As you say. Cardinal Pell has an excellent record for being faithful to the Church and for ferreting out heretical bishops and priests. I really haven’t followed this recently, but I suspect that the bad clergy in the Australian Church have worked with the Catholic-haters in the Aussie government to “convict” him.
I’ll just say this “conviction” stinks ... smells like the courtroom was full of kangaroos.
Heck, Francis seized on that initial indictment of Pell, as Pell had just initiated an investigation of Bergoglio's shady Vatican finances. Francis promptly sent the Cardinal back to Australia to be tried by Francis' secular wolves.
