The memorial in St Martin's Church consists of three stained glass windows. The Northern Star on 23 May 1925 reported the newly arrived windows were designed by the artist Bustard and were completed by Mr McGuire in Messrs R. H. Exton's Studio in Brisbane. It explained the left window represents the "Good Shepherd", the right window represents "the Master in His Mother's Arms" and the central window depicts "the parish crest of St Martin's." The paper identified the donors as Mesdames F. Ward, C. Armbruster and Law, with the central window being dedicated to the memory of Frederick Charles Law killed in action and donated by his mother. The Mullumbimby Star on 4 June 1925 described the memorial windows and their installation in detail. Notes on veteran: Frederick Charles Law of Mullumbimby was killed in action as a trooper in the 5th Australian Light Horse Regiment on 26 November 1915 at Gallipoli, Dardanelles in Turkey.
