Manly Council and Gunnedah Shire Council signed a Friendship Relationship agreement in September 2005. Manly amalgamated with Pittwater and Warringah councils to become the Northern Beaches Council in May 2006.

The partnership was formed to develop a close friendship and bilateral exchanges in culture, education, environment, sport and literature, including a common interest in our shared citizen, the famous poet Dorothea Mackellar.

In 2010, Manly Council hosted a group of Gunnedah students as part of the Bush to Beach student exchange program, and Gunnedah in turn hosted a group from Manly.Northern Beaches Council also hosted farming families for a beachside break during the difficult years of the drought, showing how practical and meaningful a Sister City partnership can be during tough times.
