Both sugar and cream have been produced on Colonsay, a farm which was first established by Anders Jensen. Born in Aalborg, Denmark in 1848 Jensen had fought in the Second Schleswig War of 1864. He arrived in Queensland on 4 March 1871 on the ship "Reichstag" out of Hamburg, along with 328 other immigrants, mostly Danes and Germans. Of the 6400 Danes in Australia by 1891, about half lived in Queensland, and as skilled farmers they played an important role in the Australian dairy industry.
