…”When he arrived at Port Phillip Bay on 9 October, two days after the storeship Ocean, Collins was dismayed by the lack of timber and water, but he began unloading his convicts, settlers and stores at Sullivan Bay (near Sorrento), while Lieutenant Tuckey and George Prideaux Harris explored. Their reports were not encouraging, so he wrote to Governor Philip Gidley King suggesting removal of the settlement. King agreed, and Collins decided to move to the Derwent where Lieutenant John Bowen had already established a settlement at Risdon.

After reaching the Derwent, Collins landed at Risdon on 16 February, but he disapproved the place and soon chose and named Sullivan Cove as a better harbour and site for Hobart Town. “  http://adb.anu.edu.au/biography/collins-david-1912
