Gerald Carr was born in Bendigo Victoria and studied art at the Bendigo Institute of Technology. He worked in Sydney for Walter Grainger Publications lettering translations for Australian Disney comics, before moving to Melbourne in 1967 to work in advertising agency and printing.

Carr's first comic Brigette was published in Go-Set (October 1968 to May 1969) before becoming a newspaper strip from 5 July 1969 in the Sunday Independent (Perth) and Sunday Mail (Brisbane). Because of its mature themes it was dropped within a few months, but picked up by Newsday (Melbourne) for five months from October 1969. In 2002, some strips were reprinted in Italy in Eroine Di China, published by Fumetto.

Carr created the Barbarella-style strip 'Fabula' for Broadside (1969), self-published the one-shot fanzine Wart's Epic (1970), and took over drawing 'Devil Doone' for KG Murray (1971). Material developed for his first limited-distribution self-published comic in 1974 lager became Vampire! (1975), responding to the black and white horror boom. In 1980 Carr published Brain Master and Vixen, Fire-Fang and Shock Raider, while working on advertising and book illustrations.

Carr's war story 'The Dirty Digger' was published in Australian War Stories by Southern Aurora (1994) and republished as a one-shot in 1996. He launched his Meteor Comics imprint in 1995, publishing a second series of Vampire!, which reprinted his earlier 'Fire Fang' stores, and a new series of Vixen (originally created for Wart's Epic), which included 1950s Australian comic characters Captain Atom (renamed 'Atomic Warrior') and The Panther, licenced from their creators Arthur Mather and Paul Wheelahan. Since 1995, Carr's has published comics online and sells merchandise featuring his characters.

In 2016 he won The Jim Russell Award for significant contribution to Australian cartooning from the Australian Cartoonists' Association. Carr was a pioneer of Australian comics, reflecting the changes and challenges since the 1970s.
