From 2004 – 2012, Sarah Cockerell had been the principal researcher for TREENET on Avenues of Honour in Australia.  Much of this was voluntary or undertaken as a component of her PhD studies on the topic.

Through her initial research and a national survey, Sarah identified an preliminary total of 567 living war memorial sites:
2 in the ACT, 67 in NSW, 52 in Qld, 38 in SA, 69 in Tas, 312 in Vic and 27 in WA.

Her work has provided the basis upon which TREENET continues to build a comprehensive summary of the history and state of Australia’s living memorials.
