The best book I have read on this is by a lawyer named Joseph Klest called The Whole Truth. He’s an agnostic out in Chicago who has prosecuted around 500 sex abuse cases against the Church and has really good understanding of the institutional forces that create an environment for predators to seek prey (the same everywhere in the world, which is why this happens everywhere in the Church).
Australian Church: there’s a way out of this nightmare. The first thing you need to do is face the fact that you really have a problem. Happily, we belong to a tradition that has a big place for acts of contrition. Start there.
