With the overarching goals of promoting our Sister City partnership and uniting our world, the San Diego-Perth Sister City Society focuses on making connections through education, arts, culture, and economic development. We believe in an international environment of peace and cooperation that welcomes all races and creeds and promotes the acceptance of diversity. Fostering this environment helps cultivate leadership and communication skills to break down the misunderstandings that often lead to conflict.

Our specific programs are designed to help develop a lifelong global perspective in our community’s young people, expand our city’s influence on the national and international stages, and boost our local economy – all in service of the larger goal of creating a more peaceful world.
