The gardens receive assistance from the Royal Botanic Gardens Trust’s Community Greening program, set up to assist social housing tenants with community gardening, a partnership between the Trust and Housing NSW.
Cook Community Garden was the first of the three gardens to be established with the assistance of Housing NSW and South Sydney Council (since amalgamated with City of Sydney).
Community worker, Rhonda Hunt, who started the Waterloo Community Garden at the Raglan Street Uniting Church in 1991 was then working for South Sydney Council and was instrumental in assisting the Cook Community Garden start-up, along with Prue Rheuben from UNSW, which maintained offices on the estate to train community workers.
The CGA (formally Australian City Farms & Community Gardens Network) provided training for the multicultural Cook gardeners, through a Russian translator. The three gardens are fenced, feature signage announcing the garden, seating, garden allotments, and are used mainly for vegetable production for the residents of the social housing estate high rise.
