The site was identified as internationally important for bird conservation in 2009 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Musk Duck Biziura lobata	LC	resident (1986–2007)	50–2,302 birds	A4i
Australian Shelduck Tadorna tadornoides	LC	resident (1986–2007)	3,000–13,782 birds	A4i
Banded Stilt Cladorhynchus leucocephalus	LC	non-breeding (1986–2008)	2,500–18,000 birds	A4i
Hooded Plover Thinornis cucullatus	VU	resident (1998–2007)	37–170 birds	A1, A4i
Red-necked Stint Calidris ruficollis	NT	non-breeding (1986–2005)	328–15,000 birds	A4i

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Residential and commercial development	likely in long term (>4 years)	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed
