The former Caltex motor garage is a now rare building type developed prior to the introduction of single brand marketing, where roadside garages sold a variety of motor spirit brands to car owners. Prior to World War II, car ownership was low and as a result travel was seen as an adventure, made more palpable by the state of the roads throughout rural Queensland.
Motor garages were often associated with former wheelwright foundries and highway grocery stores where bowsers were located on the kerbside. Designed motor garages and service stations were relatively rare buildings, and this survivor of that period is a rarity in the context of Cairns and its environs. The building also has aesthetic significance at the local level as a motor garage designed in the Art Deco idiom.
