View of Eborac Island from Cape York

Eborac Island is located in the Adolphus Channel, a channel at the northeastern end of Cape York Peninsula and southeastern portion of the Torres Strait. The island is part of the Manar Group of the Torres Strait Islands. It is visible just across from Cape York, the northernmost point on the Australian continent. Its native name is Dyāra.[2]

Structure and display

Eborac Island Light was established in 1921. It was converted to solar power on 8 August 1990.[3]

The structure is a square concrete hut, 3 metres (9.8 ft) from the base to the platform. It is topped by a Chance Brothers 7 feet 11 inches (2.41 m) diameter lantern room. Both are painted white, and the total height is 6 metres (20 ft). A Helipad is nearby.[3]

The current light characteristic is two flashes, separated by two seconds, every 10 seconds, colored white, red or green depending on direction (Fl.(2)W.R.G. 10s). White, visible for 11 nautical miles (20 km; 13 mi), is shown at 267°30′-281°, 288°30′-000° and 135°-252°. Green, visible for 8 nautical miles (15 km; 9.2 mi), is shown at 252°30′-267°30′ and 000°-135°. Red, visible for 8 nautical miles (15 km; 9.2 mi), is shown at the small middle sector, 281°-288°30′.[4] The apparatus is a Chance Brothers 400 mm focal length Fresnel lens. The light source is a solar powered 12 Volt 35 Watt Halogen lamp and the intensity is 3,700 cd for the white light and 700 cd for the red and green ones.[3]

Site operation and visiting

The site and the tower are operated by the Australian Maritime Safety Authority. The island is accessible only by boat, and both the site and the tower are closed to the public. The lighthouse is, however, visible from the tip of Cape York, which can be reached by four wheel drive[1]
