Yes, the WTS could do a number of ploys to get out of it.
Farkle Defense: "Did I do that?" http://www.youtube.com/watch?v=ClnSMCdw6E8 Followed by a quick public apology, payments, and compliance with the law.
Take it to the Limit Defense: Take the case all the way to the highest court is Austrailia and beyond (UN Court) arguing all the way that the law is overly broad and impinges on the freedom of the religion to preach. Friends of the Court brief to be filed by the Roman Catholic, Mormans, Baptists, etc. church. Wouldn't that be funny, JWs in a UN court with False Religions. JWs will come out the hero.
Now You See Them, Now You Don't Defense: Declare Victoria Australia to be Satan's land and leave the area (or go underground).

In all serious, Mr. Unthank has raised public awareness on this issue and Austalia is witnesses the Jehovah's Witness church being a slippery snake. This is going to turn thousands off from the cult. For that alone, he is a success.
