pay each session only if you feel it was of value
Q: you probably want to find someone who is good at assisting you in assembling your very personal puzzle - how can you be sure you've got a well-trained and effective counsellor to work with?
A: a counsellor should be a registered member of a professional organization, such as those listed below. This helps to ensure the counsellor is academically qualified, participates in consistent professional development, and receives regular professional supervision sessions for themselves by a qualified counsellor or psychologist.
PACFA - Psychotherapy and Counselling Federation of Australia
ACA - Australian Counselling Association
QCA - Queensland Counsellors Association
AAFT - Australian Association of Family Therapy
Secondly, listen to your gut feeling. If it seems like a good fit for you after the first session or two, you probably have the right professional - otherwise try at least one or two others to help find someone who feels like a good fit. This will help ensure you get results that positively impact your life.
