Jeremy Rockliff on Wednesday announced his dad Rick had passed away aged 79.

"Dad was a legend, a loyal, caring and proud dad, grandfather and loving husband of our gorgeous mum Gerry for over 55 years," Mr Rockliff said in a post on social media.

"We are so proud of all dad achieved across the fields of agriculture, local government, the arts and community service.

"Loved and remembered always."

Mr Rockliff has taken a short period of leave to mourn and be with family.

"Jeremy, together with his mother Gerry, and the extended Rockliff family are all in our thoughts and prayers at this time," Acting Premier Michael Ferguson said.

"(Rick) has been a tower of strength for the northwest community for many decades and was a much-loved husband, father, grandfather, farmer and community member.

"Rick shared with me on the day of Jeremy's swearing in as premier how proud he was of his son."

Rick attracted local fame for designing and making "Kenny" - a giant replica of a Kennebec potato used to promote the Rockliff family farm.

He was involved with opium poppy processing company Tasmanian Alkaloids for decades and had worked as deputy mayor of the Latrobe Council.

Rick was appointed a Member of the Order of Australia for his service to the community.
