ACT tourism authorities will try to use viral marketing in a new $1 million campaign to promote Canberra, offering 500 people a free holiday in return for spruiking the city through social media.

Australian Capital Tourism’s ”human brochure” campaign, which began yesterday, is trying to collect ”first-hand accounts of our nation’s capital”. It is looking for people who are active on social media, and will give them – and a friend or their family – a free weekend in Canberra.
