Based on beaks guessing looks more like Aust Raven rather than Little Raven. Were busily feeding on something (?) in roadside nature strip and pulling up quite of the groundcover veg and doing a lot of bioturbation in the process. Looked like a mix of adult and immature birds.
In my experience most of the ravens round bungendore are littles. Hackles look quite short (supportive of Little Raven). Generally Australian ravens tend to occur in smaller numbers (2s,3s etc), and Little Ravens tend to forage in larger groups. Easiest way to tell the two apart is by call.
