From 1889 Henry Saltau's son Marcus used the Warrnambool tramway offices as the base for his own produce and shipping business. With his associate James Jukes, Marcus Saltau incorporated his father's produce business and opened a Melbourne office. H Saltau & Sons were established in Melbourne as produce merchants around 1905. The firm chartered vessels to haul coal to Warrnambool and backload potatoes and general merchandise to Sydney and Newcastle, and an export trade in onions was set up with Canada and the United States of America. Marcus Saltau later became managing director of Saltau & Sons Pty Ltd from 1915 to 1945.
