Annie's love of place saw her seeking an active role in the conservation and protection of historic buildings as well as of natural places through the creation of a body like the
National Trust in England. In the 1930s, art historian
Bernard Smith remembered her as quietly but consistently discussing colonial Australia with an infectious enthusiasm that attracted sympathisers to her cause. The National Trust Provisional Committee began to fulfil Annie's dream of saving Sydney's historic sites. A program of education and public campaigns against demolition and unsuitable development in historic areas followed. Annie Wyatt, in early Trust minutes, warned the group "that the last lovely
Macquarie era buildings were in dire peril and that we should take our stand for their preservation". The 1946 Trust campaign to protect Macquarie Street against proposed developments was widely supported. The Trust produced an initial list of items to be preserved in 1946. The 'A' list included Sydney's
Hyde Park Barracks and the
Mint Building,
St James' Church, Sydney, the 1815 Military Hospital at
Observatory Hill, and
Cadmans Cottage, which all remain today as part of Sydney's central area. The list also included items further from the centre of Sydney. Old Government House at
Parramatta,
John Macarthur's Elizabeth Farm House, and
Lennox Bridge, as well as the cemeteries at
Camperdown and Parramatta, were included on this list, and have been retained. In 1946 the new Trust compiled an 'A' and 'B' list of Sydney's historic buildings and places and launched its first battle against proposed developments in
Macquarie Street. These proposals would have seen the loss of Hyde Park Barracks and the Sydney Mint Building. Many groups supported this battle which resulted ultimately in the compilation of a combined list of significant buildings within New South Wales rated by the National Trust,
Australian Institute of Architects and the
Cumberland County. As a result of these efforts, buildings on the list would be protected for future generations to learn from the past. ==Heritage protection work==
