It's been a swift boost to Australia's economic offers, Taylor Swift that is. As she wraps up her Australian tour tonight, some estimates put the financial gains from her seven concert stint at up to $1,000,000,000. A slice of that money's come from kiwi wallets; fans forced to travel to the lucky country, hosting the mega star. That means, spending on accomodation, food, taxis, ubers and merch, all money, that could arguably be spent here. Reporter Louise Ternouth caught up with these Taylor Swift fans just before they got on a plane headed for the Sydney concerts. Now in America, the swiftonomics are staggering with some number crunchers suggesting the tour could boost the economy by more than $9,500,000,000 NZD. After Australia, Swift heads to Singapore, who actively wooed the star months in advance and has confirmed it's Tourism Board paid a grant of an undisclosed amount, to secure the gigs. So has New Zealand made an economic Era, should we have paid for Swift to play here? Dr Angel Zhong of the Royal Melbourne Institute of Technology speaks to Lisa Owen.
