Situated in the heart of the mulga lands, Thrushton National Park conserves a remnant of original vegetation within an area of extensive clearing. Gazetted in 1990, the park consists of flat, sandy plains and levees containing large stands of mulga and areas of spinifex with scattered ironbark, cypress pine and kurrajong. Neabul Creek, which flows through the park, is lined with river red gums and coolibahs.

The ruins of Thrushton homestead and surrounding station buildings are a reminder of the area's previous 'life' as a sheep property. Thrushton house was originally part of the Dunkeld Inn and was moved to Thrushton on carts drawn by 40 horses in 1921.

A diverse collection of plants and animals thrive within Thrushton. At least 100 species of birds have been recorded here, while mammals such as koalas and echidnas frequent creek-lines. The rare and threatened yakka skink, Major Mitchell cockatoo, square-tailed kite, rough-collared frog and woma are found here. Other species, including belah Casuarina cristata subsp. pauper, the delicate mouse and the golden whistler are near the south-western limit of their range in this park, while some 'western' species, such as the skinks Ctenotus brachyonyx and C. schomburgkii, are here at the eastern-most limit of their distribution. Spring wildflowers are a special feature of this park.
