I don't know Australian law but in some parts of the world this sounds like a sweet future settlement. Lawyer up ASAP - before Monday, before they do anything. Seek support from a local professional to know how exactly to handle this situation in your favor.

To answer the question: I wouldn't ever do it. I have ADHD, there is nothing embarrassing in my med records but I would not trust any unrelated company (employer, client) to handle and erase this data safely. It's private and absolutely not intended for them.

If I may ask, what happened prior to the request of your employer? Did they found otherwise illicit drugs on you and require this documentation as a proof that you are allowed to possess it?

You must be American. One of the few places where a “sweet future settlement” is the most common outcome.

For many other places it’s fines for the employer, potential back pay and a settlement of a few tens of thousands (severance).

Yeah, it's pretty great being American.
