The park dates back to pre-colonial New South Wales, with original and widely diverse flora and fauna:[2] ...Boronia Park is the best place to gain an idea of Hunter's Hill's pre-European landscape, as it has the largest intact stretch of bushland.

Towards the top of the slope is an area of Kunzea ambigua shrubland, while Blackbutt, Eucalyptus pilularia grow on the more sheltered aspects, and a small creek tumbles down a steep waterfall to form a pool beside Grey Mangroves along the river's edge...the Turpentine-Ironbark forest's only remnant in Hunters Hill today is a small stand of Syncarpia glomulifera, with some understorey shrubs, near the entrance to Boronia Park...The park was named after the Boronia ledifolia which is all but locally extinct, probably due to the introduction of rabbits in the 19th century.

[citation needed] The Boronia Park is bordered in Hunters Hill by Park Road to the west, High Street to the north, Ryde Road to the south and the Lane Cove River and Boronia Avenue to the east.

Boronia Park Reserve contains Brickmakers Creek where the water flows over Tipperary Falls, a 10-metre (33 ft) high waterfall on a Hawkesbury sandstone escarpment before entering the Lane Cove River through a tidal pool lined with saltmarsh, mangrove, Avicienna marina and Casuarina glauca.

[3] The Great North Walk passes through Boronia Park just downstream of Tipperary Falls.
