Pernitsch, you will have the opportunity to request Married Quarters once you receive a posting after your training. Once you have secured accommodation she can move to join you at your new base. All of our bases now have Military Family Resource Centres that are very good places for the wives to learn much about their new area and the resources available to them, both military supported and in the surrounding civilian community. You can visit the local MFRC even while you‘re on basic training (when your schedule permits), they may even provide counselling in the evening, to help you better understand what you can expect for you and your new wife in your first posting.
