Well, I said I wouldn't :fence: but, having read the entire thread from the start, finally have taken the leap. Great to see so many concerned with justice for Allison and the welfare of her children. As someone who grew up in the area and being same age (but no longer resident of Qld), Allison's murder has hit home very hard.
Now, many threads ago there was discussion as to how closely affiliated the family really are with scouting. Available through Google+ (on public view) is the following interesting account and pictures.

Note the era appropriate (!) pic of Nigel, gun and children... further on you'll see lots of the family, including GBC and siblings. Interesting to see both younger siblings obviously in military garb; GBC has an earlier what looks like army or army cadets photo but that's it. Lots of copies of diaries and pics of Baden-Powell - keeping up the family ties methinks.
Further to the boat theory mentioned earlier: That particular creek opens up to the Brisbane River about another 50m maximum to the right of where Allison was found. The Mt Crosby Road runs up and along the top of some fairly high hills and there is no boat ramp/access in the immediate area unless you cross into Karana Downs and launch from the other side. Having spent a childhood going up and down this road on the school bus, I've had lots of experience with the hills! You can, however, see cars coming for some distance due to the angling of lights at night...
Further to the business partner theory: Weren't both of his parents also involved in the business? They both left at the same time... is it too far fetched to consider that the female business partner could also be his mother? Food for thought and let's be honest; who is the person who enables their little Emperors in the family first? Mum. The proximity in location to his parents, the quite strange snogging display initiated by his mother... protect and enable the golden child at all costs?
Cheers!
