- S3914 - 344: Estimate in Australia 100,000 - 1,000,000, trend FLU, but available information suggests that population towards lower end of range, and that 100,000 - 1,000,000, also appropriate for entire population. "Locally common New Guinea"; scarce Java (180). 289: Large numbers  estimated southern New Guinea but not known if were migrants from Australia.
- S7743 - Estimate based on numbers in colonies and consideration of survey difficulties and numbers outside Australia.
- T5674 - Trend is fluctuating; possible long-term decline due to loss of some breeding habitat in E Australia requires confirmation.
