    GRAYTHWAITE – CONSERVATION MANAGEMENT PLAN APPENDIX B HISTORICAL OVERVIEW TANNER ARCHITECTS B-1 GRAYTHWAITE – CONSERVATION MANAGEMENT PLAN B-2 TANNER ARCHITECTS GRAYTHWAITE – CONSERVATION MANAGEMENT PLAN HISTORICAL OVERVIEW 1.1 Introduction The following historical overview builds upon the history prepared for the Conservation Plan for the Graythwaite site prepared by Graham Edds & Associates in 2000. 1.2 Nineteenth Century Development of North Sydney 1.2.1 Land Grants Graythwaite is located within the 39 acre land grant made to Thomas Walker in 1832. Walker’s grant was one of a number made in the early decades of the nineteenth century that form the backbone of non-indigenous development in North Sydney. The first grants were located on the foreshore of Sydney Harbour and the present day topographical features of this shoreline are named after the grantees. These early grants were to William (Billy) Blue in 1817, Edward Wollstonecraft in 1820, and James Milson in the mid-1820s. Blue’s 80 acres is located on the peninsula now known as Blues Point. Blue was a Jamaican Negro who had arrived in Sydney in 1801 to serve his sentence of seventeen years’ transportation. By 1807 Blue was providing a ferry service between Sydney and the north shore of the harbour and in later years was appointed the waterside watchman. He died in 1834, and his son continued the ferry service. Over the 1830s parts of the grant were sold off, with the remains of the estate sold in 1844. The northern boundary of Blue’s grant defined the southern boundary of Walker’s grant.

Page 1 of 8 IN THE SUPREME COURT OF NEW SOUTH WALES EQUITY DIVISION WINDEYER J TUESDAY 14 AUGUST 2007 1994/06 NORTHERN SYDNEY AND CENTRAL COAST AREA HEALTH SERVICE & ANOR V ATTORNEY-GENERAL FOR NEW SOUTH WALES & ORS JUDGMENT 1 These are charitable trust proceedings under the Charitable Trusts Act 1993 in which it is sought that a cy-prés scheme be settled and ordered. As is usual in these cases there is to be a two stage hearing if it is found a scheme is justified. 2 The question for decision in this part of the case is whether the charitable purposes for which “Graythwaite” was given by Mr Thomas Allwright Dibbs (later Sir Thomas Dibbs) to His Majesty King George the Fifth on behalf of the Government of the State of New South Wales, can no longer be carried out. If it is decided that the trust purposes have failed, then it will be necessary to have a later hearing to settle a cy-prés scheme for the purpose of carrying out as nearly as possible the original trust purposes. Facts 3 The trust was created by memorandum of transfer and surrender under the Real Property Act 1900 from Thomas Allwright Dibbs to His Majesty the King for the State of New South Wales, which transfer was accepted by the Crown Solicitor on behalf of the transferee. The document is dated 1 October 1915 and omitting references to certain rights of way, is as follows: MEMORANDUM OF TRANSFER (Real Property Act 1900) A206747 In consideration of my admiration of and sincere sympathy for

Sayers, William Tunks and Colonel Distance: 4.6 km George Barney. On this walk we will also Approximate time: 3.3 hours view changes in the North Sydney Grading: medium to high landscape over the past 150 years since the people of NSW elected their first Parliament. North Sydney has always been unashamedly conservative but sometimes independent in its political leanings (especially in more recent times with Ted Mack and Robyn Read). Labor members at state and federal level have been rare, unless they had a maverick past. William Morris Hughes, for example, was a right wing politician who represented North Sydney but had started his political life on the left. By the 1880s the North Shore of the harbour had become a desirable living area, attracting professionals and businessmen who worked in the city and commuted by the steamers. A cluster of early political representatives lived in the central portion of North Sydney, yet others lived in Kirribilli and Neutral Bay. Unfortunately some of the homes of our politicians have been demolished to make way for development in the Central Business District and construction of the Sydney Harbour Bridge and Warringah Expressway.

The findings are to be incorporated into a Conservation Management Plan (CMP) for the site, currently being prepared by Tanner Architects. The majority of registered AHIMS sites in the region of the study area are middens and Hawkesbury Sandstone shelters, which occur along Sydney Harbour. However, there are no registered AHIMS sites in the study area or in its vicinity, and no new Aboriginal sites or areas of Aboriginal heritage sensitivity were identified during the survey. This confirms the predictive model, and was expected given the early development of the area of North Sydney. Given the extent of disturbance to the original land surface at Graythwaite and the steep topography, it is not considered that there is any archaeological potential for intact or substantial Aboriginal heritage deposits on the site.

  • It Was a Very Close Community Page 2
    “It was a very close Introduction The Union/Bank/Thomas Street Conservation community” Area is largely contained within two major residential subdivisions of the mid-nineteenth A walking tour of the century. The area immediately south of Union Union/Bank Street Conservation Street was part of William Blue’s 50-acre land Area, McMahons Point grant, part of which was inherited by his daughter Susannah, and subdivided in 1859 by Distance: 3.5 km her husband William Chuter. Whilst to the north Approximate time: 3 hours of Union Street is the 1870s subdivision of Grading: low to medium Edwin Sayers ‘Euroka’ Estate. The land was originally owned by the Cammeraygal people. Their numbers and social structures were devastated in the decades following colonization and land was being given away to colonists from the late 1800s. In 1817 Governor Macquarie gave a grant of 80- acres of land on the North Shore to ex-convict William Blue and he named this area, encompassing the present day suburb of McMahons Point, ‘Northampton Farm’. This was a working farm on which he and his family cultivated vegetables and fruit for the Sydney market. Prior to receiving his land grant he was living in the Rocks and had started the first ferry service across the Harbour from Dawes Point to Blues Point in 1807. After Blue’s death in 1834 Northampton Farm was divided up amongst his children William, Robert, John, Susannah and Mary. And contrary to his will, the family began to subdivide and sell portions of the property from as early as 1836.

  • GRAYTHWAITE Graythwaite Is a Magnificent Three-Storey Sandstone Mansion, Built in Stages Between 1832 and 1875
    North Sydney Heritage Leaflet 23 GRAYTHWAITE Graythwaite is a magnificent three-storey sandstone mansion, built in stages between 1832 and 1875. It was listed on the Register of the National Estate in 1978. It is one of North Sydney’s most historically significant houses. Given the extent of the surviving grounds with its outhouses, important 19th century garden plantings, but also its association with the prominent Dibbs family, through the 1915 bequest of Thomas Dibbs, its link to the history of ANZAC and the home front during World War One. As the possibility of its sale to private interests emerged in the 1990s, the site also became the focus for a passionate, but ultimately unsuccessful, campaign by local residents and North Sydney Council to keep the property in public ownership. The land on which Graythwaite is situated was granted by purchase to Thomas Walker, a Deputy Assistant Commissary - General for whom Walker Street in North Sydney is named. A part of the land consisting of 39 acres was soon after transferred to William Miller, the Assistant Commissary- General, for whom Miller Street is named. Additional land was transferred to William Lithgow, NSW Engineer-in-Chief of Railways, who also lived in North Sydney and for whom the city of Lithgow is named. Walker built a house on his estate known as ‘Euroka’. When Walker died in 1850, this house passed to his widow who later sold it to George Tuting. This ownership was short-lived, however, and it was sold again to Edwin Mawney Sayers, a wealthy shipping merchant. Sayers added a substantial new wing to Walker's house.

  • GW 01 Introduction.Doc GRAYTHWAITE – CONSERVATION MANAGEMENT PLAN
    GRAYTHWAITE UNION STREET, NORTH SYDNEY CONSERVATION MANAGEMENT PLAN prepared for SYDNEY CHURCH OF ENGLAND GRAMMAR SCHOOL FINAL ISSUE P4 – NOVEMBER 2010 TA JOB No. 09 0821 52 ALBION STREET SURRY HILLS NSW 2010 GRAYTHWAITE – CONSERVATION MANAGEMENT PLAN PREFACE A new conservation management plan (CMP) for Graythwaite has been prepared as the endorsed earlier CMP, prepared in 2000, is now due for re-consideration and re-endorsement. It has also been prepared to address the changed circumstances relating to the place and to acknowledge that other options for its future management and use may have a more preferable heritage outcome. The Shore School purchased Graythwaite House and Lands from the State government on the understanding that it would, amongst other things, retain and conserve the heritage significance of the place. It is also Shore’s understanding that it is entitled, as owner, to reasonable use of the place. The Shore School purchased the property with the earlier (revised) CMP issued by the State government as a guiding document for potential purchasers. The earlier CMP allowed for new construction on Union Street. The School, in view of the recommendations contained in this updated CMP, has decided not to pursue this option in the public interest. The Shore School, however, needs to relocate the development potential to elsewhere on the Graythwaite lands—with the northwest corner identified as the area with the least potential for impacts. The earlier CMP also advocated the removal/replacement of the Ward Building and this approach has been retained. A more recent study has established that the new support facilities for the site could be located in a similar location with minimal impacts on the heritage significance of the place.

  • North Sydney Federation Walk
    NORTH SYDNEY’S HERITAGE 32 FEDERATION FACES AND PLACES IN NORTH SYDNEY: A WALKING TOUR A guided walk around the streets and laneways of North Sydney focusing on our Federation connections, including the former residences of Sir Joseph Palmer Abbott, Sir Edmund Barton and Dugald Thomson. Along the walk, view the changes in the North Sydney landscape since Federation and the turn of the 20th century. FEDERATION 1901 – BACKGROUND HIGHLIGHTS At the turn of the year 1900 to 1901 the city of Sydney went mad with joy. For a few days hope ran so high that poets and prophets declared Australia to be on the threshold of a golden age… from early morning on the first of January 1901 trams, trains and ferry boats carried thousands of people into the city for the greatest day of their history: the inauguration of the Commonwealth of Australia. It was to be a people’s festival. Manning Clark, Historian It was also a people’s movement and 1901 was the culmination of many years of discussions, community activism, heated public debates, vibrant speeches and consolidated actions. In 1890 the Australasian Federal Conference was held in Melbourne and the following year in Sydney. In 1893 a meeting of the various federation groups, including the Australian Native Association, was held at Corowa. A plan was developed for the election of delegates to a convention. In the mid to late 1890s it was very much a peoples’ movement gathering groundswell support. In 1896 a People’s Convention with 220 delegates and invited guests from all of the colonies took place at Bathurst - an important link in the Federation chain.

  • Graythwaite – Conservation Management Plan
    GRAYTHWAITE – CONSERVATION MANAGEMENT PLAN 2 HISTORICAL OVERVIEW 2.1 Introduction This section of the CMP summarises the analysis of available documentary evidence for Graythwaite. It draws from the historical research undertaken by Nick Jackson (see Appendix B). It also draws from the analysis of the cultural landscape by CAB Consulting Pty Ltd and the historical archaeological assessment of the Graythwaite site prepared by Casey & Lowe. 2.2 The Natural Environment Very little of the indigenous flora are now represented within the Graythwaite site but it once supported varying extents of heath, woodland and forest vegetation formations associated with the Hawkesbury Sandstone. The dominant woodland trees may have been Eucalyptus pilularis ( Blackbutt) associated with the shale and associated with the sandstone; Angophora costata ( Sydney Red Gum) and Corymbia gummifera (Red Bloodwood) trees together with a great diversity of shrubby plants interspersed with sandstone outcrops creating slopes of informal terraces. The upper slopes were also exposed to the south and west. 2.3 Aboriginal Occupation Graythwaite forms part of the traditional lands of the Darug Nation and more specifically the Gamaragal clan group who occupied the north side of Port Jackson and to the northwest opposite Sydney Cove. Very little is known about the use of the area by Aboriginal people however it is known that Aboriginal occupation was often focused on prominent landforms such as ridges, on which Graythwaite stands, which were favourable locations for camping and travelling and from which surrounding plant and animal resources could be viewed. Conversely, the steep slopes within the Graythwaite site would have been less favourable.

  • Orthotic/Prosthetic Practices 2019: New South Wales Orthotics and Prosthetics in Australia
    Orthotic/Prosthetic Practices 2019: New South Wales Orthotics and Prosthetics in Australia Orthotist/prosthetists assess the physical and functional limitations of people resulting from disease, illness, trauma and disability, including limb amputation, diabetes, arthritis and neuromuscular conditions, such as stroke. Orthotic and prosthetic services may involve the provision of orthoses and prostheses to restore function, prevent deterioration, and improve quality of life. Orthotist/prosthetists are commonly employed in Australian hospitals, private clinics, research institutions as well as rural and remote regions, working independently and as part of multidisciplinary healthcare teams to support the Australian community. Orthotist/prosthetists are tertiary qualified allied health professionals. An Australian Qualification Framework level 7 is required to practice as an orthotist/prosthetist in Australia, consistent with education standards for other allied health professions. Orthotic/prosthetic students complete training alongside physiotherapy, podiatry and occupational therapy students. The Australian Orthotic Prosthetic Association (AOPA) is the peak professional body for orthotist/prosthetists in Australia, with certified practitioners comprising 80% of the practicing profession. AOPA is responsible for regulating the profession and is a founding member of the National Alliance of Self Regulating Health Professions (NASRHP) in partnership with other professional organisations, including Speech Pathology Australia, the Australian
