So, I was looking at the Australian Chief Health Officers (CHOs), and couldn't find one for Tasmania.
Upon further investigation, it looks like the Tasmanian Health Department was re-organized in 2018:
As you will be aware, the new Tasmanian Health Service Act 2018 also comes in to effect on 1 July 2018 which means that the Tasmanian Health Service also now reports directly me as Secretary, Department of Health.
Absent from this list seems to be a CHO. Why is that? Did the Tasmanian Health Service Act 2018 make it obsolete?
