[1] The history of the avenue was found amongst various newspaper articles on microfiche (dating from 1936) and historical publications held at the Tamworth Regional library.

It was also thought that the avenue should be of English oaks which, even though they are slow growing, they live to a great age, were beautiful trees and also symbolic of the link to England.

[1] Originally it was planned for the avenue to run from town along the Upper Nemingha Road (now the New England Highway), across the Two Mile Bridge over the Peel River, back along the Lower Nemingha Road (now King George V Memorial Avenue) and into town over the river via the Paradise Bridge.

The population of Tamworth in 1936 was 11,000 and the committee felt that the cost of 15 shillings per tree was small and that perhaps school children and other organisations in town would desire to be represented.

[1] By April 1936 99 trees had been promised by Tamworth residents, businesses and community groups including the CWA, RSL and the Light Horse Brigade.

This detour was called the "Round Drive" and the lower Nemingha Road was renamed King George V Memorial Avenue.

It was announced at that meeting that the opening and dedication of the avenue would occur during the Tamworth's Diamond Jubilee celebrations in October 1936.

In 1936 the Northern Daily Leader reported that the RSL and the Light Horse Brigade donated monies to purchase some of the trees for the avenue.

[1] In 1992 after years of public pressure Tamworth City Council agreed to establish an official register of significant trees.

[1][2] In August 2010 a development application (DA) was lodged with TRC to use King George V Avenue as the access route for a major subdivision of 500+ lots.

[1] In November 2011 another DA was lodged with council to trench through the root protection zone of the trees in order to place a wastewater pipeline.

It is also a representative of the last era when English Oak trees were commonly used for road side plantings, their use declining due to the difficulty in selecting areas where they would grow successfully.

[1] The surrounding land consists of flat alluvial flood plain used for a variety of agricultural purposes, including grain crops, lucerne and livestock grazing.

The growth of the English Oak is such that the foliage has interlaced overhead forming an arch as per the original intent of the avenue.

The avenue then used to extend 100 metres (330 ft) from Two Mile bridge to the Upper Nemingha Road until recently when the trees were removed in 2012 to make way for a carpark and entrance to a church.

[1] In 2009 the Australian Tree Consultants (ATC) were commissioned to assess the first half of the longer section of the avenue and found by them to be in varying conditions of health.

[1][6] Australian Tree Consultants reported that an ongoing program of care and replacement would ensure the avenue could be maintained in good condition for many years to come.

The oak trees have survived many floods and numerous droughts since their planting and the major cause of their ill health and loss over the years has been the poor pruning practices by the energy companies.

The "Round Drive" still exists but the final 0.5 kilometres (0.31 mi) section is no longer driveable due to the loss of the Two Mile bridge back over the river in the 1955 floods with this portion of the road subsequently being closed to traffic.

[1] Changes since 1936 have been:[1] The Avenue is of state heritage significance for its aesthetic values as the carefully planned planting has allowed the distinctive growth habit of oak trees to form a cathedral or tunnel like effect as the branches have grown and interlocked over the roadway, making the avenue aesthetically distinctive.
