Assistant Surgeon Thomas Jamison commented “from the number of people that were then on this Island, and many of those that were landed from the Sirius and Supply being sickly, in a consultation held by you (King), Lieutenant-Governor Ross, and Mr. Considen, assistant surgeon I was requested to stay to assist that gentleman, which I complied with, and continued until the return of Captain Hunter (our present Governor) in the Supply to Port Jackson (February 1791)”
