Actually, it appears more to be a monopolistic device to prevent competition from "upstart" Australian Halal certifiers, FD.   Something commonly used in all societies to create cartels.  Adam Smith warned about the dangers of such practices in "The Wealth of Nations", as it is not confined to Halal certification by a long shot.  Indeed, we can presently see something similar occurring in the Australian mining industry at the moment over Iron ore production.   

... to the extent that he will deny even a risk of the ill-gotten millions ending up in the hands of terrorists.

Halal certification in Australia is dominated by four big Islamic groups – one in Melbourne and three in Sydney. They are the Australian Federation of Islamic Councils, the unofficial peak body; the Halal Certification Authority Australia, the Supreme Islamic Council of Halal Meat in Australia and the Islamic Co-ordinating Council of Victoria.

Under Islamic law, the money the certifiers earn is supposed to cover costs and if there is any left it goes to the Muslim community organisations that the certifying company is aligned with – mosques, schools and welfare groups.

Those who control the certification rights can also fund imams and bring preachers to Australia. Sydney-based Australian Federation of Islamic Councils (AFIC) set up an Islamic school in Tarneit in Melbourne's west and an Islamic centre on Christmas Island for Malaysian Muslims, says chief executive officer Amjad Mahboob.

"The international halal market is huge," Mahboob says, "and Australia being a primary producer of food items means we are relied upon so it's very important the credibility of what we do is protected at all times."

Yet that credibility has sometimes been brittle. In 2003, a court case involving Shafiq Khan, an influential figure around Sydney's Supreme Islamic Council of Halal Meat in Australia, saw former supporters swear he had diverted without approval more than $1 million to charities, including his own Al-Faisal College, at the expense of constituent charities. Former Prime Minister John Howard opened the college in 2000. Mr Khan negotiated a settlement and agreed to return the money to the council.

In 2009, the Victorian Supreme Court found the Islamic Co-ordinating Council of Victoria (ICCV) had defamed a competitor in the lucrative halal trade, and ordered damages be paid.

Then in 2012 a Sydney Islamic school aligned to the Australian Federation of Islamic Councils was ordered to pay back $9m in NSW government funding after it was found money had been allegedly diverted to the federation the peak body for halal certification in Australia. "It is a matter that is before the court," said Mahboob. "We are disputing the [NSW] minister's findings."

This year, in a Federal Court trademark case it was revealed two Sydney kebab shops got free fake certificates from a wholesaler, which if they'd opted to buy them elsewhere would have cost $5000 each.

In Melbourne and Sydney, the certifying industry has begun to move away from predominantly Middle Eastern interests  towards businesspeople from Turkey and the Balkans.

An investigator familiar with the industry said it was a "highly competitive"  and "very incestuous" market. "It is riven with factions," he said.
