Zooming in; this is the early morning photo; I knew I had to come back later to see those water-lilies opened up though.
.. and, three and a half hours later
a sediment-barrier fence in view
Stepping sideways a little now, away from the catchment and beyond the barrier fence. Following a pathway through the bushland; and a special find awaits!
Thanks to Don Herbison-Evans for identifying it for me; he wrote, "that is a female Papilio aegeus", see http://lepidoptera.butterflyhouse.com.au/papi/aegeus.html
I'll find it easier to remember the common-name: Orchard or Citrus Swallowtail Butterfly
