Martin Dibble is a fictional character from the Australian television soap opera Home and Away, played by Craig Thomson. He made his first appearance during the episode broadcast on 17 January 1988, during the show's pilot episode. Martin is characterised as an idle and concoctor of schemes that are always unsuccessful. Thomson has described him numerous times as a "yobbo" or a "yob". Writers often used Martin for comic relief in between the show's more serious stories. They also created an on-screen partnership between him and Lance Smart. Together they were the show's "larrikins" with over-the-top personalities.

Lance Smart is a fictional character from the Australian Channel Seven soap opera Home and Away, played by Peter Vroom. Vroom appeared from the pilot episode as one of the serial's original characters. Lance is characterised a "slow witted" larrikin and those around him see him as a "joke". Lance forms an on-screen partnership with Martin Dibble and their characters were subsequently used as the serial's comedy characters. Both Vroom and Thomson said that their characters did not provide a realistic representation of young people as the production team often censored their dialogue. Lance also has an over-protective mother Colleen Smart with whom he had to contend with. His main romantic relationship is with Marilyn Chambers and the pair became engaged. Their romance was short-lived as Lance decided against marrying her. Lance and Martin were named as the "thickest characters ever to grace soapland" in the Daily Record.
