At Goulburn Island, Roe was ambushed by natives and narrowly escaped with his life. Continuing west, "Mermaid" developed such a bad leak that King decided to careen her at a bay that was consequently named Careening Bay. Upon completion of repairs, the "Mermaid" was still found to be leaking, so the decision was taken to return to Sydney along the west and south coasts. Two rivers were discovered in York Sound and traced, one of them being named Roe River in honour of Roe's father.
