Hi Brad – there is a case Trustees of the Marist Brothers vs Byron Shire Council dated 30 August 1984 which contains some useful information. The case involves a Holiday Home which was used by the Marist brothers for rest and recreation and the Court found that the Holiday Home was exempt under the old Act. I have a copy of the case if you can’t find it on-line.
We have had similar cases (but not identical) where active Marist Brothers live in residences and have gained exemptions with us based on the case law above.
Hope this assists.
Mick
