Christmas Day, observed on the 25th of December, is a major annual celebration in Australia, much like the rest of the world. As Australia is in the southern hemisphere, Christmas Day falls in the summer season with weather conditions drastically contrasted with the snowy imagery commonly associated with the holiday. Despite the hot and sunny weather, Australians celebrate this holiday with equal enthusiasm embodying the spirit of unity, generosity, and love.

The traditions surrounding Christmas Day in Australia are a blend of inherited customs from the United Kingdom, United States, and unique Aussie adaptations. Many Australian families start the day by attending morning church services, followed by a lunchtime feast typically consisting of cold meats, seafood, and traditional Christmas desserts. One unconventional but iconic tradition includes beachside picnics and barbecues, especially in coastal locations, a scene quite distinct from the image of a white Christmas.

Gift-giving is an integral part of the Christmas Day celebration in Australia. Children eagerly await Santa Claus, known also as Father Christmas, to fill their stockings or place presents under the Christmas tree. Christmas decorations, including Christmas trees, lights, baubles, and nativity scenes, adorn homes, streets, and cities. Carols by Candlelight events are held nationwide where families come together in local parks to sing Christmas carols, rounding off the communal aspect of the celebration.
