an important forerunner to the implementation of the Sydney Bush School landscape design philosophy in public parks. Illoura Reserve is a seminal work of landscape architecture by one of the pioneers of the Sydney Bush School movement, Bruce Mackenzie, who created a landscape which was instrumental in changing public expectations in the design of public open space. Iloura Reserve was part of a movement towards environmentally conscious landscape design that was respectful of the special qualities existing in a place; retaining natural rock formations; reintroducing native vegetation; and interpreting the former industrial character of the place through the use of robust recycled timbers and sandstone blocks. The reserve was designed to provide an alternative to the ordered European based designs common in public parks at that time and provided the park user with a bush retreat within the city. The reserve is held in very high esteem by the landscape and architecture professions and by the local community of East Balmain as well as the wider community of Sydney. Iloura Reserve was listed on the New South Wales State Heritage Register on 29 November 2013 having satisfied the following criteria. The place is important in demonstrating the course, or pattern, of cultural or natural history in New South Wales.

The reserve design inspired a change in public attitudes to public open space resulting in the desire for an alternative to the ordered neat environments common to public parks and heralded the beginning of the concept of ecologically sustainable design used in public projects. Illoura Reserve shows a high degree of creative or technical achievement for the 1970s. The design of the reserve was instrumental in changing the approach to design of harbourside parks and other public spaces. The Sydney Bush School approach to landscape design was indicative of the increased usage of indigenous plants and their introduction into mainstream gardens. Illoura Reserve influenced later generations of landscape designers in Australia. Illoura Reserve at Peacock Point is described by the Australian Institute of Landscape Architects to be a critical contribution to Australian landscape architecture. The place has a strong or special association with a person, or group of persons, of importance of cultural or natural history of New South Wales's history. The designer of Illoura Reserve, Bruce Mackenzie, is one of Australia's most
