The Romano WE84 is an Australian designed and built, mid-engined closed top racing car built to CAMS Group A Sports Car specifications. The car began its life as the Kaditcha K583 when it first appeared in the 1983 Australian Sports Car Championship and was built by the Queensland based Kaditcha owner and former McLaren engineer Barry Lock after he was approached by Brisbane accountant, property developer, timber mill owner and former speedway racer Bap Romano in 1981 with the idea of building a Le Mans type coupe. When the car first appeared in 1983, it was the first closed top Sports Car seen in Australia and looked like an FIA Group C Sports Car rather than the open cockpit Can-Am style cars of previous years. This led to the false belief that it was built to the Group C regulations

The 1984 Sandown 1000 was an endurance motor race staged at the Sandown Raceway in Victoria, Australia on 2 December 1984.
