Henoch Raberaba started to paint in 1946 first under the guidance of his friend and tribal relative Albert Namatjira, then with another relative Edwin Pareroultja to work out his own style. Over a few weeks he evolved rapidly into a style of upward curving cliff bases beneath rocky cliff tops in a simplified lyrical style. He displayed his country flamboyantly and elegantly. He developed a system of harmonious patterning of curved parallel lines to emphasise the natural shapes of hills and trees. On occasion he invited the viewer into a space of apparent importance to him. He was painting seriously from 1946 to 1972. He was a founder of the Hermannsburg School and through his successful career he was an early role model to other Arrernte men.
According to the Palm Valley Land Claim Report of 13.8.1999 (3.7.7), the Raberaba family is quite small, but it is important traditionally, due to its close ties to the Ratara family. The large Renkeraka/Ratara group was the largest group to have prime spiritual responsibility for much of the Palm Valley land claim area. At the time of the Palm Valley Land Claim in the early 1990s the Raberaba family descendants asserted their ownership through their traditional ownership of the ‘Roulbmaulbma estate’ which overlapped the Palm Valley land claim area. The Roulbmaulbma area abuts the Ntaria Aboriginal Land Trust, extends eastward to Ellery Creek, to the Chewings Range in the north, claiming that their estate comes south as far as the junction of the Finke River and Ellery Creek at Rubula. Several Raberaba paintings portray the Ellery Creek area.
Henoch and his younger brother Herbert (1920-1980) did very well selling their paintings to the increasing tourist trade in Central Australia, as well as in the capital cities. Their locations were diverse. They were important painters and fully engaged in their art. Henoch was Western Arrernte, Subsection (Skin) Kngwarreye or Penangke. Henoch married an Arrernte woman, Regina (born 1917).
Henoch was a good friend of Albert Namatjira. Albert was convicted of leaving alcohol within reach of Henoch, thus leading to Albert’s conviction for supplying alcohol to Aborigines in 1958. Henoch Raberaba was the ‘tribal brother’ to whom Albert Namatjira, was convicted, as a non-Ward, for supplying alcohol. On an earlier occasion Henoch had been found at Hermannsburg too drunk to stand after a taxi trip with Albert.  In evidence at Albert’s trial in Alice Springs in August 1958, Henoch stated that although Henoch Raberaba was Albert’s tribal brother and not his blood brother, he was still obliged to share with him.
