Agree JoWA that there was plenty of opportunity for familiarity between BRE & CG.
On the night CG went missing - she was having drinks with colleagues from the law firm Blake Dawson Waldron, where she worked before going overseas.
CG also studied law with someone who was in the same year as BRE's at school - see below from article:
"Mr Edwards’ old high school friends were equally surprised, saying that one of their year 12 students had studied law at the University of Western Australia with Ciara Glennon".

EE was a a legal secretary at Corrs Chambers Westgarth - I have read that someone from BRE's year at school worked with EE.
Plenty of opportunity for connections - this point is discussed in detail around the below pages in WS:
