Whilst still in high school she formed a duo with Jack Gray and released a CD of indie folk tunes, produced by Australian country star, Bill Chambers, in 2014. The duo subsequently split and Tia forged ahead with her solo career.

In 2015, at the age of 16, Gostelow wrote "State of Art" which was released in February 2016 as her debut single. "State Of Art" received airplay on national youth broadcaster Triple J, won the station's 2016 Indigenous Initiative and placed top 5 in Triple J Unearthed High in 2016.

She has released three albums since then.
