General notes:
Agencies dashboard:
- The PHN of the agency was assigned based on the Statistical Area Level 2 (SA2) of the treatment agency using the Australian Bureau of Statistics' (ABS) SA2 2016 to Primary Health Network 2017 concordance file.
- As SA2 2016 boundaries may not correspond to PHN 2017 boundaries, some agencies may be captured in a neighbouring PHN including those in a neighbouring jurisdiction.
Main treatment for client dashboards:
- The PHN of the client was based on the postcode of the client using the Australian Bureau of Statistics' (ABS) Postal Area 2016 to Primary Health Network 2017 concordance file. Clients reporting an invalid postcode were assigned: 'PHN Unallocated' and removed from analysis. In 2020–21, 10,587 records contained invalid postcodes.
- Results with cell sizes less than 5 have been presented as '<5' (in some cases the value is null), due to this adjustment some values may not sum to the total or 100%.
- Data collection and reporting practices in Western Australia and Victoria are not directly comparable with data for other jurisdictions because every treatment type provided is reported as a separate episode.

Principal drug of concern dashboards:
- The PHN of the client was based on the postcode of the client using the Australian Bureau of Statistics' (ABS) Postal Area 2016 to Primary Health Network 2017 concordance file. Clients reporting an invalid postcode were assigned: 'PHN Unallocated' and removed from analysis. In 2020–21, 9,625 records contained invalid postcodes.
- Results with cell sizes less than 5 have been presented as '<5' (in some cases the value is null), due to this adjustment some values may not sum to the total or 100%.
Jurisdiction-specific notes:
- Victoria reported comparatively high incidences of ‘Not stated drugs’ (15%) as the drug of concern. This is in part due to service providers adjusting to changes in reporting practices associated with the implementation of a new data collection system in 2019–20. In 2020–21, these drugs of concern were coded as ‘Other drugs of concern’ (14%) to realign with previous coding practices for Victoria. Victoria is working with service providers to encourage more specific reporting of drug of concern.
- In Queensland, the level of cannabis reported as the principal drug of concern is a result of police and illicit drug court diversion programs operating in the state.
- South Australia reports a high proportion of treatment episodes where amphetamines are the principal drug of concern due to the SA Police Drug Diversion Initiative (PDDI). In addition, adult cannabis offences are not included in the PDDI due to the SA Cannabis Expiation Notice legislation.
