There are two main groups - those with ‘petals’ and those, like this one, without. For those without ‘petals’ like this one, the Vicflora key says to examine the seeds, count the number of green leaf like bracts closely pressed round the flower heads, measure the width of the flower heads, look at the general shape if the leaves and the shape of the leaf lobes, if any,, and how the leaves are arranged. Etc.
Not something one can tell from a photo. With common local species, the moderators can ID some from sight with good clear photos.

There are at lot of Senecios and they are not an easy group, a few useful references are: Thompson, I.R. (2004). Taxonomic studies of Australian Senecio (Asteraceae): 1. The disciform species. Muelleria 19, 101–214; Thompson, I.R. (2004). Taxonomic studies of Australian Senecio (Asteraceae): 2. The shrubby, discoid species and the allied radiate species Senecio linearifolius, Muelleria 20: 67–110. Thompson, I.R. (2006) Taxonomic Studies of Australian Senecio (Asteraceae): 3. Radiate, arid region species allied to S. magnificus and the radiate, alpine species S. pectinatus, Muelleria 20: 111–138. Thompson, I.R. (2005) Taxonomic studies of Australian Senecio (Asteraceae): 5. The S. pinnatifolius / S. lautus complex, Muelleria 21: 23–76. These papers contain images of the species and distribution maps, I don't think No 4 deals with any local species. A further paper that deals with the group is:
A taxonomic treatment of tribe Senecioneae (Asteraceae) in Australia, Muelleria 24: 51–110. These papers are available from https://www.rbg.vic.gov.au/science/publications/muelleria/muelleria-online
