Mobilong is a suburb of Murray Bridge in South Australia, on the west bank of the Murray River.[1] Its boundaries were formalised in March 2000 to cover a portion of land adjacently north of the Murray Bridge city centre and including the Mobilong Swamp and Murray Bridge Irrigation Area.[1]
Mobilong was the original name for the early settlement of Murray Bridge itself. The present-day locality, however, was specifically named after Mobilong Swamp in 2000.[1] According to South Australian historian Geoffrey Manning, the word Mobilong is a corruption of the Aboriginal term mupulawangk, meaning "soft reed place" as "reeds along the [Murray] river bank were used in the making of coiled baskets."[2] The word appears to have first been used officially in the vicinity to name the cadastral division, the Hundred of Mobilong, in 1860.[3]
Despite its name, the Mobilong Prison is not in the locality of Mobilong, but in the northwestern corner of the locality of Murray Bridge, adjoining Rocky Gully.
