Flint, as in flint nodules found in chalk deposits in England is not common in Australia; but chert is very common (flint is a variety of chert).

Yes, but the blue mountains are a fair while away from where I am, and gravel beds are not as common as rocks in rivers.
Would you be able to find flint (easilyish) in New South Wales?
