Mentally ill public housing tenants in Sydney’s west risk developing post-traumatic stress disorder (PTSD) from living in dangerous environments, according to a former health worker at Mount Druitt Community Health Centre.

"Public housing in places like Mount Druitt and Blacktown are not a good environment for people who suffer from mental health issues such as depression or anxiety disorders," says Ben, who can’t reveal his name due to a clause with his NSW Health contract.
