During 1950, Gosse was part of an Australian armed forces recruiting campaign throughout South Australia, before collapsing from nervous strain at a rally in Renmark. In 1953 he was part of the contingent sent to the UK for the coronation of Queen Elizabeth II, and was awarded the Queen Elizabeth II Coronation Medal. In 1964, he travelled to the UK for a reunion and joined the Victoria Cross and George Cross Association. Gosse died of a coronary occlusion at Maslin Beach on 31 December 1964, and was cremated. The Victoria Cross recipient Brigadier Sir John George Smyth wrote that Gosse "always lived right on top of the world, as though every day was his last". He is commemorated on the Returned and Services League Walls at the Centennial Park Cemetery in Pasadena, South Australia.
