Thank you Karen Weaving & Danilo Lüdke for confirming the id of this species for us

General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Adults ~18mm. Males & females are separated by the shape of their rear end. They seem to be the same size.
Neagenors are highlighted by heavy shoulder spines.
Note the unusual black tip to the scutellum here; typically it's pale or the same colour as the body in other Pentatomids. Also note how it's curled up; typically being flat or slightly raised. Danilo noted this as "the reflexed tip of the scutellum".
We can't be sure the nymph is the same species as the adults. However, we have only found one 1 adult Neagenor species here so far, and think it's a reasonable assumption it is the same species.
We think we have photographed 4 specimens in Jan (M), Feb (M), Mar (F) & Oct (Nymph)
