This is all that remains of the Bullock Point Jetty. It was built in the 1960's for a company that was sand mining on Fraser Island for the minerals Rutile and Zurcon. Sand mining on Fraser was stopped in the 1970's and the jetty was used only occasionally from then on. Finally it was deemed too dangerous and in 2010 the main jetty structure was removed.
Now, only the birds use the old posts. When I was out there the other day this Pied Cormorant was deciding where it wanted to perch.
Eventually it sat on a post right next to this female Australian Darter (Anhinga melanogaster).
The Cormorant proceeded to preen its feathers from every possible angle while the Darter looked on.
Then the Darter did some preening as well.
However, it really looked as if the last word was with the Cormorant!
