Cambodia is a country continuing to work towards addressing its challenges. Whilst having benefited from three decades of relative stability after civil war and the 1970s genocidal rule of the Khmer Rouge, health and education remain important challenges and development priorities.

Our Work

EWB Australia works to improve the quality of life of people living and working in disadvantaged communities in Cambodia. Our work is impact-led, with a focus on positive, sustainable and long-term change. We do this within local communities, to ensure we build the capacity of the people who live and work in them. Through this approach, we have established long-term relationships with local organisations with whom we partner, to ensure the solutions developed are evidence-based, relevant and, importantly, approved by each community. 

In Cambodia, we work across a specific range of thematic programs, including Water, sanitation & hygiene (WASH), Education & TrainingEngineering Education, Inclusive Design and Clean Energy.

Our Impact

EWB Australia in Cambodia is currently engaged in a range of technical solution and sector & systems-strengthening projects.

    Our Team

    Key to this work are our in-country EWB Australia staff and our volunteer Field Professionals.

    Our Field Professionals are technical or thematic specialists who volunteer to work in-country to provide critical expertise, mentoring and capacity-building. These technical professionals are not only skilled in the development of appropriate systems and solutions, but also in community-led design and engagement. Our Field Professionals work alongside our in-country staff, or within our local partner organisations. Via this collaborative response, we enable and empower remote Cambodian communities to only tackle the issues that are relevant and of priority to their communities.
