The original Archer Point
Lighthouse was very similar to the structures on Geese Island, Flat Top, Bay
Rock and
Grassy Hill - a timber framed tower sheafed in rolled galvanised iron sheeting.
The
lighthouse is prominently situated on a
grassy hill.
Archer Point
lighthouse, with the now disused Rocky Islet
lighthouse once formed the lead between the Hope Islands and the mainland to the south, and to the north between the mainland and the coral reefs to the eastward.
At night, the white sector of the light indicates the clear passage and the red and green sectors indicates the ship is outside the channel.
With the building of the new light in 1979 it was converted to electricity.
