Dura niveus looks very similar. https://bie.ala.org.au/species/https://biodiversity.org.au/afd/taxa/a9511e6a-96b9-4fd0-a0fd-f041f9ce0dc6#gallery The Dura (genus) is recognozed by the AFD as is also D. niveus.
It is till doing it today. Have you asked "management" or plant/monocot moderators bout this? Aira is a genus of grass (Poaceae) called Hairgrass. ALA does not list Dura as a synonym for Aira as far as I can see. There are however a couple of moncots that have dura as a species - Sclerochloa dura (Hardgrass) is introduced grass found in Australia used for turf also - Lomandra multiflora subsp. dura - Stiff Iron-grass whose natural S.A. community is critically endangered. OR this has nothing to do with it.
