Vault #7: Colonial Bureaucracy
Exactly how much gold was stored in the Old Treasury's gold vaults is not known. By the late 1860s annual gold discoveries were greatly reduced as the gold rushes lost momentum. Large companies financed deep lead-mining and quartz mining and the day of the 'lucky digger', who panned and sluiced for nuggets was over.
Instead, Old Treasury's gold vaults were used to store public service files and registers that recorded the statistics of the now prosperous colony of Victoria.
