User's notes
Looks like the non-native, Cyperus eragrostis (umbrella sedge). Due to dense spikelet clusters – a bit umbel like, and very prominent and long inflorescence bracts. The spikelets should be laterally compressed as well.
Common in disturbed drainage lines, and around urban ponds.
The question: it's growing in M t Pleasant Reserve. Should we spray it out?

It is a persistent weed and one you would want to remove from locations where there is a reasonable cover of native species, or a significant environment down stream. However as it tends to grow in or near creeks use of foliar spray (glysophate) can be tricky and you will need to read the label booklet re use near waterways. If clumps are isolated I have had some success with the mattock.

A bit too much to mattock. Spraying might be an option - there's not flowing water near the infestation.
We'd be looking at spray + mulch + revegetation, and extending an area of revegetation where we've been working on a large patch of vinca, now largely eradicated... All done with Parks and Conservation advice and assistance, and with funding through an Environment ACT grant.
