A/HRC/35/25/Add.3 127. Simplify and encourage civil society organizations’ access to detention centres in order to reinforce the information that migrants need in order to make appropriate choices regarding their legal options. 128. Ensure that detention appeal proceedings allow for a regular review of the merits of the detention, and not only of its legality. E. Cross-cutting concerns 129. Provide access to basic services such as health care to everyone living in the Australia, regardless of their immigration status, in accordance with international human rights standards. 130. Implement “firewalls” between public services and immigration enforcement, thereby offering better access to effective labour inspection, access to justice, and access to other public services such as housing, health care, education, and police and social services, for all migrants, regardless of status, without fear of detection, detention and deportation. This would also allow for better collection of disaggregated data by government agencies, especially on undocumented migrants. 131. Ensure respect by all service providers in onshore and offshore detention facilities of the Guiding Principles on Business and Human Rights, adopted in 2011 by the Human Rights Council, which underscore as one of their foundational principles the corporate responsibility of business enterprises to respect human rights. 132. Ensure effective enforcement of laws prohibiting racist and xenophobic acts as well as hate speech and racially motivated violence against migrants and asylum seekers. Ensure that such acts are prosecuted and punished and that appropriate compensation is awarded to the victims. 133. Strengthen the efforts to apply the legislation in order to combat direct or indirect discrimination with regard to the enjoyment of economic, social and cultural rights by migrants, refugees and asylum seekers, including in access to private rental housing and to the labour market. 21
