The floodplains, braided channels and waterholes of the Diamantina River and its tributaries are lined with coolibahs, river red gums, lignum, blue bushes and grasses. Beyond the river flats are vast gibber plains and deep, cracking clay soils supporting grasslands dominated by Mitchell grass. In the south-west, sandhills and claypans are dominated by cane grass communities, while stark limestone ranges in the park's centre support shrubland and grassland communities that are rare in the region. Two rare Eremophila species—rock fuchsia bush and gypsum bush—are found in the park. To date, the gypsum bush has been recorded in only 10 locations on and around Diamantina. Trees such as lancewood, mountain yapunyah, Normanton box, red mallee and myall, although more typically found in greater numbers in other climatic regions, are also found here.
