Expenditure on restoration totalled approximately 1.2 million dollars. No further work took place until 1990 when a detailed maintenance study was prepared by Partridge and Davies, architects. This study detailed a long term maintenance program addressing small scale works on a long term basis rather than large scale projects. Work has since been carried out by craftsmen and tradespeople on the basis of funds available. It is hoped a long term stonework program be developed over the next year which is urgently required.
