The introduction of refrigerated railway cars made it viable to ship frozen meat, including frozen rabbit, to major cities and ports. Over the next three decades, rabbit trapping and freezing became a valuable industry. In Bungendore, NSW, a rabbit-freezing plant opened in 1906 and in the year ending July 31, 1909, handled more than 1.5 million rabbits. The plant employed 14 workers and over 250 trappers. The skins were also valued to make felt for the hat trade.
