Former prime minister Bob Hawke says he remembers his ex-wife Hazel with deep affection.
Mrs Hawke died on Thursday aged 83, after a battle with dementia.
"I remember Hazel with deep affection and gratitude," Mr Hawke said in a statement on Friday.
"She was more than a wife and mother, being father as well during my frequent absences as I pursued an industrial then political career."
Hazel did an outstanding job as Australia's first lady during his time in power from 1983 to 1991, he said.
"She was a constant support, particularly through some very difficult times.
"Our three children, Susan, Stephen and Rosslyn, adored their mother as did our six grandchildren, and my thoughts are very much with them at this time."
Mr and Mrs Hawke divorced in 1995.
