1. Executive Summary Australia is the world’s driest inhabited continent, characterized by high climatic variability driven by ocean-atmosphere phenomena such as El Niño–Southern Oscillation (ENSO), the Indian Ocean Dipole (IOD), and the Southern Annular Mode (SAM). Its climate ranges from tropical monsoonal in the north to temperate in the south and arid desert in the interior. This paper provides a concise reference for understanding Australia’s climate zones, key influencing systems, seasonal patterns, and contemporary challenges including extreme heat, drought, bushfires, and flooding. 2. Major Climate Zones The Australian Bureau of Meteorology (BOM) classifies the continent into six primary climate zones:
