The group formed in 2012 out of Sydney, Australia, where they were located at Hillsong Church. Their members are worship leaders Aodhan King, Alexander Pappas, Tyler Douglass, Renee Sieff, Ben Tan, and Melodie Wagner. Hillsong United (launched in 1998), the original group, began when the members were all relatively young, since it was started as part of the youth ministry at Hillsong Church. As they started to mature, have families of their own, and take on adulthood, many people at the church felt there was a need for a new group that would aim its message at younger people with a stimulating new sound.^[1][2][3][4]
