Respect is two-way street: Morrison

Treasurer Scott Morrison believes the one rule for migrants to Australia is "you come to join us, not change us".

In the wake of the fatal shooting involving 15-year-old Farhad Khalil Mohammad Jabar, Muslim leaders have urged their communities against extremist actions.

Mr Morrison defended the nation's selective immigration programs in an interview with 5AA radio in Adelaide on Friday, saying those entering should respect Australians and that respect should be returned.
