In my experience I would say that JWs in Australia would resist blood for thier children, at the instruction from their leaders at world HQ, and most are not aware that doctors will give blood to a minor anyway....
Back when I was still in the cult, I had one elder try and tell me we can refuse blood for our children, and I was trying to tell him otherwise but he had a WT education. My child had been under intensive care for a week, and received multiple transfusions, so I didn't argue with the fool I just left him in his ignorance. He like many others, are under the wrong impression about laws regarding blood transfusions and children with cult parents.
