The hospital i go to has a birth plan in the info that you get, i have filled it in twice and both times it has sat in the front pocket of the bag. DF knows what i want, or i ask him, with the major things like in the event of a emerg c/s he knows what to do, he asks me if i want any pain releif (most of the time its from him rubbing my aching back!!) Also the midwives that are at wollongong hosp are excellent, they listen to your needs/wants. Make neccesary comments/advice. The midwife i had with Jett was excellent, i actually gave birth with a heat pack on my back!! Hehehehe.
Goodluck and make sure you discuss with your DP/F/H What your intentions are!!
