The International Detention Coalition (IDC) is a not for profit network organisation based in Melbourne, Australia with a membership base of 300 non-governmental organisations, faith-based groups, academics, practitioners and individuals working in 50 countries globally. Coalition members research, advocate and provide direct services to and on behalf of refugees, asylum-seekers and migrants. The IDC is funded by the generous support of philanthropic organisations and individuals worldwide.

The IDC advocates for greater respect for the human rights of detainees; this includes preventing and limiting the use of, seeking alternatives to, and using the least restrictive forms of, immigration detention.

The IDC aims to promote greater protection of and respect for the human rights of those held in detention and to raise awareness of detention policies and practices. It also aims to promote the use of international and regional human rights standards and principles as they relate to the detention of refugees, asylum seekers and migrants. The Coalition reaches these objectives through networking, advocacy, raising public awareness and researching and reporting on issues world-wide relating to the detention of refugees, asylum seekers and migrants.
