Some of the hottest temperatures included the outback South Australian town of Marree, where the mercury nudged 49.8C. Marree was the hottest spot on the planet for a day, according to online world temperatures site El Dorado Weather. Australia also claimed all of the top 15 hottest spots in the world over the 24 hours to 8am on Thursday. Senior meteorologist Dean Narramore said the blistering heat had broken dozens of temperature records across South Australia, NSW and Victoria over the course of a week.
