Mr Grey, who was also known as Youngat but more commonly as Pannican, worked with police in the Laverton-Leonora area from 1942-1962.

He was a Wongi man of the Ngaanyatjarra Tribe.

Born in 1920 in the lands east of Laverton, he started working as an approved police tracker at Laverton in 1942 with Constable Bert Anderson and continued as his tracker until 1948.

He also worked with several other officers in region until September 1962 and was recognised as a highly skilled tracker.

Mr Grey was a family man and an Elder treated with respect by other Wongi people.

He died in Kalgoorlie on April 2, 1967, and was buried in an unmarked grave at the Kalgoorlie-Boulder Cemetery.

Retired police superintendent and historian Robert Primrose proposed to formally acknowledge and honour Mr Grey’s memory.

The event was organised with the cooperation of Mr Grey’s daughter and relatives and is a gesture of reconciliation and acknowledgement of Aboriginal people’s contribution to policing in Western Australia.

The service was led by Commissioner Karl O’Callaghan at the Kalgoorlie-Boulder Cemetery on Wednesday morning.

The Minister for Police and Emergency Services John Kobelke also attended.
