Network Ten and many of its top presenters are lending their support to an international effort to reduce discrimination against gay, lesbian, bisexual and transgender (GLBT) people.

To mark the International Day Against Homophobia (IDAHO) on May 17, selected Network Ten personalities will appear in a special 30 second advertisement encouraging people to get involved in This Is Oz, an online photo gallery where participants can upload pictures of themselves with messages that challenge homophobia or celebrate diversity and social inclusion.
