Halloween is an annual observance every 31 October in Australia. It is not an official holiday, but it is an increasingly popular festive event thanks to marketers. Though it has modern roots in American popular culture, Halloween’s true origins are in centuries old Celtic and Christian traditions.
Australia is still in the process of adopting Halloween as its own holiday. As it stands, it’s considered an American importation, and it is only partly and half-heartedly celebrated by many. Nonetheless, Halloween has a true and growing presence thanks partly to marketers desperate for an extra reason to make sales.
Costumes still focus on blood and gore and scary beings and are almost entirely restricted to kids. That’s different than America, where you dress up to be “anything you want to be” and adults and kids alike participate.
There isn’t much Halloween food in Australia yet. And trick-or-treating has only partial participation. That’s why Australians have started leaving an orange balloon floating by their front door or similar decoration if they have candy available – so trick-or-treaters don’t knock in vain (or disturb someone who has no time for this “American import”).
