Since 1984, federal electoral division boundaries in Australia have been determined at redistributions by a redistribution committee appointed by the Australian Electoral Commission. Redistributions occur for the boundaries of divisions in a particular state, and they occur every seven years, or sooner if a state's representation entitlement changes or when divisions of a state are malapportioned.[3]
History
The division was proclaimed at the redistribution of 13 July 1906, and was first contested at the 1906 election. The division was named after the Maribyrnong River, which runs through it. A safe Labor seat for most of the first half of the 20th century, it became a marginal Liberal seat for most of the 1950s and 1960s, in part due to the influence of the Democratic Labor Party. Labor retook the seat in 1969, and for most of the time since then, it has been a comfortably safe Labor seat.
