Poltpalingada Booboorowie (born c. 1830 – died 4 July 1901) was a prominent Aboriginal man of the Thooree clan of the Ngarrindjeri nation, who lived among the community of fringe dwellers in Adelaide, South Australia during the 1890s.

He was a well-known and popular figure among Adelaide residents, who knew him as Tommy Walker, and his antics and court appearances were reported upon regularly in the newspapers.

Photographs show him as a thick set man with bushy hair, a full white "flour bag" beard and grey felt top hat, wearing a ragged jacket or tail-coat, and barefooted.

Walker's begging was popular with the public as it resembled street theatre in which he would recount his most recent arrest, parodying the magistrate bringing down his sentence and imposing a fine.

As Aboriginals had free access to public gatherings, he frequented football and cricket matches at Adelaide Oval where he would entertain the crowd with dramatic recreations of his police court appearances, alternatively playing the part of both the magistrate and offender.

[citation needed] Booboorowie was the subject of several portraits by the Adelaide artist Oscar Friström,[2][3] one of which was bought by Sir Edwin Smith for the National Gallery of South Australia in 1894.

Walker was found to be in a "weak and feeble" condition from the effects of the cold weather and was admitted to the Adelaide Hospital but left on 28 June and returned to his wurlie in the parklands.

[5] In 1903 it was discovered that the coroner, Dr. William Ramsay Smith, had removed his skeleton before burial and sent it to the University of Edinburgh as an "anthropological specimen", making up the missing weight in the coffin with sand.
