The Shire of Diamond Valley was a local government area about 20 kilometres (12 mi) northeast of Melbourne, the state capital of Victoria, Australia. The shire covered an area of 74.38 square kilometres (28.72 sq mi), and existed from 1964 until 1994.


The name relates to the lowlands to the west of Diamond Creek, a tributary of the Yarra River, which flows through nearby Eltham.

The Diamond Valley can be defined in geographical terms as the area bounded by the Plenty River, the Yarra, the Christmas Hills ridge to the east and the Great Dividing Range to the north.[2]

Land in the area was first incorporated as part of the Heidelberg Road District on 12 October 1860, which became a shire on 27 March 1864 and was proclaimed as the City of Heidelberg on 11 April 1934.[3] On 30 September 1964, the North Ward of the City of Heidelberg was severed, and incorporated as the Shire of Diamond Valley.[3]

In 1863 the Diamond Reef was discovered by Thomas Wright Soady on Dr John Blakemore Phipps property which stretched from Reynold's Road to the Diamond Creek.[2]

On 15 December 1994, the Shire of Diamond Valley was abolished; areas south of the Metropolitan Ring Road and the Greensborough Highway were transferred to the newly created City of Banyule, while areas north were merged with most of the Shire of Eltham and parts of the City of Whittlesea, into the newly created Shire of Nillumbik. A small area in the shire's southwest, north of La Trobe University, including Gresswell Forest Nature Reserve, was transferred to the City of Darebin.[4]

Council met at the Diamond Valley Civic Centre, in Civic Circuit, Greensborough. The facility is still used by the Shire of Nillumbik.


The Shire of Diamond Valley was divided into four ridings, each of which elected three councillors:

  • South West Riding
  • South East Riding
  • Centre Riding
  • North Riding
