According to the International Hydrographic Organization, the line separating the Bass Strait from the Great Australian Bight runs through King Island, so Christmas Island lies in the Great Australian Bight.
Christmas Island is not to be confused with Little Christmas Island on Tasmania's east coast or the Australian external territory Christmas Island in the Indian Ocean.
