Brisbane tuff

[5] Brisbane tuff began to be used during the period when Captain Patrick Logan was the commandant of the Moreton Bay penal colony.

Brisbane tuff was formed by the welding and compaction of volcanic ash more than 226 million years ago.

Duhig obtained a licence from America and opened the Benedict Stone works at Bowen Hills on 9 August 1929.

In February 1930 Colonial Mutual Life (CML) advanced Duhig a £70,000 mortgage on his properties which included the stone works.

CML used Benedict stone to build a number of their Australian offices, ensuring some of their mortgage was repaid and employed Hennessey and Concrete Constructions (Qld) Ltd, Brisbane (Duhig's architect and contractor for the Holy Name Cathedral).
