MacDonald along with fellow Tasmanian World War I veteran (and also the final surviving Australian Gallipoli digger) Alec Campbell were posthumously honoured on a commemorative plaque which was unveiled in front of two trees that had been planted in 1926. MacDonald's great-niece and Campbell's widow were present at the unveiling. MacDonald and Campbell had only met each other for the first time when they were both aged in their 100's at a Remembrance Day function in Hobart in 2001.
