Expert advice from @jackiemiles:
To choose between Craspedia variabilis or C.canens, it is important to look at the leaf hairs to see if they are woolly or not ("long fine loose silvery hairs" in the key branch leading to C.canens in NSW Flora). These leaves look grey enough to perhaps have those, but the photo resolution isn't good enough to tell.

Advice from @jackiemiles: According to iNaturalist South Africa, even in its area of origin, Dimorphotheca plants are often hybrids. And unlike Gazania, where the hybrids have been given a name (Gazania x splendens) there is no accepted name for Dimorphotheca hybrids, so best just left at genus, and not Dimorphotheca ecklonis or D.fruiticosa.

The National Herbarium census of plant taxa in the ACT (link below) can help you determine if the plant you are observing is naturalised, or a local native. If your observation is a cultivated plant that has not naturalised then you should ensure the iNaturalistAU observation is marked as cultivated or not wild. Cultivated plants that are not naturalised may not be on the census list.

If the observation is confirmed as research grade and the species is not on the plant census, and it is growing wild (naturalised), then notify @actbiosecurity , as they will need to make a collection of the plant for the Herbarium botanists. The botanists will need to confirm the identification and if confirmed, give the plant material an accession number. The accession number can then be added in the comments or notes field for the observation.

This key from the NSW Herbarium shows that close up photos of the leaf upper and lower surfaces and the width of the leaf is important for correct id of firethorns:

The main invasive blackberry species in SE Australia have been lumped together under a new scientific name, Rubus grabowskii
https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:737099-1
This includes species that were formally difficult to seperate with photos alone:
Rubus fruticosus subspecies
Rubus fruticosus varieties
Rubus anglocandicans

Hakea decurrens and Hakea sericea are look-a-likes that are often misidentified. Arthur Chapman @arthur_chapman has provided a very useful guide to their identification: https://drive.google.com/file/d/1367CE1j6kS6J4Obqsr5fDdgz2yW9-xgA/view?usp=drivesdk
