for vegetation on dunes, I've never seen anything but sparse long grass or brightish green ground cover vine type stuff(not a gardener, you can tell cant you)
I studied the dune ecosystem in highschool, and the scrubby grass is 'spinifex' but the distance away from the railway means I'll likely impair performance but putting down thousands of grass objects. I'll likely put down some scrubby trees and bushes for effect, and leave it at that.
Colhad, cheers for that mate, I had a look, and I see the ones you mean .
Anyone know if there is any NSW Surf Lifesaving stuff out there, i'm mostly interested in the red/yellow flags, or some kind of beach "HQ" for them (usually called a surf lifesaving club?)
