- S5417 - 344: Highly mobile and irruptive behaviour make former division into two populations inappropriate. Population size probably near 1 million mark.
- S8076 - Estimated population size derived from the 2008 National Survey of Waterbirds, evidence from subsequent post-drought recovery, and peak estimates from sub-regions and key sites.
- T6083 - Trend is fluctuating with inland rainfall/flooding although some important breeding areas in E Australia have been lost or are less viable due to river regulation.
