I use a redacted exemption which has been accepted twice when entering court. It’s nobody’s business what my condition/reaction is.
s16b Privacy Act protects us in that we are not obliged to provide personal sensitive information to anyone not providing a health service. This is my basis for redacting my exemption.
S109 Constitution supports this as the overruling legislation over state legislation.
Then there’s the PHO stuff in the Biosecurity Act that Kam mentioned.
I would be interested to know what health service the officer was providing you and if (s)he has a licence to practice.
If you do get to court, I hope you have a fun crucifying them.
