Hi Loneranger
Sorry for taking so long in replying, i was busy building the "How to immigrate" section of the website, hope you like it!
I can understand your concerns and how anxious you want to be with her, you are correct in the assumption that your best visa would be prospective marriage, the good news is that it is one of the "priority" visas and the speediest way to prioritize it is to set a date for the marriage in Australia and book a hall and have proof of all other marriage preparations to be presented to the department of immigration here in Australia.
She should fill out the forms and send them to you (including the marriage bookings etc) and the assurance of support (basically a declaration stating that she is willing to be responsible for you in Australia. then you fill out the rest of the forms and lodge the entire application in the nearest Australian Embassy.
If you have more questions regarding a different subject please post them in a new thread and good luck and keep us posted on this relationship
