Is a non perennial creek rising south east of Mount Airly. It flows generally south, south west for about 3km into Reedy Creek. First shown on the map Parish of Coco, County of Roxburgh, 4th edition, 1918. To date, no research has unearthed the origin of who Malcolm was. Perhaps with Scottish names in this area, such as Airly and McLeans, it may have been named after King Malcolm of Scotland.
