Elizabeth Cosson - ADF Service

ADF Service

Elizabeth (Liz) Cosson joined the Australian Army in 1979 as an officer cadet and was commissioned in the Royal Australian Army Ordnance Corps. During the early part of her career she held a number of appointments as a supply and administrative officer.

In 1991 she was appointed to a position at the Royal Australian Air Force Logistics Command where she was responsible for the logistics support to army aviation aircraft. For her work in improving the availability of the UH-60 Black Hawk helicopter fleet and supporting the fleet deployment to Cambodia, she received a commendation from the Air Officer Commanding Logistics.

In 1995 Cosson served in a number of appointments within Land Command, including a regimental appointment with the 11th Brigade and a logistics staff officer appointment at Headquarters Land Command. During this appointment her responsibilities included logistics planning in support of the 1999 operations in East Timor. In November 1999 she deployed as the Chief of Staff of the Peace Monitoring Group, Bougainville.

She was awarded the Conspicuous Service Cross in the 2001 Australia Day Honours List "for outstanding achievement as the Chief of Staff, Peace Monitoring Group, Bougainville, and in logistic planning and management of the Combat Force as the Staff Officer Grade One Logistics, Land Headquarters".

On her return from Bougainville she served with Defence Corporate Services before being seconded to the Joint Standing Committee for Foreign Affairs, Defence and Trade in the House of Representatives. In 2002, Cosson commenced a three year appointment in strategic logistics planning and was responsible for logistics policy and for developing concepts to improve logistics information systems.

In December 2005 she became the first woman to be promoted to the rank of Brigadier in the Australian Army.

She served in the Corporate Services and Infrastructure Group of the Defence Department as the Director General Regions and Bases. In this position she was responsible for the management of integrated service delivery to Defence bases across Australia.

In March 2007 she assumed the role of Head Defence Support Operations in an acting capacity. In November 2007, the role was confirmed and she became the first woman to be promoted to the rank of major general in the Australian Army. She is the second female to be promoted to two-star rank in the Australian Defence Force, the first being Air Vice Marshal Julie Hammer, who retired in 2005. Cosson, as head of National Operations within the Defence Support Group, became responsible for the management of 80 ADF bases and garrisons across the country. At that time, although about 13% of the ADF were women, there were only four at the one-star level: Commodore Robyn Walker, Commodore Vicki McConachie, Brigadier Lyn McDade and Air Commodore Margaret Staib.

Cosson was appointed a Member of the Order of Australia in the 2011 Australia Day Honours List as a result of her "exceptional service" in the positions of Director General Regions and Bases, and as Head Defence Support Operations. In December 2010 it was announced that she had been appointed General Manager of the Executive Division of the Department of Veterans Affairs.
