The Yorke Peninsula's principal port, Wallaroo is also a popular tourist resort, attracting visitors to its safe beaches and excellent fishing. Snapper is the sought-after catch during winter and spring, however many other fish species are caught from the jetty and rocks. A concrete all-weather boat ramp at Office Beach caters for those who wish to try their luck in deeper water. For those who prefer indoor activities, the Wallaroo Heritage and Nautical Museum provides a maritime experience on dry land.
Copper found in the area in the late 1850's led to the settlement of Wallaroo and its development as a port for shipping the ore mined throughout the Copper Triangle region at the top of the peninsula.
The origin of the name Wallaroo is actually a corruption of the Aboriginal term wadla-waru meaning 'wallaby urine'. The Walla Waroo run was taken up by Walter Watson Hughes. It is said that the name was shortened because it was too long to stencil on wool bales.
