In addition to being an acclaimed author, Mr. Corris was an academic, journalist and former literary editor of The National Times.

"He was a really positive, happy person, unlike most of the authors, he was humble, he was not full of ego," his friend Kathy Gollan told ABC.

Mr. Corris was diagnosed with type one diabetes at the age of 16 and has had problems with the disease since then.

He lost his sight in the last year, which forced him to stop writing.

"My sight, which has been poor for a long time, suddenly decreased and it was too difficult, too stressful, too painful, really, to write more," he said.

"I can still move and do most things … but things like writing and reading, etc., have become too difficult."

The prolific crime writer leaves behind his wife, author Jean Bedford, his three daughters and seven grandchildren.
