Botanic Gardens Trust, Sydney, Australia


Fast Facts


The Australian Botanic Garden, Mount Annan, est. 1988, showcases Australian flora amongst rolling hills and lakes in Sydney’s suburban south-west. It is the largest botanic garden in Australia. Situated on former farmland, it contains remnant Cumberland Plain Woodland, a critically endangered ecological community of the region.

The Trust’s horticultural research facilities are based at the Garden, including the NSW Seedbank that will be a key component of the Trust’s new research and conservation facility, Plantbank, when it is completed in mid-2013.

The Garden’s abundant native animal and birdlife, picnic areas, barbecues, lakeside lawns, walking and cycling tracks and large contemporary sculptures make it a popular recreational destination for the local community. Due to its large size, it allows access to cars and bikes.

The Australian Botanic Garden, Mount Annan, has free entry.

European history of the estate

The Australian Botanic Garden, Mount Annan opened on 2 October 1988 as a project for the Bicentenary of Australian settlement. The land in one of Australia’s earliest farming areas had been purchased for the Glenlee Estate in 1820 and sold in the 1850s to James Fitzpatrick whose descendants ran a dairy farm until 1978.
