Statement of Significance
What is significant?
The Wonthaggi State Coal Mine Eastern Area operated from 1919 to 1947. The Historic Reserve site includes the underground mine areas of the original No.1 bench, with three tunnels and portals, embankment and footings for winding machinery, footings for brace and electricity substation, mullock and slack heaps, railway embankment, and a number of buildings and pieces of machinery brought to the site from other parts of the State Coal Mine.
At the beginning of the twentieth century black coal from New South Wales powered Victoria's railway system, gasworks and manufacturing industries. In 1909 a prolonged strike on the New South Wales coalfields threatened Victoria's economic viability, and the Victorian Government sought to end its dependence by mining its own, poorer-quality coal deposits in South Gippsland at Wonthaggi which at the time was sparsely settled and possessed no transport links with Melbourne. The first shipment of Wonthaggi coal occurred on 25 November 1909 being dispatched by bullock teams to Inverloch and thence by ship to Melbourne. Three months later transportation by rail commenced after the Railways Department constructed a line 27 miles from Nyora in the record time of ten weeks. In 1910 the Government laid out a model township and by 1921 Wonthaggi had a settled population of over 5,000 making it one of the largest towns in Gippsland.
The Wonthaggi State Coal Mine, established in 1909, developed into a huge mining complex which operated until 1968. Within the first year of operation a power station was built to supply electricity to the whole area and installation was under way of the necessary engineering works for mining, ventilation, water drainage, haulage, and coal processing. At a very early stage, the mine also had a brickworks, which operated initially to construct the power station. The mine's peak period of employment was the year 1925-26 when 1,821 men were employed. During its operational life, the Wonthaggi State Coal Mine produced 16.74 million tons, making the field the largest black coal producer in the State's history and the fourth largest in Australia.
At a separate mining area (in the Kirrak Basin) at the east of the township, mining on three separate bench areas occurred from 1919 to 1931, producing over 1.2 million tons. The Eastern Area site was the most south-easterly of the workings of the Kirrak basin and the more productive of the two main areas opened in the Kirrak basin. New infrastructure was required because the area was too far from existing plant. The No.1 bench at 242 metres was reached in 1916 but a down throw fault delayed reaching the No.2 bench at 731 metres. The No.3 bench at 1200 metres was reached in 1919. By 1920 the yield was 350 tons per day. A down cast shaft for ventilation was completed in 1922. Seams in the Nos. 1 and 2 benches were narrow and contained dirt bands, but the No. 3 bench seam was cleaner, 1 metre thick and more productive. Work began in 1924 to take the main heading through another fault to the 4th bench. This heading was used for haulage and the No. 18 shaft (No.18) was started in 1926 was used for ventilation and transport of ponies and men. Coal was first produced from the No.4 bench area in 1930.
How is it significant?
The Wonthaggi State Coal Mine Eastern Area is of historical significance to the State of Victoria
Why is it significant?
The Wonthaggi State Coal Mine Eastern Area is historically significant as part of the State's most significant black coal mine. The State Coal Mine reflects Victoria's endeavour to become self sufficient in the provision of vital black coal supplies to the State's railways and industry in the early twentieth century. The Eastern area including the underground workings has the potential to educate in relation to this important aspect of Victoria's history.
The Wonthaggi State Coal Mine Eastern Area is significant as a representative example of a black coal mine from the first half of the twentieth century. The underground workings of the Eastern Area Historic Reserve have the potential to educate on important aspects of this industry, including the technology and working conditions of mining coal by hand and the complex organisation of labour required in such a mine.

Underground Works and Haulage Ways Policy:
The aspect of the significance which distinguishes this site from the other registered parts of the State Coal Mine is the capacity of the underground workings here to be used for educational and interpretation purposes. In order for access to the underground workings to be allowed, the tunnels must be made safe to current standards. In order to make the tunnels safe large scale new works and ongoing maintenance works will be required. Some of these works will involve replacement of old material, introduction of new technologies and new tunnelling, which will compromise the intactness and integrity of the underground site. These underground works form only a small proportion of the total underground workings of the mine which will continue to have relatively undisturbed archaeological potential. In assessing permits for works in this area, the priority of allowing continued safe access will take precedence over adherence to conservation principles, and such works will be permitted. Works to the haulage line which gives access to the tunnels, some of which are above ground, will also be considered in a similar way.Where possible and suitable within the requirement to make the underground area and haulage way safe, old materials and technologies should be replaced with like materials and technologies. Original materials should be maintained where possible alongside the new replacement parts.
Assessment of permit applications for underground and haulage way works will take into account the recommendations of the following reports while they are current:
"Geotechnical and ground support assessment, underground workings, State Coal Mine, Wonthaggi", Coffey Mining 2006. (Assessed existing ground support, proposed ground support (cable bolts) and general geotechnical inspections.)
"Parks Victoria Electrical Audit State Coal Mine", Electrical Inspection Victoria Pty Ltd 2004. (This involved inspection and recommendations for both above and below ground.)
"Parks Victoria - State Coal Mine Ventilation, Fire ,Communications and Emergency Response", SP Solutions 2006
"Parks Victoria Sate Coal Mine Wonthaggi Ropeway Risk Assessment - Public access to Drift". Sinclair Knight Merz 2006
"Parks Victoria State coal Mine Wonthaggi Drift Winder Risk Assessment". Sinclair Knight Merz 2005Assessment of permit applications for underground and haulage way works will take into account the requirements of the following Acts:
The Mineral Resources Development Act 1990, Part 5 Division 3 Tourist Mine Authorities, and associated regulations within that Act. Including any relevant subsequent amendments and new acts.
The Occupational, Health and Safety (OHS) Act 2004 Mines Regulations and its associated regulations, including any subsequent amendments and new acts.The requirements for operation as a tourist mine will be taken into consideration in assessing permit applications. Such requirements may include installation, replacement or removal of non-original equipment necessary for tourist mine operations including personnel conveyances, personnel winder, electrics, handrails, safety equipment, communications equipment and interpretive materials.
Buildings Policy:
The registered buildings are those which are original buildings from the mining period of this site and original buildings from the other sections of the entire original State Coal Mine. Original buildings from this site should ideally be located in their original positions where evidence for these can be established. Registered buildings originating from other State Coal Mine areas sites may be moved within the site.Objects Policy:
The practice of bringing significant objects from other non-registered area of the State Coal Mine to this site should continue where this can be demonstrated to be necessary for safekeeping and conservation. An archaeological inventory of objects, their provenance and significance should be prepared and objects tagged. Objects which are currently unregistered but which are found to be of high significance should be put forward for addition to the register. Registered objects should be kept on registered land.
