In 2006, Youngquest posed nude for the "Naked Rugby League Calendar 2007-08", stirring controversy after his revealing pose - in which one hand is placed partially over his genitalia. The NRL reacted by distancing itself from the project, stating that they do not endorse nor authorise the calendar. The sales of the calendar helped to raise funds for the National Breast Cancer Foundation. Youngquest has also worked as a professional model. He is hired by agencies Ford Models and DT Model Management, and has done advertising campaign for designer fragrances Paco Rabanne.
