The link below gives the CASA's FOI figures (among many others) reported to the AG's office. Interestingly, the latest report that comes up is 09/10. It's about this time the 12/13 report should almost be on the A.G's desk. Almost 3 years of figures not available. That's almost a term in office. If you know who is submitting FOI's you should compare that with what is reported in the near future. I do wonder if all FOI request's do get reported?
