Welcome to Mangrove Mountain Union Church


Cnr. Bloodtree Rd & Wisemans Ferry Rd
Mangrove Mountain
N.S.W., 2250. AUSTRALIA.

About Us

Gavin McGrath is a religiously conservative Protestant Christian of a Reformed (Low Church Evangelical) Anglican background who upholds the Received Text and King James Bible of 1611. From April 2020, Gavin is a retired school teacher of both New South Wales, Australia, and London, UK. He is a lay preacher who sometimes preaches at Mangrove Mountain Union Church, established in 1912, which is just north of Sydney, near Gosford. Union Churches are part of the historic church fabric of New South Wales and Australia. Mangrove Mountain Union Church is a typical Australian Union Church in that it is independently owned and autonomously administered. This particular Union Church requires that those renting it out subscribe to the Nicene Creed. It is hired out by multiple persons and groups, some of whom are denominationally affiliated and some of whom are not. Like other Union Churches in Australia, a person or group renting out this church at a given point in time, is independent from, and has no connection with, any other person or group using the Church at any other time.
