About GDHC

Global Disaster Health Consulting (GDHC) is a pioneer and innovator in evaluating health system responses to public health emergencies, catastrophes, and natural hazard disasters. We identify opportunities to design cost-effective ways to improve the effectiveness and impact of emergency health responses.

As natural hazard disaster events continue to rise exponentially in all countries, the importance of accelerating the capability, capacity, and quality of healthcare to affected communities has never been more vital.1

Our Values


Global Disaster Health Consulting maintains strict governance and operational independence. We are not incorporated or aligned to any organisation, government, or multi-lateral agency. Our approach is not constrained by any single philosophy, worldview, or policy position. We create open, flexible, and engaging processes which recognise and respect local customs, build trust, and strengthen relationships across the multi-dimensional layers of emergency and disaster health response organisations.


Innovation adds value. GDHC supports and enables innovative processes and practice to respond to disaster events at the interface where local health services care for communities to improve access, equity, and the quality of healthcare for all people. We discover local innovation within local service delivery process and practice that significantly improves efficiency, effectiveness, and reach. We use co-design and collaborative methods to identify improvements readily implementable.

Scientific rigor

We use an objective and meticulous process in the design, analysis of information, reporting bias and confounding and the documentation of our process, results, and recommendations. GDHC is committed to enabling the replication of any methodology and method to ensure reproducibility of any result. Similarly, we are committed to incorporating and sharing contemporary scientific peer review of improvements in process, policy and practice in our analysis, review, and recommendations.

Context specific

Every disaster and catastrophe is unique and affects people and communities in different ways. GDHC grounds every analytical approach with a comprehensive context analysis, including internal and external factors. This ensures the influences, barriers and challenges effecting emergency health responses are identified and mitigated to sustain health service delivery to the most vulnerable people.

Our Approach

Global Disaster Health Consulting works in collaboration with clients and stakeholders to identify and co-create high impact and cost efficient improvements to disaster and emergency health response using existing resources.

We offer a comprehensive suite of bespoke services and tools to critically examine, test and improve health system planning preparedness and response activities to health emergencies, catastrophe and natural hazard disasters in any country and every local context.

Our Leadership

Global Disaster Health Consulting was founded by its Principal, Dr Gerard Finnigan, with the objective of creating an independent expert advisory service to support countries reduce their morbidity and mortality risk from health emergencies and disasters irrespective of available resources or challenging local context.

Over 20 years of professional practice in international development and humanitarian response, Gerard observed that well-meaning advice provided to health systems was not always evidentiary, adaptable, or appropriate for the local context or country situation. Typically, misguided advice effected the impact of the emergency response and the quality of healthcare in situations where health risks were changing and increasing in complexity. Conversely however, where advice promoted local partnerships and collaboration and prioritised innovation of existing health service policy and practice, emergency health responses improved outcomes for affected communities and local healthcare capacity was strengthened.

GDHC believes significant improvement in emergency and disaster health responses is achievable and can be fast tracked in every county context with support by dedicated teams of independent, internationally trusted experts with extensive experience working with local health services and communities.


Australian First Nation peoples managed and cared for the natural environment with such skill and knowledge to ensure it remained a healthy and productive continent for millennia. Critically though, their Law and knowledge protected country and all things that existed within her – animate and inanimate1. With the planet facing the triple crisis from climate change, pollution and biodiversity loss, the immense wisdom of Australia’s First Nations peoples and oldest continuing living culture is as relevant today as 60,000 years ago and essential for the survival of all things.

GDHC acknowledges the Traditional Custodians of the lands on which GDHC is based, including the Wadawurrung, Wathaurong, Wathaurung, and Wadda Wurrung peoples, and their connections to land, waterways, and community. We pay our respects to their Elders past, present, and emerging and all Aboriginal and Torres Strait Islander peoples. We acknowledge sovereignty has never been ceded and it always was and will be Aboriginal land.

We support the Voice to Parliament for Australian First Nations peoples.
