I had a similar roo incident in one of my LH Torana's with almost the same damage and while I was devastated at the time, it really wasn't too bad to fix.
The grille is obviously stuffed, but the nosecone is a pretty easy fix if you just take your time. Looks like the bonnet and bumper are OK too.

Bloody 'roos are a constant problem down my way, I hate driving at dawn or dusk when they feed by the roads edge.

You'll be OK fixing this one, just take your time....
