This book traces the history of the Queensland Irish Association, one of the most successful ethnic organisations in Australia. Founded in 1898, it reacted against the divisive religious history of Ireland, enshrining denominational tolerance as a foundational principle. It was an engine of integration, melding evolving Irishness with primary loyalty to Australia. Remarkably resilient, it navigated wars, rebellion in Ireland, economic upheavals, and internal disruptions. The QIA celebrates its 125th anniversary in 2023, continuing as the chief custodian of Irish heritage and culture in Queensland. The makers of this history were past and present QIA members and officials. Sources included Association records and a rich heritage collection, photographs, and reminiscences.
