At the core of any economic system is the transfer of goods and availability of labour. Our ancestors played their part in developing colonial Australia where great distances and difficult terrain limited apparent boundless opportunities. Duthie, Whitfield and Montgomery ancestors sailed and piloted ships which carried goods to Australia and in the coastal trade. Some constructed vessels in Newcastle and Port Melbourne and several ran vehicular ferries on major rivers. In the vital railway industry, Childs, Rumble, Adam, Boyd, Adams, Whitfield, Campbell and Scrivener men laid the iron rails, drove the locomotives, were engineers in railway workshops, carriage builders, guards, signallers, station masters and worked in the Enfield and Darling Harbour goods yards as well as locomotive construction (such as 3801) at Everleigh in Sydney. The McCallums built the drays and other horse drawn vehicles that connected people with the railways and ports. Campbells and McAllisters were carriers in the horse drawn transport era in Queensland and northern NSW. Men of the McCallum, Scrivener and Campbell families, shod horses and manufactured goods and vital components for vehicles. All contributed to the national as well as their local economies.
