John Henry Absalom OAM (11 November 1927[1] – 22 March 2019) was an Australian artist, author and adventurer.

He grew up along the Nullarbor Plain, west of Port Augusta, and from an early age developed a wide knowledge of the outback from Aboriginal Australians who existed in tribes at that time.

In 1973, Jack was invited to exhibit his paintings at an art show in Sydney together with fellow Broken Hill artist Eric Minchin.

The successful art show led to the formation of The Brushmen of the Bush – a group of five artists who exhibited for many years in Australia and all over the world raising money for charity.

[2] [3] In April 1997, he opened his new gallery in Broken Hill which showcased his oil paintings, prints, publications, DVDs and his extensive opal collection.
