I don't have any notes for you but maybe some thoughts to get you started... if that's OK.
Low Catholic, Anglican & Presbyterian attendance now and a relatively large switch out.
Large Uniting Attendance and quite a high switch. But more in than out.
Huge Pentecostal attendance and yet a large switch. But more in than out.
Baptist is almost equal in and out.
The thing to do would be to understand the relative approaches each denomiantion has to Christianity.
Catholics and Anglicans tend to be quite traditional in their worship approach on the whole (but Anglican is trying to address this).
Uniting tend to focus more on the social impact of Christianity (IMHO)
Pentecostal is exciting and modern and out there.
Baptist, I'm not sure, but I would say probably a more modern approach.
Around the world, growing churches tend to be those that are sticking close to the word of God and not going out on a limb in their interpretations. You could probably check that statistic, but I am thinking particularly of the African churches in the Anglican communion you are rejecting the US Episcopalean interpretation of scripture and breaking from the Anglican communion AND YET they are growing.
Could it be that people are looking for modern approaches that are more exciting but maybe find them lacking in something and then move away? I can't say for sure, just throwing things out there and happy for people to disagree.
The move from the Presbyterian church could well be due to the fact that the Methodist and Presbyterian churches merged some time ago to be Uniting. Some churches stayed Presbyterian while others merged. So people may have grown up Pressie but then became Uniting.
Anglicans could be leaving because they either do or don't agree with letting women and homosexuals into higher positions in the church (depending on whether the stats are from Sydney or Australia-wide).
Anyway, there's some thoughts. Hope it helps.
