Linda down at the Maffra Historical Society blog has put up some very beautiful examples of the mosaic style of Honour Roll to be found at the Maffra Library. These memorials Linda believes are by the Melbourne company Brooks, Robinson & Co which advertised in Anglican newsletters. It is possible that the Roll of Honour at St Thomas' Anglican Church in Moonee Ponds is this sort of thing - I do remember it having tiles with names inscribed but can't quite recall the rest.
I have created a commemorative online database of the WW1 volunteers of Essendon and Flemington in Victoria, with a blog to support the website: see link below.
I have other websites and blogs which follow other interests.
