Australian Aboriginal culture includes a number of practices and ceremonies centered on a belief in the Dreamtime. Reverence for the land and oral traditions are emphasized. Language groupings and tribal divisions exhibit a range of individual cultures. Australian Aboriginal art has existed for thousands of years and ranges from ancient rock art to modern watercolor landscapes. Aboriginal music has developed a number of unique instruments. Contemporary Australian aboriginal music is predominantly of the country music genres. Indigenous Australians did not develop a system of writing.
Indigenous Australians' oral tradition and spiritual values are based upon reverence for the land and a belief in the Dreamtime. The Dreaming is considered to be both the ancient time of creation and the present day reality of Dreaming. There are many different groups, each with their own individual culture, belief structure and language.
These cultures often overlapped, and evolved over time. The Rainbow Serpent is a major ancestral being for many Aboriginal people across Australia. Baiame or Bunjil are regarded as the primary creator-spirits in South-East Australia. Dingo Dreaming is a significant ancestor in the interior regions of Bandiyan as Dingo formed the songlines that cross the continent from north to south and east to west. The Yowie and Bunyip are other ancestral beings.
Traditional healers (known as Ngangkari in the Western desert areas of Central Australia) were highly respected men and women who not only acted as healers or doctors, but were also generally custodians of important Dreamtime stories.
In principle, census information could identify how widespread are traditional Aboriginal beliefs compared to other belief systems such as Christianity; however the official census in Australia does not include traditional Aboriginal beliefs as a religion. For example, the 2001 census form listed Catholic, Anglican (Church of England), Uniting Church, Presbyterian, Lutheran, Islam, Greek Orthodox, Baptist, "No religion", "Other - please specify", and Buddhism. The following census information is therefore likely to over-represent the listed beliefs compared to traditional Aboriginal beliefs.
