Six months into the state government's reinstatement of the school health nurse program, the 10 new staff around the state are regarded as helping to fill a more immediate gap, when once it may have taken a student days to get a referral and then visit an outside professional.

The school nurses were funded in the 2014-15 budget to the tune of $4.42 million over four years, with a total of 20 full-time equivalents to be employed around the state by July 2017.

Thirty-eight high and primary schools have nurses, with a further 34 set to receive them.

Ms Mackay spends two days a week at Brooks and also visits Prospect and Scottsdale high schools.

While each school has their own needs, she generally works either in the classroom or offers a one-on-one drop-in clinic at lunch or after school.

The former alcohol and drug service and youth health worker said her work takes on a few different aspects, from health promotion, good nutrition, relationships, cyber-safety and mental health.

Ms Mackay said building trust with students was a key element in her role.

"They come to me with the A to Z of health needs, some of the younger ones have come to talk to me about sleep, they're not sleeping well and the other thing you find is that they are concerned about things, sometimes it's around 'sleep-hygiene', where you find they have to put away their devices and introduce good habits around sleeping and hygiene as well," she said.

"Or sometimes they just want to come in and have a chat and get something off their mind."

Brooks acting principal James Price said the role of the health nurse was not first-aid but much more big picture, helping students with their broader, long term health and welfare needs.

Mr Price said the program allowed staff to react much faster to addressing the needs of students and the nurses were flexible enough to visit a school on short notice, if a student had a particular need.

Education Minister Jeremy Rockliff said nurses like Ms Mackay were making a difference for Tasmania's school children and creating an environment that promotes lifelong health and wellbeing.
