- *The DIBP [19] statistics these population figures are extracted from refer to asylum seekers as “illegal maritime arrivals”. Total average population figures for the onshore immigration detention population displayed here vary slightly (by 1%) to those we have reported elsewhere [11] due to a lag in the DIBP’s reporting of figures for individual facilities and/or held detention types.** Wickham Point IDC did not record population figures from January 2015 onwards, so calculated episode rates are for a 5 month period only. *** A combined self-harm episode rate was calculated for APODs on the mainland, as well as for APODs on Christmas Island. Whilst APODs on Christmas Island were reported to have closed in late 2014, self-harm incidents were recorded as occurring in these facilities after this time
