Prime Minister Scott Morrison and his family have gathered at a Coptic church in southern Sydney to pray with the Arabic community after the Christchurch massacre.
Mr Morrison arrived at St Mark Coptic Church in Arncliffe in southern Sydney with his wife and two daughters on Sunday morning.
He was joined by Immigration Minister David Coleman to pray for the victims of Friday's massacre.
Fifty people died in the attack on two mosques on New Zealand's South Island and about 40 people are in hospital.
The prime minister will later join politicians and religious figures including the Grand Mufti of Australia at St Mary's Cathedral in Sydney for an interfaith prayer for the victims.
Members of the public "from any denomination" have been invited to pray alongside Mr Morrison, Grand Mufti Dr Ibrahim Abu Mohammed, NSW Premier Gladys Berejiklian, the New Zealand Consul General to Australia Bill Dobbie and others.
The gathering will take place at 3.30pm on Sunday at St Mary's Cathedral.
Nearby, a rally to show solidarity for the Muslim community is expected to draw a large crowd.
Greens Senator Mehreen Faruqi, along with a number of activists, are set to make speeches at a rally outside the New Zealand consulate on Sunday afternoon.
