Hi! Wagga Wagga was mentioned in episode one, about 8 mins in. Says that she studies at the now defunct Wagga Wagga college.
In 2013, an article ran where it stated that she studied in Armidale:
Searching for clues to find missing mum
She may well have studied at both- but my question was deleted so I don't know. If she did study in Armidale, then that may point to a reason why she may have ended up back in the town, potentially meeting with foul play. The most that I can find about the search following the crimestoppers tip is that it was near une- which is not where the teachers college was- it was in town, with the university on the outskirts. A lot of training teachers lived in une accommodation at Smith House, but not all- some ended up boarding privately, or renting their own accommodation. Many had part time jobs- if we knew where she studied, it might be another area to sleuth.
I cant find a site for the Armidale grad ceremony programmes, but I have sent an email to the archivist to find out where they are- possibly in the archives at the une library, in which case I will have a look and take pics to share. I don't know when she graduated- on the Wagga site I looked at 15 years of programmes, to try and cover the times.
