Credo is affiliated with Christian groups at many other universities through the Australian Fellowship of Evangelical Students (AFES): http://www.afes.org.au
AFES is a fellowship of Christian University Groups, and is purposely interdenominational. It has a strong Bible teaching ministry, which aims to set forth Christ to an unbelieving university and to equip Christians for a life in His service.
Credo is also affiliated with the UTS Union. UTS Union aims to foster a strong social and culturally diverse environment on campus and provides assistance to clubs and societies to further this aim. http://www.utsunion.uts.edu.au/
