In addition to a growing epidemic of HIV among transgenders in Thailand, a low awareness of how to access justice increases their vulnerability to HIV infection. This paper presents a unique case study of how one community-based and led organisation used social networking and instant messaging to address this problem among the transgender community in Thailand. It describes and analyses how online peer-based health counseling integrated HIV education and prevention alongside access to justice through free university-based clinical legal education (CLE). It argues that a community-based approach that integrates HIV prevention and education and access to justice within a wider sexual health programme, through digital technologies, is a sustainable approach for other populations disproportionately at risk of HIV. Furthermore digital media offer strategic opportunities to overcome on-going political violence alongside entrenched stigma and discrimination that disrupt denial of access to justice.
