Complaints rise on immigration detention

Complaints about alleged human rights breaches jumped by more than a third over the past year, mostly relating to immigration detention.

The Australian Human Rights Commission received 485 complaints in 2014-15 - up from 355 in 2013-14, according to its annual report tabled on Monday.

A majority of them (80 per cent) were against the federal government's Department of Immigration and Border Protection, while the others related to employment and workplace discrimination.

In cases where the commission can't resolve a complaint through conciliation, it prepares a report for the attorney-general.

A total of 22 reports were presented in 2014-15 involving 43 individual complaints.

"The human rights breaches found against the Commonwealth principally related to individuals detained in immigration detention centres, including the right to liberty and to be free from arbitrary detention," the report said.
