The place of religion in Australia has never been more contested than it is today. In this new and timely essay, Frank Brennan and Michael Casey draw on the Catholic tradition to explain why freedom of religion remains of vital importance for the way of life enjoyed in a secular liberal democracy such as Australia. Greg Craven complements Brennan and Casey’s philosophical analysis with an essay discussing how freedom of religion is currently protected in Australia, and what reforms are necessary in order to ensure its protection in the decades ahead.
