I have not heard of this organisation before, but I did a little research after reading your message. I noticed that The Dream Centre is active on the Gold Coast, which is cult central for Australia.
Personally I think that the following account is disturbing and sugguesstive of a charismatic leadership and potentially a dangerous cult.
Ps Rod Gilchrist announced on the previous Thursday in Perth he
went to heaven for 4 hours. Many people have heard about this since. This is what I roughly hand recorded in my journal and newsletter Sunday 27 May 2001 being at all 3 services and then Monday night 28 May 2001. It was because of this event that the name of the church was changed to "The Dream Centre"
If your daughter has agreed to wait as you asked her to then it would seem that she has good critical reasoning still intact - ie she is willing to seek other sources of information.
I think that you should have a talk with her about what destructive behaviour is and what the consequences can be. You may be able to raise with her the possibility that this is a cult, although most cults have readily available answers as to why they do not fit this definition and rationalise it as prejudice, misunderstanding etc.
If she could be aware of the sorts of behaviours that cults engage in, isolation, saying that all other religions are wrong, limiting access to information, maintaining that the leader is beyond any question, giving over money and/or posessions, having no contact with outsiders giving up family relationships etc. then hopefully if she does still choose to go then her critical reasoning will remain intact.
You may want to search the database here for other Christian based organisations and discuss the points of similarity there with her or have her read some of the articles or read through them together.
Maybe you could try honestly stating to her your concerns, that she may be harmed by this organisation, that you may lose contact with her, or whatever they may be and ask her the reasons why she has to go away with them, why she can't participate from where she is or at least have more experience of them before diving into that. I made this mistake myself the reason being that I had to go where I went to access the teachings and associate with others, there was no other option and it was what I really wanted. Only what I saw through experience and the way I was abused there made me realise it was a mistake, and even then the truth is that had circumstances not transpired to break up the relationship that I was in with another cult member because of their beliefs I would most likely have been there a lot longer and learned how to turn a blind eye to the negatives like the others there do. I am not faithless now thinking that searching for faith is a negative thing for anyone, I just don't like the idea of anyone being hurt by similar circumstances. I know my life would have been hell if I was still there, but in all honesty it is the most likely decision I would have made.
I know from experience that one does not have to be on a commune or physically restrained to get caught up in a cult and for it to have a destructive influence on their life, but if someone had told me this about the cult I was going into I would not have believed it. Being physically free to go at anytime does not mean that you are psychologically or emotionally free to go once you have been under their influence.
I do imagine that having someone on the 'outside' who is personally supportive and available if things go wrong would make a big difference.
There may be nothing sinister at all about this group, but it certainly does not hurt to be aware. I wish you and your daughter all the best.
