The figures for Australia are much harder to get because of their tax free exemption as a "charity". There is no public reporting of income and expenditure.
Need I remind people that churches across the world regularly say that the you are giving "for the Lord's work". Apparently the Lord's work mainly includes paying clergy and staff and upkeep on the building. You'd think the Lord (Jesus Christ Superstar) would have better things to work on such as feeding starving children in third world nations or giving us the cure for cancer. The Lord Jesus works in mysterious ways.
