Previously, all races of colour and ethnicity were placed under the one word: Indigenous. This not only created confusion but also disrespect to these two very distinct groups, Australian Aboriginal and Torres Strait Islander peoples.
It is imperative that the specific groups are named, Australian Aboriginal and Torres Strait Islander, and one does not place all groups under the word Indigenous.
As Aboriginal is a term used globally by and for indigenous peoples, within JCU it is important to distinguish Australia’s First Nations peoples as Australian Aboriginal people, not just Aboriginal.
Refrain from using non-Indigenous, rather use terms such as other Australians and the broader community.
It is appropriate to refer to Australian Aboriginals and Torres Strait Islanders as First Nations peoples.
It is derogatory to write or say ATSI, because they are two distinct groups.
You need to use the noun in the plural to reflect the two distinct cultural groups, for example, Australian Aboriginal and Torres Strait Islander peoples, cultures etc.
It must be remembered that there are many separate Aboriginal groups in Australia, despite some similarities in culture, history and physical appearances. Be conscious not to undermine the separate identities these groups have. Here is a link to a map on the ABC’s website, that gives an indication of just how many language groups and clans there are. Even so, there is debate about where the lines are drawn and no map can be said to be true.
