The Aus company is a owned by the US company. Graet is the director of the Aus company and thus may well be in the same situation as the rest of us regarding the status of what Ukyo has done, however, as a director he may be held responsible for the actions of the Aus company ...
The share (just the one) is owned by Ukyo.
Here's the post from the 94% thread with the Australian doc:
In WeEx US there is only Ukyo as director, whereas in WeEx AUS there is Ukyo and Graet. Ukyo being the sole shareholder in both cases.
