  • Convict Labour and Colonial Society in the Campbell Town Police District: 1820-1839
    Convict Labour and Colonial Society in the Campbell Town Police District: 1820-1839. Margaret C. Dillon B.A. (Hons) Submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy (Ph. D.) University of Tasmania April 2008 I confirm that this thesis is entirely my own work and contains no material which has been accepted for a degree or diploma by the University or any other institution, except by way of background information and duly acknowledged in the thesis, and to the best of my knowledge and belief no material previously published or written by another person except where due acknowledgement is made in the text of the thesis. Margaret C. Dillon. -ii- This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968. Margaret C. Dillon -iii- Abstract This thesis examines the lives of the convict workers who constituted the primary work force in the Campbell Town district in Van Diemen’s Land during the assignment period but focuses particularly on the 1830s. Over 1000 assigned men and women, ganged government convicts, convict police and ticket holders became the district’s unfree working class. Although studies have been completed on each of the groups separately, especially female convicts and ganged convicts, no holistic studies have investigated how convicts were integrated into a district as its multi-layered working class and the ways this affected their working and leisure lives and their interactions with their employers. Research has paid particular attention to the Lower Court records for 1835 to extract both quantitative data about the management of different groups of convicts, and also to provide more specific narratives about aspects of their work and leisure.

    Impact of sea level rise on coastal natural values in Tasmania JUNE 2016 Department of Primary Industries, Parks, Water and Environment Acknowledgements Thanks to the support we received in particular from Clarissa Murphy who gave six months as a volunteer in the first phase of the sea level rise risk assessment work. We also had considerable technical input from a range of people on various aspects of the work, including Hans and Annie Wapstra, Richard Schahinger, Tim Rudman, John Church, and Anni McCuaig. We acknowledge the hard work over a number of years from the Sea Level Rise Impacts Working Group: Oberon Carter, Louise Gilfedder, Felicity Faulkner, Lynne Sparrow (DPIPWE), Eric Woehler (BirdLife Tasmania) and Chris Sharples (University of Tasmania). This report was compiled by Oberon Carter, Felicity Faulkner, Louise Gilfedder and Peter Voller from the Natural Values Conservation Branch.

    Journal of Australasian Mining History, Vol. 18, October 2020 Briseis water supply scheme 1901-1910: a premium investment By KEITH PRESTON Key words: Tin mining, Tasmania, water management, hydraulic sluicing, water rights, aqueducts. t the close of the nineteenth century, mining of deep tin leads along the Ringarooma Valley of north-eastern Tasmania by means of hydraulic sluicing A was well established. In the vicinity of Derby, water supply and tailings disposal were critical factors in achieving viable operations along the Cascade Lead.1 Mines on the south bank of the Ringarooma River competed for available water from the Cascade River, that flowed through the leases of the Briseis Tin Mining Company.2 A limited water supply was also available from Main Creek to the east, but again restricted by competition from mine leases along that watercourse. Reduced summer flows usually curtailed tin production for several months as finance for the construction of storage reservoirs was generally unavailable. Figure 1: Sketch plan of the Cascade Lead showing original lease owners with subsurface features superimposed. Source: The Argus, 29 April 1902, p. 8. 134 Keith Preston On the south bank of the Ringarooma River the privately owned Krushka Brothers mine on Lease 316 dominated tin output prior to 1900, aided by a short headrace from the Cascade River that provided an adequate water supply and a river frontage that facilitated tailings disposal at minimal cost (Fig. 1).3 The adjoining mines operated by Victorian based mining companies, the New Brothers’ Home No. 1 TM Co.

Distribution of acid sulphate soils in Tasmania Dr Shivaraj Gurung FOREWORD Acid sulphate soils are pyritic sediments that can produce acid when exposed to oxidising conditions. These sediments typically occur in low-lying coastal areas, backswamps and in estuarine environments. The acid drainage resulting from the disturbance of acid sulphate soils can dissolve and mobilise toxic metals which can enter the receiving environment, causing serious damage to the aquatic ecosystem. Acid water and heavy metal pollution from the disturbance of acid sulphate soils is a major strategic environmental issue for management of coastal regions around Australia. Section 36.1 of the Tasmanian State Policy on Water Quality Management (1997) requires that “a survey is carried out to identify Tasmanian soils and surface geology with the potential to give rise to highly acidic drainage if disturbed or developed”. This reconnaissance investigation provides a basis for this objective. The program is a component of the proposed State Water Quality and Quantity programs and was largely funded by the National Heritage Trust. Water analyses were carried out by the Department of Primary Industries, Water and Environment at the Analytical Services Tasmania laboratory. Geochemical analyses, map production and project management were carried out by Mineral Resources Tasmania.
