Wow! That's hitting them where it really hurts - in the pocketbook.
Wonder how the WTS will respond?
For anything else, there would be trumpeting calls for action on JW.Borg - write letters to the Australian government! Special tract campaign! Satanic persecution!
But if they advertise this on their website, it would be really hard to do without mentioning, why, exactly, it's happening. And "we are losing our tax exemption because we hid child molesters" won't exactly play well, even for die-hard JWs.
And if they do mention it, but don't express the reason why, I would think that would only steel the resolve of the government to carry out its plan.
WTS is screwed - cornered, with no easy way out.
Oh, I guess I could mention, there is an extraordinarily easy way out - change its child abuse policies to something approaching "worldly" (higher) standards. But of course that's not really an option for them, is it? They'd have to admit they had been wrong, which seems like it would open the door for massive lawsuits.
