About Sea Hill Lighthouse

Also known as: Sea Hill (Range Rear)

Constructed in 1895, the Sea Hill Lighthouse is a cylindrical iron tower standing 13 meters tall, with its focal height reaching 33 meters. It exhibits a white light with one flash every 6 seconds, visible for 15.9 nautical miles. The tower's exterior is painted white and red. Originally serving as part of a pilot station that closed in 1963, the lighthouse was later reported deactivated in 2006 and demolished in 2009, though it has since been granted State Heritage status. It is situated on a promontory at the northwestern point of Curtis Island, marking the eastern side of the entrance to Keppel Bay.

Why it matters: This lighthouse served to mark the eastern entrance to Keppel Bay, guiding vessels toward Rockhampton and Port Alma. Its recognition as a State Heritage site in 2011 acknowledges its contribution to Queensland's maritime history.
