Irish Immigration to Australia

Believe it or not, Australia is perhaps the most “Irish” nation in the world — next to Ireland, of course.

Apart from the Scots, the Irish have been a major part of Australia’s demographic, ethnic, and cultural evolution since the arrival of the First Fleet. According to the 2021 census of cultural diversity in Australia, 9.5% of the people were of Irish ancestry — forming the third largest ethnic group in Australia behind the English and Australians.

It’s thus safe to say that the Irish are a crucial part of Australia’s culture and history. But how did the Irish come to Australia? And how has Irish immigration evolved since the First Fleet?

Let’s take a look.

History of the Irish in Australia

Irish immigrants or Irish Australians are inhabitants of Australia that are of Irish descent. They may be direct immigrants or descendants of Irish immigrants.

Initially, Irish citizens came to Australia as convicts around the time the First Fleet arrived in New South Wales in 1788. The first record of the Irish coming to Australia is from 1791, when 155 Irish convicts were shipped to Sydney.

Others came to escape the Irish famine and the struggles in the following years. Many also came to reunite with their family as convicts were transported without any means of support or family.

Australia experienced a surge in Irish immigrants between the late 18th century and the late 19th century, by the end, Irish immigrants constituted around ⅓ rd of Australia’s population.

Irish immigrants played a significant role in shaping Australia, given their large population over the years. Australia also has the highest number of Irish descendants after Ireland. Their immigration thus led to cultural, political, and economic changes in Australia.

Present-Day Census
