hi ant
i can see the problem, this website mentions several grasses that look
like serrated tussock, see the heading "look alikes"
http://www.esc.nsw.gov.au/Weeds/Shee...%20tussock.htm
and this one points out how similar poa is to serrated tussock:

but i've learned a lot about grass weeds just because you asked!
