[1] The first traces of Bulgarian emigration to Australia date back to 1876, when an unknown number of Bulgarians fleeing the Ottoman atrocities in the wake of the April Uprising settled in Queensland and Tasmania.
[2] Following the anti-Ottoman Ilinden–Preobrazhenie Uprising of 1908, around 100 Bulgarians from Macedonia and southern Thrace emigrated to Australia.
[4] The first larger organized group of Bulgarian emigrants arrived in Australia in 1907 and consisted of around 100 people, most from the Veliko Tarnovo region; 30 of these disembarked in Adelaide, South Australia, 35 in Melbourne, Victoria and 35 in Sydney, New South Wales.
[5] After the end of World War II, there was an influx of hundreds of Bulgarian political emigrants who did not accept the newly established communist authority in Bulgaria.
It is difficult to establish the exact number of Bulgarian settlers in the pre-World War II period, but one estimate puts the number of emigrants from the Kingdom of Bulgaria at 1,000, with another 5,000 to 6,000 ethnic Bulgarian emigrants from Macedonia, Dobruja and Bessarabia.
