Ok ... I have been watching this forum for what seems like forever... Just lurking and watching
I can't give you guys any recent information but...
I knew GBC and his family in my childhood and early teens
I can personally confirm
yes GBC did spend time in his child hood in Toowoomba
Yes his family were heavily involved in both the scouting and guiding movements in Toowoomba
I believe he went to Toowoomba Grammar School although I am not 100% sure as that was nearly 3 decades ago
As a young teenager he did speak about the Freemasons
As for what he was like back then... He was pleasant, polite and contribitive but I always found him a bit strange and distant ... Some times almost as if he spoke another language I just could not relate well with him as he presented as if he thought he was above all others, he was quite often quitely reserved and indifferent to others in a creepy kind of way...I found this the same for his sister.... His younger brother was different again more grounded and cheerful with a easier more relaxed personality
In activities that involved GBC I would often feel as if I had no place being where I was almost as if being a girl made me lesser and I felt his frustration as a bad vibe if and when I achieved or contributed anything...making him somebody I will never forget.
As for the parents they would often be involved in various events etc ... Participating and supporting but to me they were just strange ( but I will also say that I have found many white south Africans to be strange) with a demeanor of better than the rest
As for what older members of family and friends say about the BCs .... Nice enough, polite yet weird, wired differently
Ok this information may not be useful to your sleuthing but I think it may confirm some conclusions that you guys have be building about his background
As for did he do it or did he not ... Or better yet could the boy I once knew be capable of doing it and trying to get away with...my answer is just maybe...I am not prepared to judge either way having said that I suppose I am saying it is not impossible that the may have.
