Distribution

This community occurs in the New South Wales North Coast and SouthEastern Queensland bioregions and on Curtis Island in the Brigalow Belt NorthBioregion. This encompasses an area from just north of Newcastle, NSW (aroundRaymond Terrace) in the south, to just north of Gladstone in Queensland in thenorth.


Habitat and ecology

  • is found on alluvial landforms, including floodplains, the riparian zones of rivers and tributaries, alluvial flats, floodplain/alluvial terraces and periodically flooded depressions.
  • occurs on alluvial and colluvial soils which are usually deep (over 1 m), including silts, clay loams, clays and sandy loams, gravel and cobbles.
  • does not typically occur on soils that are primarily marine or aeolian sand.
  • generally occurs at below 50 m above sea-level (ASL), although it can occur up to 250 m.
