Media reports (see below) cite the occurrence of potential health risks to refugees, asylum seekers and staff caused by a mould problem at the offshore immigration detention centre operated by Broadspectrum (formerly Transfield Services) on Nauru.

Business & Human Rights Resource Centre invited Broadspectrum to respond to concerns about health risks to occupants and staff at the centre. A company spokesperson for Broadspectrum responded that it "maintained a safe and healthy workplace for its employees while working at the Regional Processing Centres until 31 October 2017."
