Plaque about the Swan River Colony on the Rockingham Waterfront Pioneer Rotary Walk in Rockingham, Western Australia. It reads, "The Swan River Colony officially came into existence in June 1829. "H.M.S. Sulphur" negotiated the sandbanks and joined the two vessels in the lee of Garden Island. A small settlement was being established on the island, where Captain, now Lt Governor Stirling, had taken up residence, erecting his house on Cliff Head."
