The Multicultural Communities Council of Illawarra Inc. (MCCI), formerly known as the Illawarra Ethnic Communities Council (IECC) was established in 1975 in Wollongong following the disbanding of the Good Neighbours Council.

The IECC operated from a small fibro home in Stewart Street later relocating to a heritage-listed property on 117 Corrimal Street in Wollongong, to accomodate expanding services.

The IECC recognised the importance of providing representation for the culturally and linguistically diverse  (CALD) and migrant communites in the Illawarrra. As a result, the organisation was formed with a strong advocacy and lobbying focus, hosting the first Aged Care Forum for Culturally and Linguistically Diverse communities in the Illawarra in 1984.

In 2009, the IECC relocated head office operations to Wollongong CBD and at the special members meeting was renamed "Multicultural Communites Council of Illawarra".

Following the success of the first Aged Care Forum in 1982, the IECC received the first funding "Grant-In-Aid" for a part-time Community Worker funded by the Department of Immigration and Ethnic Affairs.

In August, 1987, the Eastern European and Baltic States Aged Day Care Centre was opened by the Minister of Youth and Community Services, the Hon John Aquilina MP.

As one of the first ethnic specific day care programs in the region, the program highlighted the need for more ethnic-specific aged care services for the ageing (CALD) community.

In 1988 a number of additional language specific Aged Day Care Programs began in various community languages under the Department of Ageing Disabilty and Home Care, Home and Community Care Program.

Throughout the years the numerous MCCI programs and ethnic specific Day Cares have significantly increased. We currently run over 14 Centre Based Day Cares, have an extensive range of short and long term youth programs, program for the elderly as well as programs that provide information to our CALD communities or to services that are in contact with these CALD communities.
