Discovery Bay near Portland Vic.
It would have been nice to get all three blade sets symmetrical. Love the curve in those big aerofoils.
"On the south-western coast is an area where columnar and branching calcrete structures over 1 m high have formed from enlargement and subsequent infilling of hollows and pipes in the dune limestone. These have the appearance of a “petrified forest” although they are properly called rhizo-concretions and are not actually fossils."
