The mine once employed over 2,000 workers, making it the primary economic driver for the town of Wonthaggi.
During its peak, the mine produced over 600,000 tonnes of coal annually to fuel the Victorian Railways steam locomotive fleet.
The mine was closed in 1968 due to the transition of the Victorian railway network from steam to diesel and electricity.
The underground tunnels span a vast network, though only a small, reinforced section is open to the public for safety.
The 'poppet head' structure remaining on-site was a critical piece of infrastructure used to lower miners and haul coal to the surface.
The State Coal Mine in Wonthaggi is the only historic coal mine in the Southern Hemisphere offering visitors a genuine underground tour. Established in 1909 to provide coal for Victoria's railways, the site operated until 1968 and produced nearly 17 million tonnes of coal. The heritage area features original mining buildings, including the lamp room and poppet head, spread across an expansive outdoor precinct. Visitors can descend into the mine tunnels via a guided tour to experience the cramped, damp, and dark conditions miners faced. The surface grounds also house an interactive museum displaying mining equipment, historical photographs, and personal effects of the former workforce. The site serves as a testament to the industrial heritage of the Gippsland region.
The elevated viewing platform near the heritage poppet head provides the best vantage point for capturing the entire industrial site.
Book underground tour tickets in advance online, as capacity is limited and tours often sell out.
Bring a light jacket as temperatures in the underground tunnels remain cool throughout the year.
Explore the surface walking trails to see the remnants of original railway tracks and machinery.
Do not attempt to explore the restricted areas or the fenced-off abandoned tunnel shafts for safety reasons.
The underground mine tour may be suspended during periods of heavy rain or maintenance; check official park notices before visiting.
Wear sturdy, closed-toe footwear suitable for uneven, damp ground. Visitors must wear provided safety helmets during underground tours.
