Wilsons Promontory Lighthouse, Lighthouse at South East Point, Victoria, Australia

Wilsons Promontory Lighthouse is a 19-metre granite tower on South East Point, the southernmost lighthouse on mainland Australia, about 18 kilometres from Tidal River. The tower and the keeper's cottage beside it were built from locally quarried granite, and the site gives near-360° views over Bass Strait.

Construction began in 1853 using convict labor and local granite, with completion in 1859 to guide ships through Bass Strait. The lighthouse was built in response to many shipwrecks along this dangerous coastline.

The keeper's cottages show how lighthouse families lived and worked in this isolated location. The buildings reflect the daily routines and challenges of maintaining a vital navigation post far from towns.

The lighthouse site is reached via a walking trail of about 18 kilometers from Tidal River and requires good physical fitness. Accommodation in the keeper's cottages can be arranged in advance and offers basic facilities for overnight stays.

The lighthouse and keeper's cottage were built from granite quarried locally, and the lightstation is listed on the Commonwealth Heritage List in Victoria. From 1869 to 1878 the keeper was Captain Thomas Musgrave, a figure known for his earlier shipwreck survival on Auckland Island.
