"Unlawful non-citizens" to be detained, regardless of circumstances, until they are granted a visa or leave the country. This policy was introduced in 1992 and has been maintained by successive governments.
Impact in metal heath-
Uncertainty about their future, lack of independence and loss of control over their lives, the monotony of life in detention, concern about family members still living in dangerous situations overseas, the impacts of past torture and trauma and witnessing the negative impacts of detention on other detainees all contribute to the deterioration of mental health and wellbeing.
Detainees may experience a range of mental health issues, including depression, anxiety, cognitive problems, difficulties regulating their emotions, consistently behaving in a way that is not characteristic or normal, sleep-wake cycle reversal, self harm and indefinite detention can lead to suicide.
Immigration detention facilities in Australia-
Immigration Detention Centers (IDCs), high-security facilities designed for a range of "unlawful non-citizens" including visa overstayers, people who have breached their visa conditions and asylum seekers who arrive without visas. There are currently seven IDCs operating in Australia, including six mainland facilities in Curtin, Darwin, Maribyrnong, Northam, Perth and Villawood, and one offshore facility on Christmas Island.
Immigration Residential Housing (IRH), domestic-style accommodation which is usually used for families and allows people in detention to have a degree of autonomy (e.g. cooking their own meals). IRH facilities are located in Perth and Sydney.
Immigration Transit Accommodation (ITA), hostel-style accommodation for people who are considered to be a low security risk and whose status is likely to be resolved quickly. ITA facilities are located in Adelaide, Brisbane and Melbourne.
Alternative Places of Detention (APODs), lower security facilities
