Raine Island Beacon is a maritime navigation aid located on Raine Island, a coral cay situated on the outer edge of the Great Barrier Reef, approximately 1,555 km (966 mi) north‑north‑west of Brisbane, Queensland, Australia. The beacon forms part of the Raine Island Light complex, which was established to guide vessels navigating the heavily trafficked shipping routes through the Coral Sea and to support the safe approach to the island’s historic seabird nesting grounds and the Australian Maritime Safety Authority’s (AMSA) facilities.
Location and Physical Description
- Geographic coordinates: 11°34′S 149°48′E.
- Structure: The beacon consists of a cylindrical concrete tower, 10 m (33 ft) in height, surmounted by a lantern room that houses an automated light apparatus. The tower is painted white with a red band near the base for daytime visibility.
- Light characteristic: The beacon emits a flashing white light with a nominal range of 15 nautical miles (28 km), operating on a 30‑second period (2 seconds on, 28 seconds off). The light source is a solar‑powered LED system, automated and monitored remotely by AMSA.
Historical Development
- Initial establishment: The original navigation aid on Raine Island was a timber pile lighthouse first lit on 1 April 1883, constructed to replace a provisional beacon that had been in use since the 1860s.
- Upgrades: The timber structure was replaced in 1937 by a concrete tower to improve durability against the harsh marine environment. In 1990, the light was automated, and the keeper’s accommodation was de‑staffed. A solar power conversion was completed in 2006, eliminating the need for a diesel generator.
- Heritage status: The Raine Island Light complex, including the beacon, is listed on the Queensland Heritage Register (entry number 601527) due to its significance in the development of maritime navigation along the Great Barrier Reef and its association with the early settlement of the island.
Operational Role
The beacon serves several functions:
- Navigational safety: Provides a reference point for vessels transiting the Coral Sea, particularly those heading to ports such as Cairns, Townsville, and Mackay.
- Environmental monitoring: Assists scientific and conservation teams accessing the island for the management of the world’s largest green turtle nesting site and the critically endangered loggerhead turtle population.
- Aviation aid: Functions as a visual landmark for light aircraft operating from the island’s airstrip during research and rescue missions.
Management
Raine Island Beacon is owned and maintained by the Australian Maritime Safety Authority (AMSA) in partnership with the Queensland Department of Environment and Science, which oversees the island’s ecological protection programs. Routine maintenance is performed annually, with remote diagnostics conducted via satellite telemetry.
