The Orange Order was never as prominent in the Australian colonies as its own publicity asserted and its arguments against the power of Rome in Australian politics and society were more shrill than accurate. However, it held a clearly defined position as a vector of anti-Catholicism and ultra-Protestantism in many parts of colonial Australia, and its parades and social gatherings were important spaces for the formation of Australian Protestant identities imbued with varying levels of Irishness. The use of public space meant that the Loyal Orange Institution had a wider impact than their often small numbers might otherwise suggest.With their parades, sermons, public meetings, and demonstrations many Orangemen and women attempted to claim colonial public space not only as Protestant, but as a particularly Irish inflected anti-Catholicism.
