‘a well person who simply needs a letter to see a specialist should be able to get one without requiring a GP consultation’

Why does a ‘well person’ need to see a medical subspecialist rather than a specialist in Primary Care – their GP?
They don’t need a letter to ‘see a specialist’. Anyone can see a subspecialist doctor in Australia by paying their own money for it. A GP referral is only needed so that the patient may receive a Medicare rebate for the subsequent subspecialist consultation.
A referral is a formal transfer or handover of care from one doctor to another. I don’t think the Qoctor AI measures up.

It’s all artificial and no intelligence.
