I know it seems JH testimony wasn’t particularly helpful, but it is!
If JH testimony is reliable, it seriously brings into question whether someone was impersonating MB.
For example… a woman with tan skin, brown eyes, who she possible saw years later, around 60s at a ‘return to work’ TAFE course.
If this was Marion, then it suggests she made a new ID for herself but stayed in the area where people recognised her. This new ID would not have been a formal change of name from Marion or Florabella as there are no records of that. But a new ID to ‘return to work’ would suggest a bank account, driver’s licence and insurance, and a superannuation account. How can a regular person like Marion, who has no history of dodging rules or authorities, obtain those things in a devious and unofficial way? If she did it to ‘start a new life away from her family’ then why chose to live so nearby? Why didn’t she end up in Bali or Europe as some people said she intended to?
So, if this is not Marion, then someone that lived in the area was impersonating her that happened to ‘return to work’ on her own name.
Note that Centrelink sometimes requires you to undertake courses for you to keep receiving benefits for which you need a proper ID and bank account.
