OK, then I'd suggest that you get a good 66 Mustang restoration book. Perhaps chase one down on line from a motoring bookshop in Sydney.
That book will tell you what tools you'll need, if you don't already have them, and things such as a trolley jack and safety stands.
Then start making a list of the things you want to achieve, and break that down into sub-sections on the bodywork, trim, drive train, mechanicals etc. Then you have a written plan, which you can update if needed as you go along.
Have a digital camera and PC handy, and take heaps of photos of everything before you dismantle it and file them.
Collect some boxes for storing parts, and clear plastic bags for individual bits. A packet of sandwich bags from the supermarket takes care of all the small things. Label each bag with a texta as to what and where from. Keep all the old parts until you get new items, so you can assemble from the old labelled parts.
Believe me it's impossible to remember how it all goes back together again after a few weeks.
Establish an adequate budget, and prepare for unexpected costs. There's nothing more frustrating than seeing a nearly finished car awaiting those last few dollars to complete. Rebuilds always take longer than expected too.
That gets you started until some of the Sydney people take up the running.
