Data Zone
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.

|---|---|---|---|---|
| Australasian Bittern Botaurus poiciloptilus | VU | resident (1998–2008) | uncommon | A1 |
| Banded Stilt Cladorhynchus leucocephalus | LC | non-breeding (2000–2008) | 60,000 birds | A4i |
| Double-banded Plover Charadrius bicinctus | NT | non-breeding (2004–2005) | 600 birds | A4i |
| Sharp-tailed Sandpiper Calidris acuminata | VU | non-breeding (1999–2008) | 6,440 birds | A4i |
| Red-necked Stint Calidris ruficollis | NT | non-breeding (2000–2008) | 3,645–9,000 birds | A4i |
| Orange-bellied Parrot Neophema chrysogaster | CR | non-breeding (1990–2007) | 6 birds | A1, A3 |
