These days, Aborigines dress like Europeans. Remember that, for the most part, they are fully functional members of society, adhering to European customs. When the first Europeans came, the Aborigines liked the colours and feel of their clothes, and were happy to adopt some of the European clothing cutsoms.

Indigenous people of the southern states used animal skins to keep warm in winter.
