ok. I do not think that document he showed is legitimate. I don’t think it is called the Department of Health. I think it should correctly labelled as the Department of Health and Aged Care.
Like you I cannot find any match to the text of that item he showed on video.
I did find this: https://newsroom.unsw.edu.au/news/health/cloth-masks-%E2%80%93-dangerous-your-health
but it is not from the Fed Health Dept.
