Jaimi, 33, passed away peacefully on Monday morning at Sunshine Coast University Hospital following a long battle with illness.

"It goes without saying that this is a very difficult time for family and friends and we trust we will all be allowed to grieve in privacy," the Curry-Kenny family said in a statement.

"Our hearts are broken and the pain is immense but we must move forward cherishing every wonderful moment we got to share with our treasured first child."

In an Instagram post, Curry said her daughter's death didn't feel "right or real."

"I will miss you when the clouds are dark and stormy and when the rainbow appears. I will miss you when I close my eyes. I will miss you when I open my eyes," the champion swimmer posted.

The grieving parents thanked Sunshine Coast hospital staff for giving them extra time to spend with their daughter.

"Jaimi will forever be remembered as a caring, bright and loving soul who always put others before herself," the family said.

Known as Queensland's sporting royalty, the pair married in 1986 and had three children before divorcing in 2017.

Curry competed in the Olympic Games in Moscow, Los Angeles and Barcelona.

Iron man champion and canoeist Kenny won an Olympic bronze medal in the K-2 1000m event with Barry Kelly at Los Angeles in 1984.
