    Re: Flinders' Survey of Australia.

    As an illustrative example of how the 'top end' (or parts of the northern, tropical region of Australia) are "particularly isolated and barely inhabited", how often these days is a new mammal about as large as a human discovered?

    "The Australian Snubfin Dolphin (Orcaella heinsohni) is a recently recognised species of dolphin, scientifically described in 2005."

    I learned about this recently thanks to a segment on a TV science show
    http://www.abc.net.au/catalyst/       (
    Kakadu Dolphins)
    that showed how research into this species and another, the Indo-Pacific Humpback Dolphin, is being conducted in the South Alligator River, which itself must be fairly unique as a large (tidal for 100 kilometres upstream) river system contained within and draining a national park - the one featured in Crocodile Dundee (movie).

    Map here:

    However, the South Alligator is visited by thousands of tourists every year, and shouldn't be confused with the much less well-known and less visited area well to its west.

    Also thanks to the marvels of Google, here is a map of this '
    complicated coast with many off-shore islands and reefs':

    Using the tools at top left this map/satellite photo can be zoomed into, to quite a remarkable extent (scale is at bottom left).  I imagine that these images would make a very useful adjunct to the best nautical charts available of this area, if visited by boat.
