Sentah Sonny Leo Unmeopa

Sentah Sonny Leo Unmeopa also known as Santa Unmeopa (12 January 1944 - 22 June 1996) was an Australian Torres Strait Islander man who was an Indigenous leader and activist for his people. He spent much of his life in Queensland where he was involved in activism throughout his life including as a leader in protests against Joh Bjelke-Petersen's government from the 1960s to the 1980s and other protests relating to land rights and self-determination for Australian First Nations people.

He was also later chairperson of ATSIC's South-East Queensland Indigenous Regional Council from 1993 until his death. One later arrest was on 29 April 1986, when he was involved in a sit-in at the Brisbane offices of the Aboriginal Development Commission and was charged with trespass; he was convicted but the charge was later overturned.

In the 1980s he was also, alongside footballer Joe Kilroy, one of the only Indigenous members of the Black Uhlans Motorcycle Club. However, in 1996, the office, and therefore Unmeopa, was cleared of any wrongdoing.
