AOD reporting in Western Australia, explained.
A plain-English overview of alcohol and other drug treatment reporting in Western Australia: who collects the data, what is involved and where Mimaso fits.
General information only. This guide is a plain-English overview, current as at November 2026. It is not legal, compliance or professional advice. Confirm your obligations with your funder and the current official documentation.
Where this applies: Western Australia (WA).
Who collects the data?
In Western Australia, alcohol and other drug (AOD) treatment data is collected by the Mental Health Commission rather than the Department of Health. Services it contracts to deliver AOD treatment include the national AODTS-NMDS items in their data, and the Commission supplies the data to the Australian Institute of Health and Welfare (AIHW) each year.
Services funded only by the Australian Government, including through a Primary Health Network (PHN), generally report directly to the AIHW.
What is involved?
- Contract requirements. Your contract with the Commission sets the data items, format and timing.
- Your own system. Since the central SIMS system closed in July 2021, services report from their own client management systems.
- Annual changes. The national specification is reviewed for each financial year, and your system has to keep up.
Where Mimaso fits
Mimaso is set up for Western Australian AOD reporting. Your team records casework as usual, and Mimaso produces the return, flags missing or invalid fields as they are entered and checks the whole return before it is submitted.
