It can sometimes also refer to the Scandinavian Peninsula. In English usage, Scandinavia is sometimes used as a synonym for Nordic countries.

While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities.

Ethiopian Australians are immigrants from Ethiopia to Australia and their descendants. However, as Ethiopia is a multi-ethnic country with significant inter-ethnic tensions, not all individuals from Ethiopia accept the label "Ethiopian", instead preferring to identify by their ethnic group. In particular, various Oromo people use the term 'Oromo Australian' instead. In contrast, there are many individuals who prefer to label themselves as Ethiopian Australians. This is because they oppose labelling themselves based on their ethnicity as they see it as divisive and politicising their ethnic identity. This is common among the Amharic-speaking community along with ethnically mixed individuals, compared to others who stand by their ethnic identity.
European Australians are citizens or residents of Australia whose ancestry originates from the peoples of Europe. They form the largest panethnic group in the country.

It is impossible to quantify the precise proportion of the population with European ancestry. For instance, many census recipients nominated two European ancestries, tending towards an overcount. Conversely, 29.9% of census recipients nominated "Australian" ancestry, tending towards an undercount.
