There are a lot of species not yet included in the Plantnet key. It might be one of those. https://apps.lucidcentral.org/plants_se_nsw/text/entities/solanum_stelligerum.htm This is a late draft. The final could be a bit different.
At the Milton R Landcare Nursery we've pondered over this local Solanum many times. Seems to have paler and duller leaf than shown in references available.
