Mr Armstrong's early career in fire management involved fire suppression activities as a front line fire fighter, and a practitioner of prescribed burning in the south-west of WA. He subsequently developed additional skills, knowledge and experience in fire management that has enabled him to fill senior roles in fire suppression organisations.
He has led multi-agency incident management teams from Western Australia to other Australian states to provide assistance under mutual aid agreements. These include deployments to the Victorian Great Divide complex of fires in late 2006 and the Victorian Black Saturday fires of February 2009.
His proven skills, experience and leadership have also seen him chosen to be part of, or a leader of, several deployments of fire managers from across Australia to provide aid during severe fire crises in the Pacific North West of the USA. This is testimony to Mr Armstrong's professionalism and effectiveness, his essential skills of leadership in times of uncertainty, empathy with both responders and affected communities, and the ability to work effectively with a broad range of people with different interests and priorities.
His service over two decades as a senior and respected Incident Controller has been of immense benefit to fire services.
