Dr Younessi has published five books and is working on three new manuscripts and a screenplay.
His first book is a series of short stories called "From Threads to Fabric", which deals in a quasi-autobiographical way with the events in his childhood. He then wrote a book on the Australian vernacular called "How Australian Are You?" In this book Australian phraseology, history and cultural nuances are presented as a series of multiple choice questions and in a humorous manner. His third book was a novel called "Pan’s Penance." It is at times dark and deals with human relationships and social issues. It centres around the life of two friends from distinctly different backgrounds and their struggle to forge their identities. "Dead men Don’t Drive," is a series of short socio-political pieces with a satirical slant. His latest book, released November 2016, is an epic book of encyclopaedic proportions entitled: "Orders, Decorations, and Medals of the Empire of Iran - The Pahlavi Era." In this book he surveys the awards of the pre-revolutionary Iran in the context of heraldic and historic relevance of these to that particular epoch in the history of Iran. These books have enjoyed considerable success and have been the subject of newspaper articles and radio interviews.
