Winchelsea South is a locality in the Surf Coast Shire, Victoria, Australia.

[1] Winchelsea South has always been a sparsely-populated rural area, with the locality most known for a brown coal mine which operated within its boundaries from 1921 until 1928, and again from 1931 to 1932,[3] and from 1943 to 1957.

It sold coal to industrial establishments in Geelong, and supplied the cement works at Fyansford.

The opening of a newer mine at Anglesea, which was said to be more easily worked, was given as a major reason for its closure.

The Wensleydale mine was flooded thereafter, becoming a lake, which has been used for water sports, and forms one of the main features of the locality today.
