I initially started seeing my T in a funded community practice and my sessions cost $18 for 90 minutes, twice a week. Eventually she moved into private practise and she charged most clients $150 per 50 minute session, but she continued to see myself and a handful of clients from the community centre at our previous rates. When I moved into full time work I paid $40 each for two 90 minute session per week.
