Currently the Trinity Network consists of 5 centres; Trinity City, Trinity Hills, Trinity Mount Barker, Trinity North East and Trinity Bay.

Trinity City was established in 1836 with the arrival of HMS Buffalo and the founding of South Australia. Trinity City has 5 gatherings each Sunday on site and in the cinema located next to the property.

Trinity Hills was established in February 2001 as a plant from Trinity City.  Trinity Hills now has 2 congregations meeting each Sunday; 10 AM and 5 PM.

Trinity Mount Barker was established in February 2010 as a plant from Trinity Hills. Trinity Mount Barker meets Sunday mornings at 10AM at the Littlehampton Primary School.

Trinity North East was established in February 2010 as a plant from Trinity City. Trinity North East meets in the Modbury Hospital Education Centre Auditorium.

We aim, under God, to expand the Trinity Network as new Bible-teaching churches are planted across Adelaide and further afield.
