Do I need a medical certificate clearing me for work, school, university or other settings? (NSW Health)
Frequently asked questions about COVID-19 and safety in the workplace.
No. If you do not have any symptoms there is no testing that can be done to predict whether or not you will become unwell. It is not possible to issue a ‘medical clearance certificate’.
Once 14 days have passed since you returned from overseas, you have passed the time in which you would become sick if you were exposed to COVID-19. If you are still completely well 14 days after you arrived then you will not get COVID-19 from your time overseas, and you can cease self-isolation and return to work, school and university.
