Mel, one word of advice - RAAF! Do not bother with the Army. He will have better job satisfaction and its more family friendly. There is a reason why my DH is jumping ship. From memory he will be sponsored to finish his RN's through Uni and when he graduates he will go to RMC or Duntroon in Canberra for Officer training (as RN's etc are officers). He will have a roso (set term of service, usually training + 4 years but these days I think they are negotiable cause they are desperate!)

ETA - yep and recruiting lie, esp for the Army and they will often convince you to do some other job aside from the one your qual'd or looking for.
