Teams have started arriving in Australia for the Asian Football Confederation Asian Cup, which is set to deliver a boost to the economy of $1 million a day over three weeks. The multi-city tournament kicks off on January 9 when Australia plays Kuwait in Melbourne. Sixteen teams will play 31 matches in Sydney, Melbourne, Brisbane, Newcastle and Canberra. The 23-day event could add $23 million to gross domestic product, and as much as a 15% jump in tourist numbers in the month following the tournament. As well as boosting international and domestic tourism numbers, the cup will showcase Australia to a potential television audience of 2.5 billion. Asia is already Australia's fastest growing and most valuable international inbound tourism region.
