What is a public health officer?

Public health officers work to improve and protect the wellbeing of people in the community. During Covid-19, we all saw a lot more of them in action. Led by Chief Health Officers across the country, the sector aimed to act in the best interests of the Australian public, and worked to better understand the potential threat while keeping us up to date with the latest facts and figures. 

But there are many other ways public health officers can have an impact. As community wellbeing advocates, they’re involved in all sorts of projects. For example, some create programs that teach drug and alcohol safety in schools, while others write better policy for more balanced nutrition in aged care.
