Perennial Eragrostis sp. in primarily native pasture (formely NTG) tentatively identified as E. leptostachya using the S.W.L Jacobs key. Posting to NatureMapr as I am still not entirely certain of this ID due to lack conspicous of key field characteristics (i.e. yellow banding, glands below spikelets) and I am not particularly well versed in Eragrostis ID. Final two images depict a spikelet stem and the remains of the ligule and hairs (very dessicated sorry!).
If it doesn't have the yellow glands (obvious when fresh) then not leptostachya. Also spikelets tend to diverge nearly at 90 degrees in that species. brownii is polymorphic, varying from nearly spike-like to open branched (the latter used to be called E benthamii).

Amazing! Thank you for your well thought out response. I have often relied on the inflorescence of brownii being quite contracted to split it from the other native Eragrostis - looks like I will need to rethink this one!
