Origins of Place names by ‘Earle’.
When the Gold seekers and prospectors tramped along the “Williams Track” there was an area beyond Launching Place known as ‘The Black Swamp’. Here a track branched off and followed the ‘Little Yarra”. At this junction of the ways arose the township of Yarra Junction.
 Warburton Ways, Earle Parkinson, 1984.
An integral part of the history was timber extraction, the cut logs pulled by bullocks and the sawn timber on bogies pulled by horses on hardwood rails. The Shire of Upper Yarra granted permission to constuct the Powelltown Tramway, a three foot gauge line, between 1913 and 1945 from Powelltown to Yarra Junction . The large central mill at Powelltown sent most of its timber on the tramway “the claim will be appreciated that more cut timber passed through Yarra Junction than any other place in the world except Seattle on the Pacific coast of the United States” 
The Upper Yarra shire first met at Millgrove in 1889, then at the old Mechanics Hall in Warburton before moving to Yarra Junction to the hall in Main Street. New council chambers were erected in in the 1930s. On 15 December 1994, the Shire was abolished and merged with the Shires of Lillydale,Healesville and most of Sherbrooke to form the Shire of Yarra Ranges
