Taylor Swift 's RED Tour is off to a huge start in Australia. More than 40,900 fans packed into Sydney's Allianz Stadium on Wednesday to see her concert, making Taylor the first woman in history to sell out that venue. Taylor is also the first solo female act to headline stadiums in Australia in 20 years. Her trek continues through a December 14 date in Melbourne.
