Black Friday in Australia is known for another reason, the Black Friday Bushfires
Taken from Wikipedia:
Black Friday history in Australia refers not to shopping at all but to the devastating Black Friday bushfires which occurred in Victoria 1938–39. Only recently, has it been promoted as a shopping day in Australia by in-store and online retailers.
In 2013, Apple extended its Black Friday deals to Australia. Purchasing online gave customers free shipping and free iTunes gift cards with every purchase. The deals were promoted on its website, reading “Official Apple Store—One day Apple shopping event Friday, November 29”. Australia Post’s ShopMate parcel-forwarding service allows Australian customers to purchase products with “Black Friday” deals from the US and get them shipped to Australia. In addition to this, numerous stores in the country run Black Friday promotions in-store and online throughout the country.
Black Friday Bushfires
Taken from Wikipedia:
The Black Friday bushfires of 13 January 1939, in Victoria, Australia, were part of the devastating 1938–1939 bushfire season in Australia, which saw bushfires burning for the whole summer, and ash falling as far away as New Zealand. It was calculated that three-quarters of the State of Victoria was directly or indirectly affected by the disaster, while other Australian states and the Australian Capital Territory were also badly hit by fires and extreme heat. As of 3 November 2011, the event was one of the worst[clarification needed] recorded bushfires in Australia, and the third most deadly.
