In 2016–17, counselling was the most common type of main treatment in Western Australia (66% of episodes), followed by withdrawal management (7%), and pharmacotherapy (7%). (Figure 15; Table ST.5). Due to the nuances of Western Australia’s data collection system, with each type of treatment resulting in a separate episode, Western Australia cannot supply data on additional treatment types.

Over the 5 years to 2016–17, counselling remained the most common main treatment type for closed episodes in Western Australia. Withdrawal management remained the second most common main treatment type, although the proportion of closed treatment episodes for withdrawal management has decreased since 2012–13 (14% to 7% in 2016–17). The proportion of episodes where counselling was a main treatment type (ranging from 60% to 66%) remained substantially higher than the national average (from 43% to 36%) (Tables SE WA.20 and ST.2).
