The thing about JQ domestic is that it makes some kind of sense, in a limited form. At its current size it is clearly cannibalising the core business though. As a going concern i am sure that now that the start-up costs have all been swallowed it might be a saleable asset.
I don't speak to many people (any, actually) that aspire to fly on JQ a second time. Eventually they will run out of punters. You cannot gouge travellers forever with added punitive charges. But the whole business model seems to be based on that strategy. It might just be at or near its peak value now.
