Others who have worked in a similar area to me in Australia.
NCLS Research, Sydney. Their main gig is the National Church Life Survey in census years. Lots of research papers available.
Christian Research Association, Melbourne.
McCrindle Research, Sydney. Surveys to infographics.
Deep White. Aaron MacAleese is a data scientist in Melbourne. He's done some similar stuff to me (in a more timely manner).
Anyone else? I'd love to know about them.
