Philydrum lanuginosum (ID by Mr TonyFromSydney), the perversely-named woolly water-lily. Lake Mitchell (Quaid's Dam or Southedge Dam), between Mt Molloy and Mareeba, W of Cairns, Queensland, Australia.
Look! I've been linked to on Wikipedia :-)
Click here to see where this photo was taken, looking south-west (the Google pic was obviously done when the lake was pretty dried out).
