Scott Morrison's Father Has Died, Aged 84

John Morrison, the Prime Minister's father, has died.

Scott Morrison announced the news on social media on Thursday afternoon.

"Last night I received the sad news that my father John passed away quietly and peacefully. He was aged 84. He lived a great life and was much loved," the PM wrote on Facebook.

"He was a loving husband to my mum Marion for 57 years. 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."

Just hours earlier, Morrison had ended a Parliament House press conference by telling media "I have some family matters I have to attend to", but did not elaborate.

Morrison said his father lived "a life of love, faith, duty and service", detailing his service in the army, NSW Police, and as a local councillor and mayor.

"He served faithfully in his church throughout his entire life as an elder, youth worker and in aged care," the Prime Minister said.

"Dad had a deep and committed Christian faith, which is one of his numerous legacies in my life. Our family will miss him terribly, but we are extremely thankful for his great blessing in all of our lives."

"Love you Dad and well done good and faithful servant."

Former PM Julia Gillard -- who also lost her father while in office in 2012 -- sent her condolences to Morrison.

"Losing your dad is always hard, and even more so when you are serving as PM. My thoughts are with him and his family," she tweeted.
