This plant is obviously a member of the Asteraceae, but I can't find
it in my book on Australian weeds. I don't think it is a native.

It grows in fairly dense stands under Casuarina trees on the flood
plain of a river in a warm temperate area of inland NSW (Bathurst). It
is just coming into flower now (mid summer).

Associated plants are Hemlock and Bidens (Cobbler's Pegs).

Apologies for the rather inadequate picture of the composite flower.

Thanks Kauhl and Peter. Bidens subalternans it certainly is. To judge
by the description, I would not care to push through the stands when
they are seeding.
