Political and community leaders have told those who don't like the Australia's way of life to leave, as protests over the killing of a NSW police accountant and counter demonstrations began.
A vocal bunch of about 20 people rallied outside the Parramatta mosque last night, the place where Farhad Khalil Mohammad Jabar prayed before gunning down the 58-year-old a week earlier.
A larger counter demonstration also formed about 100 metres away with about 75 police officers keeping the groups separated.
No arrests were made and for several hours the protesters yelled their provocative slogans at each other.
Earlier yesterday, Prime Minister Malcolm Turnbull called on all Australians to adopt a code of "mutual respect".
Mr Turnbull has also organised an urgent meeting of security chiefs to discuss further measures to counter the spread of violent extremism and said it was not "compulsory to live in Australia".
"If you find Australian values unpalatable, then there's a big wide world out there and people have got freedom of movement," he said.
The Grand Mufti of Australia, Ibrahim Abu Mohamed, chose to speak to media instead of meeting with Mr Turnbull.
While telling those with radical views to "stop messing with Australia and its society", he did not describe Mr Cheng's murder as terrorism.
"Sadly, a very, very small number of Australians of Muslim faith have chosen this path," he told reporters through an interpreter.
Authorities are still trying to discover how Jabar got the .38 calibre revolver used to murder Mr Cheng and how he was prompted to commit the killing.
Three of four males arrested in Wednesday's dawn raids have since been released but an 18-year-old man remains in custody without charge after investigators applied for a court order extending his stay behind bars.
More than 400 police officers will be stationed across the regional Victorian city of Bendigo on Saturday, where a large protest against the construction of a mosque is expected.
