Entertainer Jeanne Little has died at the age of 82.
Little's daughter Katie posted on social media that her mother's death was a "huge shock".
"My mother has left the earthly plane," she posted on Facebook.
"This is a huge shock - but I'm so grateful.
"Love you all my friends."
Little's daughter created the Jeanne Little Alzheimer's Research Fund in 2011 after the Australian icon and television darling of more than 30 years was diagnosed with the disease in 2009.
Little made her TV debut in 1974, appearing on the high-rating daytime program The Mike Walsh Show, which was then airing on Network Ten.
Three years after making her first appearance on television, Little won the Gold Logie for Most Popular (Female) Australian entertainer and TV personality.
