NCLS Research is a joint venture started by church mission agencies in the early 1990s. Our research areas include studying Australian spirituality, church health, effective and sustainable leadership, and the connections between church and community. The most well known five-yearly project is called the National Church Life Survey, which has had millions of participants. Co-operating denominations, including Catholics, Anglicans and Protestants, are a network for sharing practical resources to help churches and communities.
