McConnell Dowell refined the initial concept design and is now constructing a new outer wharf structure at HMAS Coonawarra in Darwin to support the Australian Defence Force. 

The project involves the construction of a new 250 m long wharf and two approach jetties. Once completed, the facility will provide additional berthing and support services for Royal Australian Navy vessels. 

McConnell Dowell’s project scope is part of a broader upgrade currently underway at HMAS Coonawarra being undertaken by Laing O’Rourke Australia Construction, as part of the Larrakeyah Defence Precinct Redevelopment Program (LDPRP).

Works are underway with McConnell Dowell’s scope scheduled for completion in the second half of 2022. Subsequent associated wharf services and infrastructure packages will be tendered separately and are scheduled for completion by mid-2023.
