Prime Minister Scott Morrison has announced his father, John, has died "quietly and peacefully" at the age of 84.
Mr Morrison said in a statement that he "received the sad news" on Wednesday night that his "much-loved" father, a former policeman and councillor, had died.
"He was a loving husband to my mum Marion for 57 years," Mr Morrison said.
"He was a wonderful father to me and my brother Alan. He loved Jen as a daughter and was a devoted grandfather to our girls."
John Morrison was a former officer with NSW Police and had served as a local councillor and mayor at Sydney's Waverley Council.
"He lived a great life and was much loved," Mr Morrison said.
Mr Morrison has repeatedly paid tribute to his father since becoming Prime Minister in 2018.
"My parents laid the foundation for my life," the Prime Minister said in his first speech in the Federal Parliament.
"Together with my brother, Alan, they demonstrated through their actions their Christian faith and the value they placed on public and community service. In our family, it has never been what you accumulate that matters, but what you contribute.
"I thank them for their sacrifice, love and, above all, their example."
Mr Morrison's mother, Marion, appeared with her son and his family during the election campaign.
His father was present on election night when Mr Morrison and the Coalition unexpectedly won the federal election.
"Dad had a deep and committed Christian faith, which is one of his numerous legacies in my life," Mr Morrison said on Thursday.
"Our family will miss him terribly, but we are extremely thankful for his great blessing in all of our lives."
