Ronald Peter Tandberg (31 December 1943[1] – 8 January 2018) was an Australian illustrator and political cartoonist who contributed to The Age newspaper in Melbourne, Australia from 1972.

[3] Tandberg was born in Melbourne to working-class parents[4] and raised in a small house at the suburb of Pascoe Vale South.

Editor Graham Perkin declined, but offered him a job as a political cartoonist, which he reluctantly accepted in 1972, thus beginning a 45-year career with the newspaper.

[7] Tandberg illustrated an HIV/AIDS prevention poster campaign for the National AIDS Education Council with the tag line "If it's not on, it's not on" (referring to a condom), which was widely distributed in Australia in the early 1990s.

[8] Tandberg died of oesophageal cancer at St John of God Hospital, in Geelong, Victoria, surrounded by his family, in the afternoon of 8 January 2018, at the age of 74.
