The parish is located on the lower North Shore of Sydney and has two ministry centres in Cammeray and Naremburn.

The Church's vision is that "By God’s grace, we seek to see lives saved through knowing Christ".

By 1997, two of the churches had been disposed of,[clarification needed] the three halls had been demolished, the two rectories had been sold, and a new one had been built on site.

A church plant from St Thomas North Sydney led by Rick Smith resulted in the attendance and congregation size reversing quite radically, and by 2013 NCA had nine congregations and a normal Sunday attendance of over 600.

An article appeared in the May 2009 issue of Southern Cross, the magazine of the Anglican Diocese of Sydney, profiling the SJEC ministry.
