State Coal Mine

Section of restored underground tunnel in Division One.

The State Coal Mine, also known as State Coal Mine Heritage Area, is a former 20th century state-owned black coal mine located in Wonthaggi, Victoria, Australia. The mine was operational from 1910 until 1968 and is now a state park and tourist attraction. Contents The coal deposits at the site are estimated to be more than 150 million years old and the tunnels of the mine encompass nearly 5,000 kilometres (3,100 mi), forming an underground ring around the town of Wonthaggi. The site is located adjacent to the former railway line to Melbourne via Wonthaggi.
