Redlands couple celebrate a joyful diamond anniversary with family and friends.

The couple grew up in the Brisbane area, Barry in Coorparoo, and Edna in Moorooka.

They met when they were 18 after Mrs Holt's cousin brought Mr Holt over for a visit, and it was love at first sight.

The pair were married at St James Church in Coorparoo on June 10 1961 and moved to Victoria Point two years later where they remain today.

Their oldest daughter was born on their first wedding anniversary and they had three more children over the years.

Mr Holt worked as a commercial fisherman for 35 years, and he built his own trawler in his backyard and called it the Edna May after his wife. Mrs Holt did not work after she was married and stayed at home with their four children.

Mr Holt retired 20 years ago and the couple became avid campers, completing several trips travelling Australia in their caravan.

They still live in the Redlands and are surrounded by family with seven grandchildren and nine great grandchildren.

Daughter-in-law Nathalie Holt has known the couple for 29 years and said they were the most generous people she had ever met.

"They're very beautiful, kind people. They just want to help people, they would give you the shirts off their backs," Ms Holt said.

She said although she wasn't sure of the secret to their long marriage, they were always supporting each other.

"There's definitely some give and take, and I think that's one reason why they are so happy," Ms Holt said.

The family will celebrate with the happy couple with a lunch at the Cleveland RSL this weekend.
