Roger Shuff's Searching for the True Church: Brethren and Evangelicals in Mid-Twentieth-Century England (Paternoster, 2005)

Argues that Brethren decline since WW2 attributable to a policy of introspection amid rapid social change, resurgence of pandenominational evangelicalism, nonrealisation of an imminent parousia, and a tradition of local church autonomy.

I would add, re Australia, a lack of healthy leadership culture and insufficient leadership development; and a tendency for nepotism, cronyism and other forms of corruption that cause good people to leave.
