The Maitland Brown Memorial was sculpted by Pietro Giacomo Porcelli and was unveiled in February 1913. The 9-12 ft. granite and bronze memorial was the subject of controversy. One plaque depicted aborigines in shackles, several other plaques commemorated Police Inspector J.K. Panter, Police Constable W.H. Goldwyer and James R. Harding, who were murdered in 1894. The controversy with the work lies with the biased textual description of the murder of the three men. Aboriginal communities protested the unfair inscription on the memorial and the memorial’s failure to recognize the Aborigines murdered in La Grange Massacre (La Grange Expedition), in which Maitland Brown made a retributive attack on an Aborigine village on April 6, 1865.

In 1990 the head of the Maitland Brown sculpture was chopped off. A replacement bust was made, and for unknown reasons the original head was returned in 1993. In 1994 a new plaque was added that commemorated the Aboriginal people who were killed at La Grange. In 1995 one of the plaques was stolen and a new one added the following year.
