Notes:
1. Each state and territory uses a different method to collect data on pharmacotherapy prescription and dosing. These differences may result in minor discrepancies if directly comparing one jurisdiction with another jurisdiction.
2. In Western Australia the number of clients receiving pharmacotherapy treatment are reported through the month of June. Before 2005, Western Australia reported clients over the the whole year.
