New South Wales paramedics have been verbally and physically assaulted "at least" 60 times this year, with long-term paramedics revealing the threat of violence is now just part of the job.

The figures, provided by the New South Wales Ambulance service, come as new safety guidelines are set to be introduced to help protect paramedics during their shifts.

NSW Health Services Union boss Gerard Hayes said violence from patients and surrounding public had become the norm for paramedics.

He said the assault figures provided by the NSW Government were "grossly under-reported".

"Paramedics are very concerned about going out on a job, how they're going to be treated on the job, and that actually they can get home safely," he said.

"If we were to get each paramedic to report an incident, those figures would double if not triple."

A spokesperson for NSW Ambulances said all attacks were required to be reported to the police, but new safety guidelines, to be released later this week by Commissioner Dominic Morgan, were expected to address under-reporting attacks and "near misses".

Mr Hayes said he wanted the guidelines to ensure paramedics were sent out in teams of at least two during night shifts.

"Paramedics numbers have not kept up with the growth, particularly in New South Wales," he said.

"We want to see at least 1300 more paramedics.

"We're not saying that we can eradicate problem through having two people on a case [but] it's another step in minimising the issue."

Paramedic Jason Kirkaldy - who is also a union delegate - said even after eight years on the job he felt afraid almost every shift.

"We hide it really well, we're kind of trained to," he said.

"But (we're) probably a little bit fearful.

Mr Kirkaldy said the violence was on the rise.

"Drugs and alcohol definitely play a big role in that," he said.

"At least once a fortnight minimum we're at least verbally abused on the job

"All we want to do is to help people. I have a little six month old at home that I definitely want to go home to every single day."
