Sounds like the "heckler's veto" is triumphant down in Australia. We've been battling it here in California regarding "illegal immigration" forums. So far we've been winning. However, the city of Carlsbad (CA) is now asking Sen. Bill Morrow for $100,000 to cover the costs incurred to maintain security at the forum he finally was able to hold.
It's outrageous!!!
I'm pleased to say most places in Australia still have police who are willing to enforce the law.
