Pence, his wife Karen, and their two adult daughters, Charlotte and Audrey, saw some of the sights of Sydney, investing time in soft diplomacy on the last leg of a 10-day Asia tour that has been rich with symbolism about shoring up American economic ties and security cooperation. Karen Pence - who earlier charmed a meet-and-greet with embassy families with her pronunciation of "G'day" - held out a handful of chicory to Widji, an emu who boldly pecked at the bunch.

Australian animals have long been dispatched internationally as a form of diplomacy. In the past two years however, it has been koalas, rather than the platypi, who have shot to international notice as key Australian contenders in political power plays. 

Diplomacy may be an expensive business but the $400,000 cost racked up by the Australian government for foreign diplomats to cuddle koalas and other marsupials is too hefty, the opposition has said.“International diplomacy has a role and soft power is very important, but you’ve to get the balance right. Sometimes this government goes over the top because they don’t care about the money.” 

In historical efforts at cultivating soft power –​ Australia's public image overseas –​ we've leaned pretty heavily on the wildlife [...] Koalas. Beaches. Barbecues. Where's the messaging that Australia is a successful, multicultural, safe, educated, vibrant democracy; the 12th biggest economy in the world; the home of the world's oldest living culture; of Cate Blanchett and Hugh Jackman but also Atlassian and Canva; of the inventors of WiFi, the black box and Gardasil? 

Diplomats with these koalafications don't come cheap. Foreign Minister Julie Bishop could barely contain her glee when she was filmed with the furry foursome of Paddle, Chan, Pelita and Idalia at the launch of Singapore Zoo's new koala exhibit last week. But Australian taxpayers might not be so happy to learn that the diplomatic donation – made to mark 50 years of Australia-Singapore relations – cost them $133,100.

Four female koalas have just made their debut in front of an adoring public at Singapore Zoo – the latest in a long line of animals used for diplomatic purposes. [...] As Australian Foreign Minister Julie Bishop’s media release says, the koalas' visit will “further build on our long-standing constructive relationship”.

The Australian government has an elaborate campaign, including a 600-page bureaucratic handbook, to build its international image using koalas.

Australia has begun formalising the use of koalas as a "soft power" diplomatic strategy, with a 600-page manual having been drawn-up by the foreign affairs department and the marsupials increasingly being given to regional allies.
