They're A Weird Mob by Nino Culotta

A newly arrived Italian immigrant to postwar Sydney expects to join a newspaper run by his cousin, but when the plan collapses he takes work as a builder’s laborer. Through a series of comic misadventures, he grapples with Australian slang, pub culture, and rough-and-ready worksite etiquette, gradually earning acceptance and embracing mateship. The story affectionately satirizes both migrant naivety and local quirks, charting his assimilation, romance, and growing sense of belonging in a brash, booming city.
