Entrance to Avenue of Honour, 14 miles long, the Lucas Girls tribute to Ballarat soldiers Image of postcard published by Rose Stereographs from State Library of New South Wales retrieved from 9 March 2014

Avenues of Honour planted during and after World War I are an Australian innovation. The avenue at Ballarat was one of the first.

The young women employees of a Ballarat clothing firm, Lucas and Company, planted a tree for every soldier who left Ballarat to serve in the Great War. The avenue runs from the city westerly for 14 miles (over 20 kilometers). The first 505 trees were planted in June 1917.

3,900 trees altogether were planted. The Lucas girls also raised funds for an Arch of Victory at the beginning of the avenue.  The Arch was opened by the Prince of Wales on 2 June 1920.

Associated with the centenary of World War I, there is a project to preserve and restore the avenues across Australia: http://www.avenuesofhonour.org/ 
My husband’s grandfather Cecil Young and Cecil’s brother Jack have their names listed on a plaque with a small avenue of eucalypts planted in the grounds of the former school of Lower Homebush near Avoca in Victoria.

At Avoca nearby, an avenue was planted, but most of the trees have died . There presumably was a list of the men who were commemorated but I don’t know where that list is.
One of my favourite avenues is at Bacchus Marsh. It was planted in 1918 and is of Dutch elms. 281 trees were planted simultaneously on the afternoon of 10 August following the blowing of a bugle. The avenue extends for nearly two miles on the road towards Melbourne. In 2004 there were 312 trees and 48 vacant sites. A list of the names of the soldiers can be found at http://www.bacchusmarsh.avenueofhonour.org.au . On 28 May 2010, The Age reported on a plan to build a roundabout in the avenue and opposition to the proposal. For the time being the avenue is  intact. http://www.theage.com.au/national/a-matter-of-honour-20100527-whtb.html The avenue is listed on the Victorian heritage register http://vhd.heritage.vic.gov.au/#detail_places;4957
