Prime Minister Malcolm Turnbull has vehemently condemned last week’s shooting in Parramatta, describing it as an “act of terrorism” and a “brutal murder”.

Mr Turnbull’s comments have come one week after 15-year-old gunman Farhad Jabar shot and killed police accountant Curtis Cheng as he was leaving police headquarters in Sydney’s west.

“He was murdered in an act of terrorism by a 15-year-old boy, motivated we believe by extremist political and religious views,” Mr Turnbull said in Sydney.

He said the phenomenon of violent extremism needed to be confronted by all Australians and a culture of mutual respect should be fostered across the country.

The Prime Minister also warned that anyone preaching hatred or extremism is undermining the success of the nation.

“It is not compulsory to live in Australia, if you find Australian values are, you know, unpalatable, then there’s a big wide world out there and people have got freedom of movement,” he said.

“Those who seek to gnaw away at that social fabric are not part of the Australian dream, they are not advancing the interests of our great country.

“Australia, my friends, has the greatest future ahead of it.”

His comments come after Parramatta Mosque chairman Neil El-Kadomi Neil told worshippers on Friday: “If you don’t like Australia, leave”.

Opposition Leader Bill Shorten agreed with those comments earlier today, saying: “If you really hate Australia, well then you should go”.
