OPAL meaning in Community ?

The One People of Australia League (often abbreviated OPAL) was an Australian Aboriginal political grouping in the 1960s and the 1970s. In contrast to the more radical and left-wing bodies advocating for indigenous sovereignty at the time, OPAL was for most of its existence overtly assimilationist, advocating for the integration of Aboriginal Australians into mainstream white culture. Its main focus was on welfare and housing and as it received monies from the Queensland government for its programs, the work of OPAL had both equal parts support and criticism for not being independent and operated by non-Indigenous organisers.
