The Josephite Justice Network has launched Tuesday Mourning, a weekly event from now until Pentecost Sunday in mourning for the innocent people locked up on Manus Island and Nauru.
"Hundreds upon hundreds of innocent people, are locked up," the Sydney-based network says.
"They have committed no crime. They have been charged with no crime. They have been locked up for years.
"Innocent people. Locked up. For us.
"Join in with Tuesday Mourning," the organisers say. "Wear black. Wear a black ribbon. Wear a black armband. On Tuesdays.
"Every Tuesday until Pentecost Sunday. Mourn for the innocent victims locked up. Locked up for us. For Australian fear.
"Between 2013 and 2016 the federal government spent $9.6 billion on mandatory detention and offshore processing," the Network says. "Another $5.7 billion is planned to be spent up to 2020.
"During the same time, the UNHCR cost of supporting over 60 million refugees and asylum-seekers in Africa, the Americas, Europe, the Middle East, Asia and the Pacific was just over $3 billion per year, increasing to $7.5 billion in 2016."
