Some are mothers who have fled arranged marriages and international students who would rather die of shame than tell their families.
They are homeless, like Bikram Lama, who The Guardian reported to be a former international student from Nepal. His death outside St James train station has shone a light on an invisible situation taking place on Australia's streets.
These homeless are not citizens, and they don't have permanent residence, but they are stuck here, unable to return home or waiting on seemingly endless temporary visas, hoping Australia will allow them to stay.
