I have a cockatiel (small cousin to the cockatoo) at home. The first thing I thought when I saw "Australia" was "oh god, cockatoos." Mine regularly severs USB and headphone cables with ease then spends hours stripping all the insulation off preventing any hope of repair. I can only imagine what the Australian flying bolt cutters could do.

Edit: to anyone contemplating a parrot who owns a laptop, you will come back into the room to find it completely stripped of all its keys. Parrots just really love forcibly disassembling things.
