Native to eastern Queensland and northern New South Wales (i.e. from Cooktown in northern Queensland south to the central regions of New South Wales).
Naturalised beyond its native range in the coastal districts of southern and central New South Wales. Also naturalised in south-western Western Australia (i.e. between Perth and Albany) and south-eastern South Australia, and possibly naturalised in southern Victoria.
Naturalised overseas in Hawaii and on La Réunion.
This species is regarded as a minor environmental weed in south-western Western Australia and some parts of New South Wales (e.g. in the wider Sydney and Blue Mountains region), and as a "sleeper weed" in other parts of southern Australia.
Lacy tree fern (Cyathea cooperi) has escaped cultivation and invaded native vegetation along streams and around swamps in south-western Western Australia. Similarly, it is well established in moist gullies and along creeks in bushland in the Sydney region (e.g. in Lane Cove National Park). It has also become a serious weed of rainforests on some of the Hawaiian islands.
