Aranda's Migrations and Diaspora.

          In the 1950's the Aranda tribe was moved out of Santa Teresa to Arltunga because Arltunga had way more opportunities and a better lifestyle for the tribe. However, a war started to brew in because Arltunga was found to have a lot of gold. It became war, the Aranda people were struggling with the outsiders coming in and mining all over their land. These outsiders were not just ruining their land, but scaring their food away. 

          This was not the only problem the Arrente people had to deal with, over the years many more tourists were coming from around the world and their main site seeing area was the Urulu. Thanks to National Parks being built and the other Aboriginal tribes for working together to get the National Park to help keep Ayer's Rock safe from harm  and as natural as can be. The great part is the Aboriginal people worked hard together to keep their sacred lands safe and they did. Now with a little help from the friends at the park they work together and keep everyone happy.
