Postboy (ship)
 The 63 ton schooner Postboy was built at Port Adelaide in 1874. The schooner was owned by Messrs. Weman and Morgan and registered at Port Adelaide. She was a regular trading vessel between Port Adelaide and the gulf ports. Captain James Thomas was in charge of the schooner Postboy on 15 December 1876 about 11-12 miles (20 km) off Glenelg when a sudden squall struck.
