Downer’s history with Defence

Downer has been proudly supporting Defence for over 80 years. When you work with Downer Professional Services you harness decades of mission critical project management expertise from one of Australia’s largest sovereign companies.

Downer has provided manufacturing and heavy industry capability to the Defence sector since the 1940s when Evans Deakin Industries manufactured the Bathurst Class anti-submarine Frigates.

The breadth of our service offerings allows us to provide advisory and project delivery services to the same customer organisation. This provides value to Defence through the retention of project knowledge and early contractor involvement.
