Australia Highseas

The Darumbal coast sea runs along central Queensland from Shoalwater Bay past the Fitzroy River mouth and the Keppel Bay islands toward Yeppoon. Inland, Darumbal country reaches across the plains and ranges around Rockhampton, Gracemere and the Boomer Range. Freshwater carried by the Fitzroy meets tidal channels, mangrove creeks and coral reefs, producing a boundary where river floods and open sea constantly reshape access.

Darumbal people used the coast and its islands as part of a wider territory of thirteen recognized bands with related dialects. Estuaries, shellfish beds, near-shore reefs and island landings offered food and routeways, while seasonal water and weather governed crossings. In May 1770 James Cook sailed through the bay and named it after Admiral Augustus Keppel. Matthew Flinders visited in 1802 aboard the Investigator, bringing the islands and mainland coast into European charts.

European survey did not create the coastal network. Darumbal routes linked fishing grounds, camps and inland country. By the 1830s, colonial expansion was approaching, but Rockhampton and the pastoral occupation that would transform the district lay beyond the period covered here. The bay remained a working indigenous seascape defined by tides, islands and river mouths.
