Counselling is available at both Direction ACT offices at 1 Bradley Street Woden [1] (the old police station) and at City Health Building [2].
While appointments are not always necessary, for instance if you are in a crisis situation, it is wise to book for appointment to ensure the time that suits you, and you have the counsellor of your choice.
