A new posting can begin with a conversation between adults, a date on a form, or a small change in the way you speak around the dinner table. But children often notice the shift before they understand it. If you are wondering, what is an ADF posting, the simplest answer is that it is an Australian Defence Force member being assigned to a new role or location. For a family, though, it can mean far more: a new home, a new school, fresh routines, farewells, excitement and big feelings all at once.
A posting is part of service life, but that does not make it easy or ordinary for the children who live through it. Knowing what may be ahead gives families a gentler place to start the conversation.
What is an ADF posting?
An ADF posting is an official assignment that moves an Australian Defence Force member into a particular position, unit or location for a period of time. It may involve relocating within the same city, moving interstate, heading to a regional area or, in some cases, moving overseas.
The exact experience depends on the member's role, service, career stage and operational requirements. Some families receive plenty of notice; others may have less time than they hoped. A posting might mean the whole family moves together, or it may mean the serving member goes ahead first while housing, school arrangements or family circumstances are worked through.
Postings are different from deployments and exercises. A deployment generally involves a member being sent away for an operational purpose, often without their family. An exercise is usually a training activity that may last days, weeks or longer. A posting is about where the member's ongoing job is based. Of course, a posting can still include periods of field training, exercises or deployment, which is why it can feel difficult for children to know exactly what will change.
For a child, the word ‘posting’ may sound like a grown-up word with no clear meaning. They are more likely to be asking: Will I still see Dad at breakfast? Where will my toys go? Will I make friends? Can I visit Nana? Those questions deserve simple, honest answers.
Why an ADF posting can feel so big for children
Children do not measure change by removalist boxes or administrative deadlines. They measure it through the people and places that help them feel safe. Their bedroom, their kindy teacher, a favourite park, the familiar route to school and a best friend’s house can all be part of their sense of belonging.
A child may feel thrilled about a new adventure and sad about leaving at the same time. They may be proud of their parent’s work but angry that the family has to move. Neither response is wrong. Mixed emotions are a normal response to a significant change, and children need permission to have them without feeling that they are making life harder for everyone else.
Younger children may show worry through clinginess, disrupted sleep, toileting changes or more tears than usual. Primary-school-aged children may ask practical questions repeatedly, become quiet, or worry about fitting in at a new school. Older children may be concerned about friendships, sport, study or losing a growing sense of independence.
There is no perfect reaction to a posting. Even children who have moved before can find the next move hard, because every location, age and family situation is different.
Talking about a posting in child-friendly language
Once you have information you can share, tell your children early enough that they have time to process it. You do not need to have every answer before you begin. It is okay to say, “We know we will be moving because Mum has a new Defence job in another place. We are still finding out where we will live, and we will tell you when we know more.”
Try to use clear words rather than vague reassurance. Saying “nothing will change” can leave a child confused when almost everything around them does change. A more helpful message is: “Some things will be different, and we will work through them together. You will still be loved, cared for and included.”
Keep the explanation matched to your child’s age. A young child may only need to know that the family is moving to a new house because their parent has work there. An older child might appreciate seeing a map, learning the name of their new school or helping make a list of things they want to know.
It can help to return to the conversation many times. Children often think of their biggest questions while brushing their teeth, sitting in the car or settling into bed. Rather than treating these questions as a problem to solve immediately, make space for them. “That is a good question. Let’s find out together” can be deeply reassuring.
Preparing your family before the move
A posting comes with practical tasks, and involving children in a few manageable choices can help them feel less powerless. They might choose the colour of a new doona cover, take photos of their favourite places, help create a goodbye card for friends, or pick a special item to keep with them on moving day.
Be careful not to give children responsibility for adult decisions. They do not need to choose the suburb, manage the paperwork or carry your worry about housing and work. What they need is a role that says, “You matter in this family change.”
Routines are especially valuable while everything else feels unsettled. Keep regular meal times, bedtime stories and familiar weekend rituals where possible. If the move will separate the serving parent from the family for a time, make a simple plan for connection. Depending on the circumstances, that could be a bedtime voice message, a calendar for counting sleeps, a shared book read over video call, or letters and drawings kept in a special folder.
A visual countdown can help some children, but it is not right for everyone. For a child who becomes more anxious each time they see the date, focus instead on the next small step: this weekend we are visiting the new school; next week we are packing books. It depends on what helps your child feel informed rather than overwhelmed.
Supporting children after an ADF posting
The move itself is not the finish line. Often, the hardest part comes after the boxes are unpacked and the novelty has worn off. Children may need time to grieve their old life while they are being asked to settle into a new one.
Name what you notice without pressuring them to be positive. You might say, “It looks like you really miss your old friends today,” rather than “But you have new friends now.” Feeling understood usually comes before a child is ready to try again.
Help them maintain a few meaningful connections from their previous home, while creating gentle opportunities to meet people nearby. A play at the local park, a school activity, a sporting club or a Defence family event can be enough at first. New friendships cannot be rushed, and children do not need a packed social calendar to begin feeling settled.
It is also useful to let teachers, early learning educators and trusted carers know that your child has recently moved because of an ADF posting. They may notice changes you do not see at home, or be able to offer small supports during the school day. If worry, low mood, sleep difficulties or behaviour changes continue or become more intense, speak with your GP or an appropriate child and family support professional.
Making room for every family member’s experience
A posting affects the serving member, partner, children and wider support network in different ways. The non-serving parent may be carrying much of the logistics while managing their own work, friendships and identity. The serving member may feel pressure to settle into a demanding new role while wanting to be fully present at home. Children can pick up on this tension, even when adults are trying their best to hide it.
Small moments of connection matter. A family check-in over dinner, a walk around the new neighbourhood, or a weekly tradition that belongs only to your family can create steadiness. Stories can help too. Reading about characters who experience moves, separation and changing feelings gives children a safe way to talk about what is happening without having to find all the words themselves. This is the care behind Sea Sky Land’s books for defence-connected children.
There is no need to make a posting sound exciting every day. Children need truth, warmth and the confidence that their feelings have a place. When a family says, “This is a big change, and we will face it together,” they give children something more lasting than certainty: the reassurance that, wherever Defence sends them next, they remain unconditionally loved and heard.
