For Shaqaeq, whose family fled Taliban-controlled Afghanistan, going back home would mean certain death. Shaqaeq's family are Hazara, a religious and ethnic minority persecuted by the Taliban.
"My family, all of them, I don’t want to say it, but we would probably be murdered or severely, severely persecuted by the Taliban," Shaqaeq told SBS Voices.
George, an Armenian Christian refugee from Syria says returning there would mean risking kidnap and ransom as civil war rages under the brutal Assad regime.
"They might kidnap me and ask for ransom. Millions of dollars in Syria, they [would be] asking...or I might get killed," he said.
"I am just going to see blood there. I’m just going to see sad faces. I’m just going to see disappointment."
For Roza, an ethnic Kurd, the lack of guarantees for the historically persecuted community has meant living in a constant state of insecurity and turmoil.
"As Kurdish people there’s never a guarantee for your life. People do not know what tomorrow will bring, politically and militarily in the region."
