'll try to answer your question and maybe someone else will help with more info.
For questions 1 and 3 I would contact the French Embassy in Sydney if there is one or the nearest embassy/consulate/ambassador/government representative. Or find a French restaurant run by French people and see what they can tell you. I know you aren't the only one wanting to work in France so they have pretty strict policies about allowing foreigners in.
2. Once you have worked out details on getting there, you should have a pretty good idea of what they expect. I think they will most likely start you with simple things to see where you are and what your attitude is like.
If you manage to pull this off and actually find yourself in France working in a patisserie, keep you eyes open. Don't worry so much about what you are doing, worry more about what you are seeing, hearing and experiencing. You can learn a lot by observation and a few well placed questions.
