Australia's former prime minister and the Work singer shared the spotlight in New York City on Saturday evening local time as part of the Global Citizen Festival. Their unlikely partnership is in aid of a new Global Citizen education initiative, which was officially launched at the concert after performances by Metallica, Chris Martin, Eddie Vedder, Kendrick Lamar and Bill Nye.

Monocle's annual survey on soft power - assessing the influence of nations in spheres including politics, diplomacy, business, culture and education - names Australia as the fifth-most influential nation in the world and singles out Mr Rudd's performance on the global stage in explaining its decision.

The broadcasts are a powerful tool of public diplomacy, furthering and promoting our foreign policy and national interests through the dissemination of ideas, information, values and beliefs and building greater understanding among the billions of people who live to our north, east and west.

The Commonwealth, too, has an opportunity by virtue of its strengths to carve out a new role for itself in the world...It is not an alliance or a trading area.... But it is a soft power network that represents the realities of our changing world and is underused. We intend to seize this opportunity in Perth.

As Australia changes, perceptions in the region will catch up, particularly if we improve our public and cultural diplomacy and our international broadcasting. We have to show that we believe projecting Australia in Asian countries is not a waste of time and money.
