Our history began in 1934 when MacDonald Wagner formed in Sydney, Australia. In 1989, a merger with the Connell Group formed Connell Wagner. The Aurecon brand was created in 2009, through a merger of Connell Wagner with two African based businesses.

In October 2019, faced with changing conditions in Africa, where global models are no longer considered an advantage, Aurecon decided to demerge its African business.

Aurecon retains a strong international presence with businesses across Australia, New Zealand, and Asia.
