The casting for Occupation was done internally by Luke Sparke and producers Carly Imrie and Carmel Imrie.
The three had extensive discussions about who they envisioned bringing to life the characters. They wanted to keep the project as universally representative as possible, within the casting of actors of various heritages and ages. It was an important step for Carly Imrie to connect with each talent agent personally, in order to discuss the roles and pitch the vision for the project. The producers felt fortunate to be able to cast the actors they did in the roles, as each had so much to work with and bring to the table.
