Flinders Island Tourism and Business Inc. www.visitflindersisland.com.au /visitflindersisland @visitflindersisland A submission to the Rural & Regional Affairs and Transport References Committee The operation, regulation and funding of air route service delivery to rural, regional and remote communities with particular reference to: Background The Furneaux Islands consist of 52 islands with Cape Barren and Flinders Island being the largest. The local Government resident population at the 2016 census was 906 and rose 16 % between the last two censuses. The Flinders Island Tourism & Business Inc. (FITBI)represents 70 members across retail, tourism, fishing and agriculture. It plays a key role in developing the visitor economy through marketing to potential visitors as well as attracting residents to the island. In 2016, FITBI launched a four-year marketing program. The Flinders Island Airport at Whitemark is the gateway to the island. It has been owned by the Flinders Council since hand over by the Commonwealth Government in the early 1990’s. Being a remote a community the airport is a critical to the island from a social and economic point of view. It’s the key connection to Tasmania (Launceston) and Victoria. The local residents must use air transport be that for health or family reasons. The high cost of the air service impacts on the cost of living as well as discouraging visitors to visit the island. It is particularly hard for low income families. The only access via sea is with the barge, Matthew Flinders 11, operated by Furneaux Freight out of Bridport. This vessel has very basic facilities for passengers and takes 8hours one way. -
Tidal Turbine Array Optimization Based on the Discrete Particle

In order to solve the problem of optimal array of tidal turbines, the discrete particle swarm optimization (DPSO) algorithm has been performed by re-defining the updating strategies of particles’ velocity and position. This paper analyzes the optimization problem of micrositing of tidal current turbines by adjusting each turbine’s position, where the maximum value of total electric power is obtained at the maximum speed in the flood tide and ebb tide. Firstly, the best installed turbine number is generated by maximizing the output energy in the given tidal farm by the Farm/Flux and empirical method. Secondly, considering the wake effect, the reasonable distance between turbines, and the tidal velocities influencing factors in the tidal farm, Jensen wake model and elliptic distribution model are selected for the turbines’ total generating capacity calculation at the maximum speed in the flood tide and ebb tide. -
Tas Talk… the Movie the Cast, Their Stories and the Best Supporting Actress…Tasmania
TAS TALK… THE MOVIE THE CAST, THEIR STORIES AND THE BEST SUPPORTING ACTRESS…TASMANIA Kayaking on the Pieman River © Michael Walters Photography Behind the Scenes, Hobart © HypeTV –––– A journey to Tasmania is a rare chance to disconnect from stress and reconnect with the things that matter. Geographic isolation has contributed to unique biodiversity, and it has also fostered a rare community of creative, down-to-earth, resourceful people with time to make you feel welcome. We are all working in unusual circumstances and although this year we were unable to deliver our much sought after TasTalk trade event in its standard format, we know you need to connect with Tasmanian tourism operators. So, we are bringing the TasTalk trade event experience to you! This is TasTalk...The Movie, an opportunity for you to listen and connect with Tasmanians over a live platform. Featuring the stars of our tourism industry, this is set to be a movie like you have never seen before. One of the joys of travelling in Tasmania is not just the chance to taste produce straight from the farm and ocean, but the ease of meeting the makers at cellar doors, farm gates and local markets. And with four distinct seasons, there’s always something new to see, taste and feel. TasTalk...The Movie will speak to all of this and more. Tasmania is a place for adventure, however, you define it. Whether the view is from the privacy of a hot tub in a forest, or from a kayak for two, or fireside with Tassie whisky and friends, the world looks different from Tasmania. -

In this respect, the development of methodologies for the economic viability of these technologies is fundamental to the attainment of a consistent quantification of their costs and the discovery of their economic viability, while simultaneously attracting investment in these technologies. This paper presents a methodology with which to determine the economic viability of tidal energy projects, which includes a technical study of the life-cycle costs into which the development of a tidal farm can be decomposed: concept and definition, design and development, manufacturing, installation, operation and maintenance and dismantling. These cost structures are additionally subdivided by considering their sub-costs and bearing in mind the main components of the tidal farm: the nacelle, the supporting tidal energy converter structure and the export power system. Furthermore, a technical study is developed in order to obtain an estimation of the annual energy produced (and, consequently, the incomes generated if the electric tariff is known) by considering its principal attributes: the characteristics of the current, the ability of the device to capture energy and its ability to convert and export the energy. -

Bryant and Stephen Harris (with one text-figure, two tables, eight plates and two appendices) Bryant, S.L. & Harris, S. 2020 (9:xii): Overview of Tasmania’s offshore islands and their role in nature conservation.Papers and Proceedings of the Royal Society of Tasmania 154: 83–106. https://doi.org/10.26749/rstpp.154.83 ISSN: 0080–4703. Tasmanian Land Conservancy, PO Box 2112, Lower Sandy Bay, Tasmania 7005, Australia (SLB*); Department of Archaeology and Natural History, College of Asia and the Pacific, Australian National University, Canberra, ACT 2601 (SH). *Author for correspondence: Email: [email protected] Since the 1970s, knowledge of Tasmania’s offshore islands has expanded greatly due to an increase in systematic and regional surveys, the continuation of several long-term monitoring programs and the improved delivery of pest management and translocation programs. However, many islands remain data-poor especially for invertebrate fauna, and non-vascular flora, and information sources are dispersed across numerous platforms. While more than 90% of Tasmania’s offshore islands are statutory reserves, many are impacted by a range of disturbances, particularly invasive species with no decision-making framework in place to prioritise their management. This paper synthesises the significant contribution offshore islands make to Tasmania’s land-based natural assets and identifies gaps and deficiencies hampering their protection. A continuing focus on detailed gap-filling surveys aided by partnership restoration programs and collaborative national forums must be strengthened if we are to capitalise on the conservation benefits islands provide in the face of rapidly changing environmental conditions and pressure for future use. -

Tasmanian Aborigines in the Furneaux Group in the Nine Teenth Century—Population and Land
‘I hope you will be my frend’: Tasmanian Aborigines in the Furneaux Group in the nine teenth century—population and land tenure Irynej Skira Abstract This paper traces the history of settlement of the islands of the Furneaux Group in Bass Strait and the effects of government regulation on the long term settlements of Tasma nian Aboriginal people from the 1850s to the early 1900s. Throughout the nineteenth century the Aboriginal population grew slowly eventually constituting approximately 40 percent of the total population of the Furneaux Group. From the 1860s outsiders used the existing land title system to obtain possession of the islands. Aborigines tried to establish tenure through the same system, but could not compete because they lacked capital, and were disadvantaged by isolation in their communication with gov ernment. Further, the islands' use for grazing excluded Aborigines who rarely had large herds of stock and were generally not agriculturalists. The majority of Aborigines were forced to settle on Cape Barren Island, where they built homes on a reserve set aside for them. European expansion of settlement on Flinders Island finally completed the disen franchisement of Aboriginal people by making the Cape Barren Island enclave depend ent on the government. Introduction In December 1869 Thomas Mansell, an Aboriginal, applied to lease a small island. He petitioned the Surveyor-General, T hope you will be my Frend...I am one of old hands Her, and haf Cast and have large family and no hum'.1 Unfortunately, he could not raise £1 as down payment. Mansell's was one of the many attempts by Aboriginal people in the Furneaux Group to obtain valid leasehold or freehold and recognition of their long term occupation.
