Briefings

Research indicates Lady Elliot Island hosts two lighthouses, with visitors reporting a third phantom lighthouse beam. The first lighthouse operated from 1873 until 1995, after which the second took over. This phenomenon is attributed to the island's unique geography and lighting conditions, creating a persistent visual illusion for observers.

Key points

• Two lighthouses exist on Lady Elliot Island, with the first built in 1873 and decommissioned in 1995 when the second assumed duty.
• Visitors consistently report seeing a third, non-existent lighthouse beam on the horizon at night.

Context

Located at Australia's southernmost tip, Lady Elliot Island features a complex reef system that creates unique lighting conditions. The historical transition from the first to the second lighthouse in 1995 marks the end of the first era, yet the phantom lighthouse remains a persistent visual anomaly for island residents and tourists.

Limitations

The evidence is limited to visitor reports of a phantom lighthouse beam. No physical data or measurements confirm the existence of the third lighthouse. The phenomenon is described as a visual illusion rather than a confirmed physical structure.
