Alan, what a fantastic offer that is.
Min, I am not sure that a public hospital can actually stop you from doing a VBAC. If you don't agree to an elective c/s and you have been going to their midwife clinic (sorry making assumptions that is what you are doing) and you turn up in labour, then they can't turn you away. But of course that would be a very stressful situation. My understanding is that you can't actually elect which OB you are admitted under in a Victorian public hospital, you just get who is on when you arrive there so it would be awful for you to be wondering if you were going to get one of the doctors you don't want. You would certainly need someone like Alan with you, who could get your point across strongly.
sorry I am not much help but want to add my support as it must be very distressing to have things change so much at this stage of your pregnancy.
