OAC Ministries is a Christian organisation that reaches out to the community with messages of hope. Our aim is to serve local communities, churches and families through communicating Christian tenets, principles and values.


Our presentations always explain the core of the Christian faith, with practical implications.


We use visual methods, i.e. dramatic story-telling, multi-media, images, sketching, puppets, music, objects and more. These visual methods together with the presenters’ personalities, and the Spirit in which we operate, provide a unique presentation style that aims to draw and hold an audience.


God created all things. One God eternally exists in three persons: Father, Son and Holy Spirit.
The Bible was inspired by God to give people his message.
Fallen human nature is to turn away from God.
Jesus lived a perfect life, died to take the consequences of our rebellion against God so that we might live. He rose again, gives his Spirit to us in the present, and will visibly return.
God gives eternal life to those who trust in Christ, and re-turn to God.
This trust has practical implications for how we live.

We concur with the Lausanne Movement’s Cape Town Commitment, an agreed statement of global, mainstream Christians.


1892 An English Barrister, E.P. Field, preached to lunch-hour crowds in Martin Place, Sydney, Australia, and formed the NSW Prayer Band to support this growing ministry.

1913 The NSW Prayer Band was renamed the NSW Evangelistic Prayer Band.

1922 W Bradley changed the name to ‘Open Air Campaigners’. Gospel wagons were used to take the gospel message to people throughout NSW.

1939 OAC worked among the armed services during World War II.

1940 – 1950 The work extended to the states of Queensland, Victoria, South Australia and overseas, firstly to New Zealand. It was during this period that the typical sketch-board painting method became the ‘trademark’ of the work.

By 1970 OAC was well established in North America, Britain and Germany. During the 1970s residential ministry extended to the Netherlands and Italy, with openings being made in many other countries.

The 1980s saw definitive expansion beyond the traditional protestant homelands and the following decade saw the establishment of branches in the former Communist Block, Latin America and India. The WA branch also commenced in 1988.

1982 The Australian branches changed their name to “OAC Ministries,” reflecting their desire to present the message in more culturally attuned ways, and to work together with churches in Outreach And Church ministries.

1990’s Presentations in schools increased, as did Community Contact Weeks hosted by local churches. OAC presenters became sought after for camps and other outreach settings.

Currently there are branches operating in 5 Australian states and in some 30 countries around the world. OAC International unites these nations under a common covenant.
