The Industry Research and Development (Promote Mental Health for Small Business Operators Program) Instrument 2019 is a Commonwealth legislative instrument made under section 33 of the Industry Research and Development Act 1986. Its core legal job is to prescribe a program called the Promote Mental Health for Small Business Operators Program.
That matters because the instrument gives the program its formal legal footing. It is not written as a day to day operating manual for small businesses, and it is not a general code of conduct about mental health in every workplace. Instead, it establishes the program at a legislative level and states the program's purpose.
If you are a business owner reading this page, the practical takeaway is that this instrument is about the Commonwealth's authority to run and support a particular program. It is not, by itself, a document that tells your business to adopt a policy, submit a return, or comply with a new penalty-backed obligation.
