I'm pretty sure that my attendance at Rhea's helped me get in to BMid first time around. I also think that being involved and a member of groups such as the ABA, Australian College of Midwifery and the likes helps alot. Showing a committment to birth/pregnancy related organisations, and being a passionate advocate for being 'with woman' impresses the Uni's I think. If you really want one of those sought after places, doing some birth attendance training can make a big difference, on a personal level and as to how the Uni see your perception of birth/pregnancy.
