Notes

  • S1327 - 344 estimates 25,000 - 1,000,000, for Australian population. Proportion of population in New Guinea assumed to be relatively small.
  • S6788 - Estimate more conservative than for WPE4; based on data from 1980s from major floodplain region in far N Australia, which is largely intact, as well as consideration of status and overall extent of habitat.
  • T4269 - No information on trend.
