Doomsday cults are often the most destructive as they have greater power over members due to the imminent end of the world. Once members buy into a doomsday predication, they are more easily parted with things they will not need in the post-apocalyptic world, things like money, property, a university education, friends and family not in the group, etc.
AJ Miller claims that movement of tectonic plates will cause catastrophic "Earth changes" and will result in a dramatic rise of the oceans. Both the East and West coasts of Australia will be under water about 100 meters deep. He states that major cities such as Brisbane, Sydney, Melbourne and the Gold Coast will no longer exist.
The Wilkesdale/Kingaroy area where his compound is located, will undergo a majestic change from rural to sub-tropical. Miller claims the "Earth changes" may start as early as 2012.
Real Estate agencies have reported a boom in property sales due to Miller's followers selling their homes and relocating to the Wilkesdale/Kingaroy area. Miller, when asked why his followers were moving to Kingaroy, had no idea.
I do, however, respect (that's too strong a word)... disrespect him ever so slightly less than I disrespect other cult leaders. At least he's open about his ridiculous claims. That makes a refreshing change from the Korean messiahs I follow (as in keep track of, not actually "follow" follow) who reserve their own ridiculous claims until well into the indoctrination process.
He does say in the above video that donations are his only form of income, so I think we can classify him as a financial exploiter. All this nonsense about not seeking money from followers is, well, nonsense. Once you have someone believe you are Jesus, gaining their money is easier than taking candy from a baby. Much, much, much easier.
