"Invasion Day" is a term used by many Indigenous Australians to refer to January 26, the date when the British First Fleet arrived in 1788. This event marked the beginning of British colonization in Australia, which had significant and often devastating impacts on Indigenous communities, cultures, and lands. Many Australians observe January 26 as a day of mourning and reflection, highlighting the ongoing struggles faced by Indigenous peoples. Events and protests are held across the country to raise awareness about the historical injustices and to advocate for reconciliation and recognition of Indigenous rights, including discussions around changing the date of the national holiday.
