Creal Reef Light is an active lighthouse located at Creal Reef, a planar reef about Шаблон:Convert east of Mackay, Queensland, Australia. It guides ships outgoing from Mackay into Hydrographers Passage, a deep water channel east of Mackay.[1] The structure is a stainless steel tower, which also serves as a daymark and carries a racon.

Creal Reef is a middle shelf planar reef with an area of Шаблон:Convert.[2] It was named in the late 1920s by Captain John A. Edgell (RN) on the survey ship HMAS Moresby, during the Moresby survey of the Cumberland Channel inside the Great Barrier Reef.[3] It was named after Denis A. J. Creal, a pilot with the No. 101 Flight RAAF who assisted the Moresby with her surveys.[4]

Structure and display

The structure, established in April 1985, is a Шаблон:Convert stainless steel skeletal tower with a white lantern, standing on a reinforced concrete hut, supported on four piles. The total height from the ground to the top platform is Шаблон:Convert.[5] The light shares the location with an automatic weather station.[6]

The current light characteristic is a white flash every 7.5 seconds (Fl.W. 7.5s) visible for a distance of Шаблон:Convert.[7] The apparatus is a solar powered VRB-25 rotating at 1.33 rpm. The light source is a 12 Volt 75 Watt Halogen lamp with an intensity of 104,000 cd.[5] The racon, mounted at an elevation of Шаблон:Convert,[8] transmits a morse code "M" (- -) for a distance of Шаблон:Convert.[9]

The daymark, displayed at Шаблон:Convert above MHWS, comprises two orange Шаблон:Convert slats on the northern and western faces.[5]

Site operation and visiting

The site and the tower are operated by the Australian Maritime Safety Authority.[5] The island is accessible only by boat, and both the site and the tower are closed to the public.[1]
