J. Hallett and Son, founded in 1904, was for most of the 20th century South Australia's most important brickmaking firm. Founded by Job H. Hallett in 1889, his son Thomas Hallett became a partner in 1904. There were several sites across Adelaide's western suburbs, with Halletts retaining their identity until the 1960s, when the company was absorbed by the Nubrik Hallett group (now Austral Bricks).
