“Asking for a friend” - Uninsured not-at-fault Crash

[Citroënbender]

My E46 piloting mate, got cleaned up mid-roundabout by someone entering without looking.

1. He’s an idiot for being uninsured. I’m personally quite annoyed, as I’d leaned on the goodwill of members here to source NOS/OEM parts for the car, which is almost certainly a financial write-off.

2. Is there a well-worn path for legal representation to assist someone in this position, to recover some of their loss (noting the event is in NSW)?

Any useful pointers would be appreciated. I feel like a shepherd to the lunatic fringe this last fortnight.
