

Mr Jones said the academy provided "world-class training" where he learnt to do urban search and rescues, how to extract someone after a car accident and received basic life support qualifications.

"The main focuses from the training were to protect the irreplaceable and prepare for anything," he said.

"We did theory in the morning and then we put what we learnt into practice through our training in the afternoon."

Mr Jones said he was looking forward to getting to know the other firefighters at his new station, Marrickville.

Fire and Rescue NSW Commissioner Paul Baxter said the recruitment campaign, which normally attracted over 6000 applications each year, was targeting applicants who reflect the professionalism, dedication and values of the service.

"Our newest class of graduates - which include a former interior designer, professional lifeguard, physiotherapist, commercial diver, youth worker and builder - demonstrates that great firefighters come from all types of backgrounds," he said.

"I hope their success inspires others to apply for a diverse, challenging and rewarding career as a firefighter."

Commissioner Baxter said applicants would need to complete an online application and undergo a series of tests, including problem solving and a Physical Aptitude Test.

"Successful applicants will be trained to be prepared for anything, as our firefighters do so much more than fight fires," he said.

"We are looking for fit, passionate and resilient individuals with well-developed interpersonal skills and the capacity to undertake the many different roles of a modern firefighter, including fire response and investigation, community engagement, rescue and hazardous materials response."
