Dalgety arrived at
Sydney in Australia on 2 June 1834 (at the age of 16) in the
Dryade and was an apprentice
clerk in a local merchandising business, T. C. Breillat & Co, a business that was just being set up by Thomas Chaplin Breillat. In December 1842 he moved to
Melbourne, which had only recently been established, and became manager of a new wool trading firm. In 1859, he returned to live permanently in England at
Lockerley Hall in
Hampshire and was appointed
High Sheriff of Hampshire for 1877. In 1884, with advancing age, the increasing demand for capital and competition from joint-stock companies and banks, Dalgety incorporated his private partnerships as a joint-stock company, called
Dalgety & Co, which was listed on the
London Stock Exchange. By that time it had operations in London,
Melbourne,
Geelong,
Launceston,
Dunedin,
Christchurch and
Sydney. ==Family==
