Already part of Hillsong Church since 2005, Fraser joined the Australian church's worship band—Hillsong Worship—where she participates under her married name: Brooke Ligertwood. The first album she was included on was the 2006 album "Mighty to Save", on which she co-wrote "None But Jesus" from "United We Stand", released in 2006. Her last live album with the band was the 2010 album "A Beautiful Exchange", after which Fraser left Hillsong Worship. The 2016 live album "Let There Be Light" marked Fraser's return and her first live recording with Hillsong Worship since her departure in 2010. She co-wrote and sang lead vocals on the song "What a Beautiful Name" for the 2016 live album. At the 2018 Grammy Awards, the group won the &lt;a href="Grammy%20Award%20for%20Best%20Contemporary%20Christian%20Music%20Performance/Song"&gt;Best Contemporary Christian Music Performance/Song&lt;/a&gt; award for "What a Beautiful Name". "Billboard" ranked the song as the top Christian Song of 2017 and third of the 2010s decade.
