The website, www.otdfpng.org, is designed to attract donations plus provide materials such as school resources or sharing knowledge to suitable volunteers.
"OTDF has grown rapidly in the last two years and has an enormous obligation to address the dire social and developmental issues faced by the people of Western Province," OTDF chief executive officer Ian Middleton said.
"I hope that this site provides an opportunity for interested individuals and organisations to work with us to deliver real change for these people.
"This site will inform key agencies within the country of the need for support, that there is a genuine delivery partner working at the ground level but also attract donations from abroad with an assurance that their contributions will flow directly to those people that really need it," he added.
"We are serious about development and we have shown that through the many projects we are doing in livelihood development, accessibility, health and education. This is not just an ordinary website, but a means to foster greater partnership with individuals and organisations that want to hold hands with us to ensure the self-sustainability of the Western Province communities, specifically those within the community mine continuation agreements."
The direct donation link will be launched on the site by year end.
