The Rev Chris Edwards was the founding minister of Holy Trinity Adelaide Hills, in South Australia, which grew more than tenfold under his leadership. He later led St Paul's Anglican Church, Tervuren, Belgium and was chairman of its school.
He is 52 years old.
Since returning to Australia, Mr Edwards has been the Mission Director of Anglican Retirement Villages, ARV, in Sydney.
Mr Edwards worked as a marketing executive in the finance and banking sector before studying at Moore Theological College and entering the ministry in 1994 as curate at St George's Church, Engadine.
The post became vacant when Dr Davies, who had been the Bishop of North Sydney since 2001, was elected Archbishop of Australia's largest Anglican diocese in August.
The Northern Region contains 64 parishes, including some of the largest churches in Sydney and emerging multicultural ministries.
"Chris is a proven leader, a very effective minister of God's word, and a faithful and committed pastor. This is an exciting time for outreach in the Northern Region with the good news of Jesus." Archbishop Davies said.
The Standing Committee of the Diocese overwhelmingly endorsed the nomination of Mr Edwards at its meeting on Monday 11th November, 2013.
Mr Edwards will be consecrated Bishop in St Andrew's Cathedral next May.
