With a few exceptions, I find members of the Senecio genus hard to id (there are about 25 Senecio sps listed on the ACT Census list plus some subspecies and a hybrid). Even with inflorescence present, I find id hard and would usually collect a specimen for my botanist friend if I can. Anyhow, I wouldn't dare to make a suggestion from the photo of a leaf.. The suggested species S prenanthoides is not on our Flora list; so if you are not 100% sure I would prefer to not include it in our current 2022 Flora list update. Perhaps better to revisit the site and collect a specimen? My botanist friend suggests digging out because roots can be important for id as well.
It is a perhaps a little rich coming from me, but I do think that most of the local Senecio sp are distinctive enough to be identifed from leaves alone. So having said that I am pretty much 100% sure of the ID and know this species well, the deep purple colouration of the leaf underside is distinctive. Including this species in the flora list for Mt Majura is up to you, it is common throughout the reserve if you know where to look (and is quite common throughout the ACT as well), so you will be able to collect a specimen should you need to. I also know that Senecio minimus occurs on Mt Majura (verifiable image records from a friend of mine submitted through inat), there is probably also Senecio phelleus.
Okay thanks so much for the information Tapirlord. I think since I miss id-ed S. bathurstianus as S hispidulus I try to avoid the genus (except S madagascariensis and S quadridentatus which are easy enough for me... ).
Even young S. quadridentatus can be quite purple on the backs of the leaves - quite a range in colour in the hundreds I pulled out of our garden, all from one plant which seeded last summer.
