Both me and my girlfriend were majors of our promotions and had more than enough in the way of academic achievement to become doctors, but the insane workload was a very effective deterrent.
Or if we must have them, please keep the confined to the minute clinics at the drug store and bar them from billing themselves as real GPs.
I'm in Tasmania, so here's the a PDF from the Tasmanian Department of Health Services explaining what a Nurse Practitioner can do, including prescribing some medication and interpreting diagnostic test

A friend of mine was an ICU nurse in Canada before moving to Australia. It was a long and painful process to get qualified again, and when she did, she found out she had been demoted from being able to meaningfully improve patient care (eg the prescriptions and diagnoses you mention) to a robot carrying out orders.
Making positive contributions to society doesn't change the fact that you're being exploited. It's become increasingly clear that Doctors (at least where I'm from) have low pay early in their careers, unsafe working conditions, and have almost no life outside of work. On top of that they have a stressful job involving interacting with members of the public.
