  • Freycinet Resort Development
    FREYCINET RESORT Expansion and Development Plans DESCRIPTION Stylish, comfortable accommodation in a wilderness setting on Tasmania’s beautiful East Coast. Freycinet Resort is a ten-cabin ecofriendly resort situated at Mt. Paul on the edge of the Freycinet National Park near Coles Bay on Tasmania’s beautiful East Coast. The resort has received development approval from Glamorgan Spring Bay Council to build an additional 28 units as visitor accommodation, a redeveloped reception, restaurant, and amenities building as well as a number of additional units as staff accommodation. The resort aims to provide a luxury experience for a reasonable price, striving for superior customer service for its guests. Situated on top of Mt. Paul the resort boasts skylines to both Friendly Beaches and across the Freycinet Peninsula. It is peppered with high quality art – sculptures and installations for visitors to experience as they wander the property. We also have a license to operate a guided walking experience through the fire trails and tracks of the Freycinet National Park which will be operated with the Resort as its base. Once the resort is increased in size to 38 units and with the guided walking experience that resort will contribute to the goal of increased visitation. Once the Tasmanian borders are open to tourists once again this will be a key contribution to East Coast tourism visitation and yield and the recovery from the impact of COVID-19. Aligning strongly with the T21 Visitor Economy Action Plan 2020-2022 this development will contribute to the recovery from the effects of COVID-19 on our tourism sector.

  • Sorell Council Area– Community Food Access Profile
    SORELL COUNCIL AREA– COMMUNITY FOOD ACCESS PROFILE Introduction & disclaimer – This profile has been developed by the Heart Foundation Tasmania as part of the Healthy Food Access Tasmania Project. The information highlighted in this profile was gathered in 2014/15 and it provides an overview for the local government area. For any questions or additional information please contact the Heart Foundation. Why does access to healthy food matter? Limited or poor access to healthy food has both health and social consequences. There are many health conditions and diseases which are associated with or caused by a poor diet, as a result of poor economic or physical access to healthy food. These diseases include heart disease1, diabetes2, some cancers3 and other health conditions such as overweight4 and obesity5. Reduced access to healthy food can cause poor physical development in children and impact their learning and attendance at school6. For adults who have poor access to healthy food it is often very stressful and causes them to be anxious and ashamed7. This often also means they avoid social occasions in their communities and with family and which can lead to them becoming socially isolated8. How are the residents of Sorell doing? Currently 49.9 % of adults living in Sorell eat the recommended two pieces of fruit per day and 7.6 % eat the recommended five serves of vegetables, compared with 42% and 9.8% for state averages9. Sorell residents are eating more fruit and but less vegetables in 2013 when compared with 2009. For adults living in Sorell, 21.5 % are obese9. Compounding this 17.2 % of Sorell adults report that their health is poor or fair, although this is less than the 19% state average10.

Included in this reserve system is the Tasmanian Wilderness World Heritage Area (TWWHA), itself comprising an area of around 1.38 Inside... million hectares or around 20 percent of Tasmania. This area is one of only two World Heritage Areas in the world which satisfies at least seven of the ten criteria required for WHA listing. In total, this collection of national parks and reserves constitutes one of Tasmania - Tasmania’s most important assets.
