Mrs Grieves reached triple figures on Saturday January 4 and celebrated her centurion lap around the sun with 30 close friends and family.

The celebration involved a private dinner party held at the Mount Isa Irish Club on her birthday.

The significance of turning 100 was acknowledged in letters from dignitaries such as state member for Traeger Robbie Katter, federal member for Kennedy Bob Katter, Premier of Queensland Annastacia Palaszczuk, Prime Minister Scott Morrison, Governor-General David Hurley and the Queen.

Tony McGrady said during the dinner Mrs Grieves received a telephone call from Father Mick Lowcock and Premier Palaszczuk congratulating her.

"They chatted about the old days in Mount Isa and in particular her work for OPAL (One People of Australia League)," Mr McGrady said.

Mr McGrady said the music throughout the evening was old wartime hits of Vera Lynn.

"Connie used to serve in the forces and remembered the songs word for word," Mr McGrady said.

Mrs Grieves departed England in 1950 to move to Mount Isa after her late husband Arthur Grieves was impressed with the town.

Mrs Grieves also made a name for herself in the region working as a journalist with the old Mount Isa Mail.
