Hmmm..... not sure where I fit in. I'm a BB'er, but not Australian. Not American either.
Anyways, here's my list:

DD1 (pre-BB) - waters ruptured spontaneously at home in early labour, laboured without augmentation, received a nubain shot at 7cm, delivered naturally, without tearing, received oxytocin for placenta.

DD2 - waters broken in hospital at 5-6 cm at my request, laboured without augmentation, received demerol shot, delivered naturally without tearing, received oxytocin for placenta.

DD3 - home waterbirth. pre-labour all day, until waters broken at my request, delivered naturally 2 hours later, no tearing, no pain relief meds, received oxytocin for placenta.

DD4 - hospital birth (GBS+ ) pre-labour all day, four hours of true labour, "had" to have IV antibiotics in labour, waters broken at my request, no pain relief, delivered naturally, no tearing, received oxytocin for placenta.

DS1 - home birth. prelabour all day, stretch and sweep at my request, true labour started, waters broken at 7cm at my request, pushed for 1 hr, and delivered a brow presentation posterior baby, without tearing, received oxytocin for placenta.

So I guess I've had some interventions, but nothing I didn't consent to, which I'm grateful for, and I have pushed all my babies out without augmentation, epidural, episiotomy, forceps, ventouse, etc.
