imo, the theory there is business/finance/more than one person associated with Allison's murder is unlikely.
Based on accounts of dealings with him, GBC is an egotist, who fell on his feet by joining the real estate industry during an unprecedented boom in Queensland (maybe strategically, or possibly just dumb luck). As someone pointed out, a drunk monkey could have made a fortune during the boom time. Now, the game is for real adults, and the industry is in the doldrums. Anyone who was getting by on luck and half-truths would be well and truly screwed. Rather than learn the proven footslog methods of selling real estate, Gerard has got by thinking writing a self-inflating blog and joining every committee and sub-committee in the area makes him and his business 'popular'. However, just look at the sold properties for the last couple of years, and see how many times Century 21 Westside features. (save time, it's not many at all). Unfortunately for Gerard, the local community (or at least those selling houses) weren't impressed by the ravings of a yellow-jacketed pinhead (no offence Pinhead on here ;-))
He moved to rent in Brookfield to hang where the well-heeled are. He was never really accepted - the long term Brookfield types would say 'Baden-who?' despite him thinking he had 'arrived'. He probably got himself on the School P&C for the same reasons he joined the local Chamber of Commerce - everyone look at me - I am 'the man'. The family was known in school and church community. Fortunately most of the perception of the Baden-Clay name in the local community came from people's dealings with Allison. Strange, and typical, that most of the positive impressions about the Baden-Clay 'dynasty' actually came from dealings with the Dickie girl from Redbank. Even Brookfield snoots have no time for people who hang their hat on what their great grandfather's second cousin's sister did, but they do appreciate nice, happy, honest people (despite gossipping about them at every opportunity).
Rumour has it a female showed sufficient poor judgment to allow this 'gentleman' to be intimate with her on a regular basis, outside his marriage. What could force a woman to stoop this low (Allison had an excuse because this was a man she betrothed her entire life to) is unknown. My guess is she's hit the 40's, without partner, been caking on the makeup, had limited joy on the dating scene, busy with work, made to feel important, so no biggie to lie down and take it - let's face it, a son in the dynasty they keep talking about - he should be great in the sack, if nothing else, even if he exhibits some effeminate characteristics. But, could be worse, who could she be hurting? (she now knows the answer to that question).
Affair exposed. Business completely stuffed. No more banging on chest saying 'look at me, I'm a big man on campus'. GBC would be feeling very exposed and vulnerable compared to the way daddy has told him 'stare fear in the eye son, that beautiful rare African cat stared at me and I blew it's face clean off - and I dropped a zebra from 20 paces then wore it's skin as a coat - THAT'S what makes a man young Gerard". (this imagined conversation is purely conjecture and I made it up - I have an idea how Bwana talks but pleased to say I have never had to listen to a long speech on his view of the world, a world where hanging remnants of a previously beautiful free creature on a wall is seen as a 'welcome to my home'). Sorry mods if you feel this is an attack on someone ... the behaviour is not typical in our community and deserves to be highlighted as unusual and unacceptable in this particular society.
If the poster who mentioned the couple have been in counselling was right, the couple's counsellor would have a lot if information (possibly given to police - not sure how patient confidentiality works there when police investigation involved). Counselling threatens typical males, because the whole Mars vs Venus thing makes it an uncomfortable experience. Men want to move on/forget it, women want to talk it out and get in touch with the emotions behind it. It's likely the counsellor would have pointed out the way Gerard has been told to behave that makes him a big man, is actually not appropriate in modern society. They probably pointed out Gerard has a responsibility to change his behaviour. Whether Gerard has come clean about the things making him feel inadequate or not is unknown. My guess is the outward Gerard shown, even to the counsellor, is not the real Gerard. To be asked to discuss issues every night (if this is what happened as a poster claimed) could possibly be belittling or infuriating. If these issues are true - running out of money, been caught out being unfaithful, spending time on big-noting positions of authority instead of being a husband and father at home - having to talk around Allison's feelings about these would lead to arguments, which could be the same arguments neighbours heard. IMO.
I don't think gullible financiers, parents, past (or present) mistresses or anyone else has been a party to the arguments (although they were probably discussed).
If one of these arguments escalated to something which caused serious harm being done to Allison, it's up to police to prove who did this and how. It remains to be seen if her husband is the sort of weak-spined coward who would hit or harm a woman. Nothing so far has proven that, although plenty of people have suggested it's likely. If there is any history of domestic violence, things look very bleak for him.
Slightly off the topic, I look at weak-willed spoiled brats like Matthew Newton, who smashes innocent people in the face then curls up in the foetal position next to them to say how much he is hurt too, and asking to please not say anything, he won't do it again. Then 3 days later he does the same thing to them or someone else. Why he comes to mind in this case, I'm not sure.
Remember it's taken something like 8 years to finally try the suspect in the murder of the Singh children, and they had a footprint and a bunch of obvious lies and inconsistencies in the suspect's story.
Allison's case is likely to take some time before enough evidence is gathered to identify and charge her killer. In my opinion it is only one person, acting alone, in an unplanned attack where things went horribly wrong. I think the fact police have interviewed 'numerous' people means they believe a lot of people know enough about the likely suspect's movements to put together a very solid confirmation about what exactly happened on the night Allison was killed and dumped.
