Yes, there are just too many Pell-protege bishops among the Australian hierarchy for any effectual change to happen anytime soon.
And the 2020 Plenary Council will be useless unless there is a good cross-section of the "laity" represented. That will be difficult given that already 85% of Australian Catholics no longer attend Mass regularly.
There are sunday masses where the number of people under 70 years old can be counted on one hand! The future of the Catholic Church in Australia looks bleak if the JPII bishops don't get their heads out of the sand.
