After a five-year career as a high-school teacher, Croucher began training in 1964 for the
Baptist ministry in New South Wales. He worked for the InterVarsity Fellowship (1968–1970) (now the
Australian Fellowship of Evangelical Students (AFES)); then pastored churches in Australia: Narwee and Central Baptist Church - both in Sydney - and
Blackburn Baptist Church in Melbourne, which became a "megachurch" in the late 1970s, with seven pastors, a salaried staff of 25 and 1,000 attending; plus several interim ministries. He was then, briefly, pastor at First Baptist Church,
Vancouver,
Canada. From 1983 to 1991 he worked for
World Vision Australia. Since 1991, Croucher has been founding director of John Mark Ministries, serving pastors, ex-pastors, church leaders and their spouses throughout Australia and elsewhere.Les Scarborough (NSW, now retired) and Psychologist/Trainer Tim Dyer (Tasmania and elsewhere) are colleagues. The John Mark Ministries website, with 20,000+ articles, claims to be one of the most accessed non-denominational religious websites in Australia. In 2011, Croucher added his voice to those of other Christian leaders calling for the introduction of
same-sex marriage in Australia. ==Books==
