Hello DW90, a warm welcome to the site.
What you have asked is precisely what I didn't want as well, so I've 'opted out of my health record', so copy and paste this in your search browser as one option 'opt out my health record gov au', the other way to do this is typing 'myGov account' then select the My Health Record you want to cancel. ...
Select the 'Profile & Settings' tab.
Select 'Profile' and navigate to the end of the page, click 'Cancel My Health Record'.
You can also have myGov on your mobile which will take you through the process, and sorry all of this may seem confusing, so please let me know.
I have 'opted out of my health record', although others don't want to do this, and I accept that, but I certainly don't want my insurance company to know my details.
Good thread.
Geoff.
