This ecosystem occurs on coastal dunes across the Sunshine Coast region primarily behind the frontal dunes in the swales.
The Queensland biodiversity status is Of Concern, however it is upgraded to Vulnerable on the Sunshine Coast due to the threats posed by weed invasion, recreation and fire.
Prior to European settlement the extent of this regional ecosystem on the Sunshine Coast was restricted to only 31 hectares. Over 60% of this ecosystem has since been lost with 19 hectares remaining today. 90% of this extent is protected in either state or council protected tenures.

Management considerations
One of the main threats to this ecosystem is from weed invasion generated by encroachments of invasive non-native plants and dumping of green waste from home gardens.
Other threats to the maintenance of ecosystem biodiversity are caused by inappropriate recreational use, arson, illegal vegetation removal, unauthorised structures and paths as well as changes in hydrology i.e. draining of the water table.
Some of the common garden weeds regularly removed from this ecosystem include:
| Baccharis halimifolia | Groundsel bush |
| Bryophyllum ssp | Mother of millions |
| Callisia fragrans | Purple succulent |
| Ipomoea cairica | Coast morning glory |
| Lantana camara | Lantana |
| Murraya paniculata | Mock Orange, Orange Jessamine |
