In the 1880s and 1890s Wragge set up an extensive network of weather stations around Queensland, and developed a series of storm signals to be used upon telegraphed instructions from Brisbane to Cape Moreton, Double Island Point, Sandy Cape, Bustard Head, Cape Capricorn, Flat Top Island, Cape Bowling Green, Cape Cleveland, Cooktown, Thursday Island and Karumba. He also set up an international service with New Caledonia, by which he received data on the newly laid cable from Nouméa. Between 1888 and 1893, Wragge trained Inigo Owen Jones who became a renowned long-range weather forecaster.
