Taylor Swift fan MJ De La Rue estimates she has spent at least $10,000 on the singer's merchandise and albums over decades as a committed Swiftie.
For the Eras Tour alone, the 30-year-old has spent more than $1000 for tickets to three concerts, and plans to wear a different outfit each night.
Thanks to fans like De La Rue, the Victorian and NSW economies can boast of raking in dollars, with the tour providing an economic boost for both states.
