The name Kirribilli is derived from an Aboriginal word Kiarabilli, which means 'good fishing spot'. The suburb initially formed in the vicinity of Jeffrey Street and was subsequently part of a grant to James Milson (1785-1872), after whom Milsons Point was named. The area was largely covered in native bush. As the decades passed, the land was cleared bit by bit and sub-divided, first for the construction of large family residences during the 1840s, secondly for the erection of Victorian terrace houses from the 1860s onwards, and finally for 20th-Century flats.
