Acaena novae-zelandiae
Or also commonly known as BIDGEE-WIDGEE,

and  http://web.apolloparkps.vic.edu.au/Content/grade_area/pegasus_2002_website/Science_Pegasus/Plant_Database/Acaena_novae_zealandiae.html


seems to be a native to your part of the world
bit it doesn’t seem to be considered a weed, in fact this PDF document
talks about
using Acaena novae-zelandiae as a replacement for weeds.

http://www.gavic.org.au/pdfs/coastbklt.pdf

As always, establishment of desirable plants to replace the space
previously occupied by weeds has
been a vital component to Breamlea’s success. The indigenous species
planted by the group as part
of their treatment program include Bidgee Widgee (Acaena
novae-zelandiae), indigenous Pi g f a c e
(Carpobrotus rossii) and various tussock grasses.


So given that information I doubt you will find a “weed killer”
specifically targeting that plant.

Here is an organic “weed” killer developed and sold in Auckland

and another site that may be of help

Hi Bonnie

I spent some time researching your earlier question but unfortunately
found no useful information on the net.
In fact, I found this comment:
"There has been very little information published on the use of
herbicides for controlling this plant, likely due to a lack of
economic importance. "

Sorry we haven't been able to help find what you wanted.

Yes how embarrassing for me not to do more research on other common
names

http://www.cdfa.ca.gov/phpps/docs/4500regulationtext.PDF

this document specifies biddy - biddy as a noxious weed

as well as here
http://www.oda.state.or.us/plant/weed_control/Weedlistsci.html

but there still does not seem to be any information on a specific
“weed killer” for this plant.
