High above Lobster Beach is this small aboriginal rock engraving site that has a beautiful view across the Hawkesbury River.
These are three inscribed circles. The round shape in the middle is where some of the rock has broken away.
This may represent the moon or perhaps a boomerang.
Two very nicely decorated shields.
This is a little fish but it could possibly be a fake. The grooves are cut with a sharp V shaped cross section, probably made using a metal chisel.
