The sign was erected in the reserve in November 2015. Leo O'Brien was a long time Sunbury resident and the son of Terence O'Brien, who farmed in the district. The reserve is on a section of land that Leo owned, which fronted Barkly Street to the west and Jackson Street to the east. As Sunbury developed the higher section of the property was subdivided for housing and today Terence Street is in that subdivision. The Leo O'Brien Reserve area could not be developed for housing because that land is part of the former main drain, which was a natural waterway that flowed through a part of Sunbury an entered Jacksons Creek at the end of Brook Street. Today the open drain is covered over. Terrence O'Brien served as Shire President on Shire of Bulla Council during the first two decades of the twentieth century and was also a member of the Sunbury Waterworks Trust from 1913 - 1914.A coloured photograph of sign placed at the entrance of a small open space. Tables and chairs have been set out for refreshments in the reserve.leo o'brien, leo o'brien reserve, terence o'brien
