Prominent human rights organisation Liberty Victoria has thrown out a challenge to an inquiry set up by Prime Minister Malcolm Turnbull.

In the wake of the overwhelming vote in favour of marriage equality, Mr Turnbull ordered a review to see whether Australian law "adequately protects" the human right to freedom of religion.

Liberty Victoria has turned this on its head by telling the inquiry that religious privileges are far too extensive and must be rolled back.

Liberty Victoria labelled the opposition’s proposed plan to allow concerned parents access to photographs and other details of sex offenders "an unnecessary and costly scheme that would have no impact on the rates of sexual offences in Victoria."  

Liberty Victoria President Jessie Taylor dismissed the proposal as “an irrational and expensive attempt to make political gain out of a highly emotive issue without reference to any available evidence.”

The breathtaking simplicity and callousness of the recently resuscitated Deputy Prime Minister lays bare the attempt to use human lives for votes, Liberty Victoria said today.

“Barnaby Joyce bounces back into Parliament saying control borders or lose votes," said Jessie Taylor, President of the human rights group. “Forget compassion, disregard any duty to one’s fellow human beings, focus on the votes, that is the message.

Australia’s name for decency and a fair go has been permanently stained by the latest sickening violence on Manus Island, Liberty Victoria said today.

Reports of attacks on refugees with metal poles and other weapons to force them to a new unfinished prison after three weeks of resistance shames the nation, said Liberty president Jessie Taylor.

“Our leaders seem deaf to the appeals by Australians of the Year, religious leaders and people going into the street,” she said.
