In 2016, a DNA study confirmed that Aboriginal Australians are the oldest continuous culture on Earth, dating back 50,000 years. Scientists working on the study established that these "first real human explorers" originally migrated from the African continent, and were probably the first humans to cross an ocean. While Australia's First Peoples have suffered since the arrival of non-Aboriginals in the 17th century (and onwards), there’s still a vast quantity of sacred ancient sites which continue to serve Aboriginal and Torres Strait Islander communities today. From hand-printed rock art to modern-day cultural festivals, we take a look at the most incredible ones.
