Delta Lea Goodrem (born 9 November 1984) is an Australian singer-songwriter and actress. Born and raised in Sydney, New South Wales, she enrolled in dancing, acting, singing and piano classes at a young age. She began her career as a child actress, starring in various television shows and rose to prominence in 2002 in the Australian soap opera Neighbours as Nina Tucker.
Venturing into the music industry, Goodrem signed to Sony Music at the age of 15 and released her multi-platinum album Innocent Eyes (2003), which topped the Australian Albums Chart and reached number two on the UK Albums Chart. It became one of the highest-selling albums in Australian history, with over 4 million copies sold worldwide and all five of its singles; "Born to Try", "Lost Without You", "Innocent Eyes", "Not Me, Not I", and "Predictable" reaching number one in Australia and the first three reaching the top ten in the UK. This gave her the record for becoming the first ever artist to have five number one singles from a debut album. As of the early 2010s, Goodrem holds the Australian record for the highest-selling album of the last decade (Innocent Eyes) and the most number one singles from a debut album.
Each of Goodrem's subsequent albums followed with similar commercial success on the ARIA Albums Chart. Her second studio album, Mistaken Identity (2004), was created while she was suffering from cancer (and several of its themes reflect this) and became her second consequent number one album. In 2007, Goodrem released Delta, her third number one album and in 2012, she released her fourth studio album Child of the Universe which reached number two. Goodrem has continued to have a string of top ten hits, including "Out of the Blue", "Mistaken Identity", "Together We Are One", "In This Life", "Believe Again", "Sitting on Top of the World", "Wish You Were Here" and "Heart Hypnotic". Goodrem has achieved eight number one singles and three number one albums in her home country. She has won three World Music Awards, ten ARIA Music Awards, a MTV Video Music Award and among several other awards. From 2012 to 2013, she served as a coach on The Voice Australia, and also appeared on The Voice Kids Australia in 2014. She returned to The Voice Australia in 2015.
