 set on sheds on the wharves. A signal staff was erected on Grassy Hill in 1874 to announce incoming ships, and a cottage was constructed for the signal staff operator in 1878-79. By 1882 a temporary light was set on the hill. In 1883 and 1884, George Poynter Heath, Portmaster of Queensland and Chairman of the Queensland Marine Board at that time, made two reports to the parliament, recommending that the temporary light be replaced with a permanent building and a proper apparatus.

Grassy Hill Light was finally constructed in 1886. It was the second in a group of eight lighthouses in Queensland made of hardwood

. The light keeper resided in the existing cottage and also maintained a signal staff.
In 1900 a new cottage was constructed for the light keeper. In 1912 a report recommended that the lighthouse be automated, leaving the keeper only the signal duties. However, this recommendation was not to be taken for some time. In 1913 a wireless station was installed nearby and in 1915 the light, alone with all other coastal lights, was transferred to the control of the Commonwealth government. It was only in 1927 the lighthouse was finally automated, the light source was changed to an acetylene gas burner, and the station was demanned. The keeper's house and signal staff were destroyed about that time.

Structure

The lighthouse is conical in form, about 6 metres (19.7 ft) high, constructed of timber clad with corrugated iron sheets, on a concrete base. It is about 3 metres (9.8 ft) diameter at the base. Small rectangular windows are set about mid height on the south and east sides. Entrance is through a small entry on the western side, with timber-framing, convex corrugated iron roof, and timber double doors.
The tower is topped by a balcony supported on timber brackets which has a lightweight balustrade. The cylindrical lantern sits above, capped with a hemispherical dome. Access to the light is via a timber stair. The tower is painted white, with the dome and the concrete base painted red.

Display

The light characteristic shown is two white flashes every six seconds (Fl.(2)W. 6s). It is visible only on a limited sector, 192°-315°, and obscured elsewhere.

Operation and access

The site is managed by the Cook Shire Council. It is accessible by road and parking is also provided. The tower is, however, closed to the public.
