I have a photograph - at risk of this being splashed all over Carsguide.com.au
The shelf itself is thin and flimsy, I am guessing plastic covered in light material, and seems to be molded, you can see where the little flap/door whatever it is called is situation, they seem to have shaped the shelf down to incorporate the metal hook.
I am going to guess that rather than cut a new hole this is a replacement shelf. Which shouldn't be difficult one would think, and they are lightweight and easy to ship. Surely something that can be sent over in the hold of a plane?
Or actually, maybe they can just cut a new hole for ones in country, it may not be pretty but it doesn't have to be. There is no law about having to have neat pretty holes in the rear shelf.

Seems an easy fix but I guess we wait and see. You haven’t heard anything about a recall on your car yet? @Murphster
